Highway safety program standard 5, driver licensing, issued by the us department of transportation requires, in part, that the states test applicants for a renewal of their operator's license on rules of the road at least once every 4 years. The state of virginia requested a waiver of the knowledge testing portion of the standard until evidence could be presented to show that it had the desired safety benefit. The virginia highway and transportation research council and the virginia division of motor vehicles conducted an experimental evaluation of several alternative approaches to implementation of the standard. This evaluation randomly assigned members of the renewal population of drivers to four study groups: (1) a control group receiving no treatment; (2) a group that received only a driver's manual; (3) a group that received a manual and a test to be taken at home; and (4) a group that received a manual and were requested to take a test in the DMV examining station at the time of application for license renewal. The subsequent driving performance of members of the four groups was monitored and data for accidents, major convictions, minor convictions, accidents with associated convictions, and administrative actions taken under provisions of the driver improvement program were tabulated at 6-, 12-, 18-, and 24-month intervals. For the two groups administered a knowledge test, comparisons were made of the performance of those who had passed, failed, or refused to take the test. The results obtained supplied no substantial evidence for requiring the re-examination of the general renewal population.
