Are radar detector users less safe than nonusers?

One hundred and seventy-four drivers who had purchased special insurance coverage during 1988-1989 for in-vehicle equipment that included a radar detector were compared to a similarly sized and sociodemographically stratified driver population random sample. It was found that the radar detector owners had significantly more accident claims and speeding convictions during the period 1986-1989 than those representing the general driver population.
