This study examines Hispanic migrant farm workers' driving behaviors and knowledge of the laws. These laborers worked and drove in California's agricultural region up to 8 months a year. Results are based on 167 face-to-face interviews conducted in Spanish at five labor camps and 126 observations conducted at these same camps in California. Most drivers were male licensed drivers (79%), who learned to drive at ages 8-14 in Mexico (42%). Those licensed in Mexico versus the US received more citations and unlicensed drivers were rated with poor driving skills. Drivers reported 'always' using seat belts (86%), yet admitted not buckling up within the previous 2 months. Observational data showed that only 37% used belts and 55% of drivers riding alone were belted. Reasons for non-use reflected cultural and economic issues and lack of effective media safety campaigns for this group. Most (75%) drivers with children (< 4 years) said they used child safety seats and others with 1+ children (< 4 years) used no safety seats (20%) or only one seat (53%). Observations showed that regardless of the number of riders aged 0-4, the number of car seats never exceeded one. In 66% of the cars where a single child was carried and where two children were carried, no car seats were used. In all of these cases there were other passengers and drivers who were not belted.
