Abstract

Background

The Hispanic population is one group that is involved in a disproportionately high percentage of fatal motor vehicle collisions in the United States.

Study objectives

This study investigated demographic factors contributing to a lack of knowledge and awareness of traffic laws among Hispanic drivers involved in motor vehicle collisions (MVCs) in southern California.

Methods

The cross-sectional study enrolled adults (n = 190) involved in MVCs presenting to a Level I trauma center in southern California over a 7-month period. Subjects completed a survey about California traffic law knowledge (TLK) consisting of eight multiple-choice questions. The mean number of questions answered correctly was compared between groups defined by demographic data.

Results

The mean number of TLK questions answered correctly by Hispanic and non-Hispanic white groups were significantly different at 4.13 and 4.62, respectively (p = 0.005; 95% confidence interval -0.83 to -0.15). Scores were significantly lower in subjects who were not fluent in English, had less than a high school education, did not possess a current driver's license, and received their TLK from sources other than a driver's education class or Department of Motor Vehicle materials. Analysis of variance showed that the source of knowledge was the strongest predictor of accurate TLK.

Conclusion

Source of TLK is a major contributing factor to poor TLK in Hispanics. An emphasis on culturally specific traffic law education is needed.
