Abstract
Most of the evidence on t e relationship between medication & safe driving depends on laboratory psychological tests or gymkhana like road trials. These methods only test part of the whole skill of driving in traffic. Epidemiological evidence will be needed to back up the results from the laboratory approach. It will be very difficult and expensive though essential to obtain. Drug estimations in road accident fatalities may reveal whether the ranking order of classes drugs found in them differs from the known order of classes of drugs prescribed.
