BACKGROUND: THE AIMS OF THIS STUDY INCLUDED: Determination of the most common driver behavior in drivers and also analyzing the relationship between trait anxiety (TA) with subscale of driving behavior (lapses, errors, ordinary and aggressive violations).
METHODS: This cross-sectional study was conducted on 168 drivers that having crash. The self-reporting of the drivers was determined by using Manchester driving behavior questionnaire (DBQ) and Spielberger State-Trait Anxiety Inventory.
RESULTS: Independent t-test showed that violations factor (ordinary and aggressive) are the most common behavior in drivers, Pearson correlation revealed that TA had a significant direct positive relation with all DBQ subscales especially error and lapses factor (P < 0.01) also Pearson correlation showed that age had a negative significant relation with factors of DBQ.
CONCLUSIONS: It can be concluded from the results (according to the relation between TA with error and lapses factor) that the rate of TA is destructive effective on the memory performance and process in the drivers and cause absent minded and memory imperfect function and process in these people during the driving.
