 Introduction: 
                                        Car accidents in developing countries 
                                        are one of the major causes of mortality 
                                        and injuries. Human errors are the most 
                                        important causes of traffic accidents. 
                                        The skill of safe driving a taxi was an 
                                        important part of job behaviors for drivers 
                                        of public transport.The aim of this study 
                                        was to determine the factors affecting 
                                        driving errors in Taxi Driversdriving 
                                        Behaviors across Kermanshah 2015.
 Methods: 
                                        The descriptive cross-sectional study 
                                        was performed in 2015. Data were collected 
                                        from the cluster random sampling that 
                                        was employed, and in the final volume 
                                        of sample population 226 subjects were 
                                        selected.The samples consisted of all 
                                        interurban taxi drivers with a driving 
                                        license and at least one year of driving 
                                        experience. Data were collected using 
                                        two questionnaires, a researcher-made 
                                        questionnaire and the Manchester Driving 
                                        Behavior Questionnaire. The validity of 
                                        the first questionnaire was confirmed 
                                        by the experts opinions while the 
                                        second questionnaire was validated in 
                                        previous studies. The qualitative and 
                                        quantitative analysis of data was conducted 
                                        using the SPSS Statistics Software Version 
                                        20.0. Findings: The 
                                        reliability of the Manchester driving 
                                        behavior questionnaire measured 0.92. 
                                        Exploratory Factor Analysis showed differences 
                                        between slips, lapses, deliberate violation 
                                        and unintentional violation clearly. Internal 
                                        consistency were unintentional violation 
                                        0.42, deliberate violation 0.85, lapses 
                                        0.77 and slips 0.88. The most dangerous 
                                        driving behavior related to slips and 
                                        deliberate violation. Conclusion: 
                                        The findings of this study show psychometric 
                                        properties of dangerous driving behavior 
                                        in deliberate violation and slips in Kermanshah 
                                        taxi drivers. it is suggested that driving 
                                        teaching workshops and safety driving 
                                        education are initiated for Kermanshahs 
                                        taxi drivers.
 Key words: Manchester Questionnaire, 
                                        Driving behavior, taxi driver.

 Car accidents and their consequences, especially 
                                in developing countries, are seen as one of the 
                                major causes of mortality and injuries. In addition 
                                to economic losses, car accidents pose serious 
                                loss of life in Iran (1). It is estimated that 
                                roughly two million people lose their lives as 
                                a result of car accidents in the world annually 
                                (2). The estimated number of driving casualties 
                                is over 15 million people per year (3), and Iran 
                                is no exception, but what distinguishes Iran from 
                                other countries is the growing trend of car accidents 
                                compared to other countries. In most countries, 
                                the growth trends of the accident index have been 
                                either negative or sluggish from 1990 to 1993. 
                                For instance, this trend has measured 18% in France, 
                                16% in England, 7% in Denmark, 2% in Pakistan, 
                                and 1.2% in India, while the very same index measured 
                                55% in Iran between 1994 and 1996 (4). In other 
                                words, the mortality rate resulting from car accidents 
                                was 29 deaths per 10,000, while the very same 
                                index indicated 1-2.5 people for developed countries 
                                and 3-15 persons for developing ones (4).
 In Iran, 64 people are killed in car accidents 
                                  every day, and 1967 injured people are hospitalized, 
                                  of which 640 people are disabled in car accidents. 
                                  Every day, the incomes of 450 families are severely 
                                  decreased, and with the assumption of the existence 
                                  of four people in each family, about 1,300 people 
                                  are severely affected by the financial pressures 
                                  of death or disability in the family. Every 
                                  year, 23,300 are killed and 718,000 are injured 
                                  in car accidents, of which 200,000 victims are 
                                  disabled. In other words, a total of 753,000 
                                  Iranians (equivalent to one percent of the whole 
                                  population of Iran) are killed or injured. The 
                                  estimated costs of accidents outside cities 
                                  alone have been 10 times higher than the budget 
                                  allocated to the construction and maintenance 
                                  of roads. If the effects of human factors are 
                                  controlled, accidents and driving violations 
                                  will probably be reduced (5).  Driving violations have always been one of 
                                  the leading causes of traffic problems and accidents 
                                  in all societies, and their rates and types 
                                  are different depending on the cultural, socioeconomic 
                                  and geographical contexts of societies. Notwithstanding 
                                  the environmental, controlling and executive 
                                  factors as well as the disproportion of road 
                                  structures to the number of vehicles and traffic 
                                  units and other factors contributing to driving 
                                  violations, the human factors, as the leading 
                                  cause, constitute the highest percentage of 
                                  violations. One of the major duties of health 
                                  researchers is to conduct research into the 
                                  related issues with the aim of having a more 
                                  accurate classification and understanding of 
                                  human factors that play prominent roles in road 
                                  accidents. It is noteworthy that all human factors 
                                  involved in driving accidents are not covered 
                                  by rectifying human errors by any means. In 
                                  fact, its important to distinguish between 
                                  errors and violations (6).  Errors are interpreted as ones inability 
                                  or failure to make sound judgments or to perform 
                                  a series of designed actions to achieve the 
                                  intended results (7). Violations are those behaviors 
                                  that endanger the driving safety, for example, 
                                  excessive speed or driving without observing 
                                  the safe following distance from other vehicles 
                                  ahead (8). According to consensus, errors are 
                                  categorized into two distinct types. The first 
                                  type is about errors that are caused by problems 
                                  in attention, memory and information processing, 
                                  which include two major categories: lapse and 
                                  slip. The first type refers to errors that are 
                                  caused by the wrongly adopted approaches to 
                                  achieve a goal without awareness of ones 
                                  wrong choice. Violations fall into two major 
                                  categories: unintentional violations (e.g., 
                                  driving too slowly on narrow two-lane highways) 
                                  and deliberate violations (e.g., overtaking 
                                  other cars on solid white lines in crowded two-way 
                                  roads) (9). Various studies have referred to the role of 
                                  human factors as the main cause of traffic irregularities, 
                                  particularly in driving offenses and accidents. 
                                  Disregard for traffic regulations and evasion 
                                  of law as the causes of problems, dilemmas and 
                                  traffic accidents in many societies depend on 
                                  the cultural, social, economic and geographical 
                                  conditions of societies. The statistics in Iran 
                                  are indicative of the high and unusual rates 
                                  of driving violations which cause irreparable 
                                  economic losses and social damage, not to mention, 
                                  human factors have been reported as the main 
                                  cause of driving violations (10). All interurban 
                                  taxi drivers are to have the required knowledge 
                                  and various skills to provide safe travel service 
                                  in the urban transport fleet. Further, they 
                                  must all have a driving licence class B2 and 
                                  adopt the correct driving behaviors while moving 
                                  along the traffic and avoid accidents using 
                                  their driving skills. In a study conducted on 293 drivers with driving 
                                  licence class B2 in Isfahan, Iran, Oreyzi and 
                                  Haghayegh (2009) assessed the reliability and 
                                  validity of Manchester driving behavior questionnaire 
                                  and determined the types of traffic anomalies. 
                                  First of all, lapses, slips, unintentional violations 
                                  and deliberate violations were differentiated 
                                  from each other to examine the validity of the 
                                  instrument through the exploratory factor analysis. 
                                  The results of the final analysis showed that 
                                  all four factors had high internal consistency: 
                                  unintentional violations (0.65), deliberate 
                                  violations (0.86), lapses (0.81), and slips 
                                  (0.77). The results of this study demonstrated 
                                  that the Manchester driving behavior questionnaire 
                                  could be used as a valid and reliable instrument 
                                  for assessing the driving behaviors (11).  In a descriptive and analytical study conducted 
                                  on 1,286 interurban drivers in the United Arabic 
                                  Emirates by Beneret al. (2011), the driving 
                                  behaviors were investigated in terms of unintentional 
                                  violations, deliberate violations, lapses, and 
                                  slips. The results indicated that the unintentional 
                                  violations, lapses, deliberate violations and 
                                  slips accounted for 48%, 10.6%, 7.2% and 6.3% 
                                  of injuries caused by accidents, respectively 
                                  (12). The results showed that there was a difference 
                                  between the errors and violations performed 
                                  by the subjects under study. Furthermore, the 
                                  rates of slips, violations and lapses were higher 
                                  compared to those in Australia and European 
                                  countries (13). In a study performed on driving examinees in 
                                  Shiraz, Iran, 537 subjects were selected using 
                                  convenience sampling through visiting places 
                                  such as the center for replacement and issuance 
                                  of license plates and a central specialized 
                                  clinic based in Shiraz. For data collection, 
                                  a demographic questionnaire, the Manchester 
                                  driving behavior questionnaire, and NEO Personality 
                                  Inventory were utilized. In addition, correlation 
                                  and variance analysis were usedfor data analysis. 
                                  The results of this study demonstrated that 
                                  there was a significant positive relationship 
                                  between the scores of neuroticism and the levels 
                                  of error types and unlawful actions (p<0.05). 
                                  Additionally, it was shown that the scores of 
                                  agreeableness and extraversion significantly 
                                  and inversely correlated with the levels of 
                                  error types and unlawful actions (p<0.05). 
                                  It was demonstrated that only the factors of 
                                  age and years of driving experience significantly 
                                  and negatively correlated with dangerous violations 
                                  (p<0.05). Interestingly, there was a significant 
                                  positive relationship between the years of formal 
                                  education and each of the rates of error types 
                                  and dangerous violations (p<0.05). Also, 
                                  the results indicated that there was a significant 
                                  relationship between the personality traits 
                                  and driving behaviors (14). The results of Ozkan 
                                  et al. study (2006) on 242 drivers selected 
                                  from Finland, England, Greece, Iran, Norway 
                                  and Turkey showed that lapses were the most 
                                  common factor in connection with driving accidents, 
                                  and a relationship was found between the patterns 
                                  of driving behaviors and accidents. So, it was 
                                  concluded that driving accidents could be estimated 
                                  based on the patterns of driving behaviors (15). Given the significance of this skill, the necessity 
                                  of correct driving behaviors to minimize loss 
                                  of life and property caused by accidents, lack 
                                  of previous research in this respect across 
                                  Kermanshah, and the fact that a major portion 
                                  of urban transport is performed by interurban 
                                  taxi drivers, the present study aimed to investigate 
                                  the interurban taxi driversdriving behaviors 
                                  across Kermanshah, Iran, in 2015.
 The descriptive cross-sectional study was performed 
                                  in 2015. The statistical population consisted 
                                  of all interurban taxi drivers with a driving 
                                  license and at least one year of driving experience. 
                                  As for sampling, the cluster random sampling 
                                  was employed, and the final volume of sample 
                                  population was estimated to be 200 taxi drivers 
                                  based on the fact that there were 260 interurban 
                                  travel agencies across Kermanshah which fell 
                                  into 20 clusters, and 10 people were selected 
                                  from each cluster. The final volume of the sample 
                                  population was estimated to be 184 taxi drivers 
                                  using the study performed by Oreizy and Haghayegh 
                                  (2009), but 220 subjects were selected due to 
                                  the possibility of sample attrition. After the 
                                  distribution and collection of questionnaires, 
                                  the final volume of the sample population reached 
                                  226 subjects. To encourage the taxi drivers 
                                  to complete the questionnaires, one car air 
                                  freshener was given to each of the participants(11). For data collection, a researcher-made demographic 
                                  questionnaire and the Manchester driving behavior 
                                  questionnaire, were utilized. In addition, the 
                                  face and content validities of the demographic 
                                  questionnaire were approved by a panel of 10 
                                  faculty members at Kermanshah University of 
                                  Medical Sciences. The Manchester driving behavior 
                                  questionnaire was developed by Reason et al. 
                                  (1990) in the Department of Psychology at the 
                                  University of Manchester. Furthermore, the reliability 
                                  and validity of this instrument has been confirmed 
                                  in different countries of the world, including 
                                  Iran (11). This questionnaire was designed based 
                                  on the basic theory that errors and violations 
                                  have different psychological causes and correction 
                                  procedures, and they should be differentiated. 
                                  Moreover, given the prohibition of alcoholic 
                                  beverages in most countries the questions relating 
                                  to the permitted consumption of alcoholic drinks 
                                  were modified.. Also, this questionnaire consisted 
                                  of 50 items with five-point Likert scale (0=never, 
                                  1=rarely, 2=sometimes, 3=often, 4=usually, 5=Always). 
                                  The questions were different in two aspects: 
                                  the kind of behaviors and the extent of danger 
                                  that the behavior causes for other drivers. 
                                  The abnormal behaviors fall into four categories: 
                                  lapses, slips, unintentional violations, and 
                                  deliberate violations. Also, in terms of the 
                                  extent of danger that each of these categories 
                                  cause for drivers, there are three categorizations: 
                                  1) low-risk, 2) average-risk, and 3) high-risk 
                                  (see Table 1). The qualitative and quantitative analysis of 
                                  data were conducted using the SPSS Statistics 
                                  Software Version 20.0.Furthermore, the statistical 
                                  tests of mean and variance were employed for 
                                  the descriptive analysis of the demographic 
                                  characteristics and driving cultures of the 
                                  samples under study. To investigate the factor 
                                  structure of the Manchester driving behavior 
                                  questionnaire, the principal components analysis, 
                                  one of the procedures of exploratory factor 
                                  analysis, with varimax rotation method were 
                                  utilized and items were operating under factor 
                                  loading to separate from each other factor and 
                                  will be calculated error. After performing the 
                                  factor analysis; the internal consistency was 
                                  analyzed based on the extracted factors. To 
                                  commence the study, the required permits were 
                                  obtained from the Vice Chancellery for the Department 
                                  of Research and Technology at Kermanshah University
