A few studies have tried to estimate the association between the presence of antilock brakes in a vehicle and either the risk of a crash or risk of injury in a crash. To date, there is little evidence that antilock brakes are effective. The investigators are conducting a case-control study to estimate the association between the presence of an antilock brake system in a passenger vehicle and the risk of a traffic crash injury. Data from a large insurance carrier will be used for the study. The analysis will adjust for potential confounding factors related to the car and the driver-owner. The final risk ratio estimates will be useful in understanding how antilock brakes may contribute to a reduction in traffic crash injuries.
