This report provides procedures for administering and scoring the Automobile Driver On-Road Performance Test (ADOPT). The ADOPT checks 21 separate driving performances. Performances are checked at pre-determined locations along a 10-minute route and are scored against specified criteria. The highly objective scoring system produces correlations across examiners in excess of .8 and correlations across routes in excess of .7. The ADOPT is primarily a measure of skill. While many of the performances checked do not require skill to perform (e.g., signaling, mirror checks), a high level of skill is required to perform them and maintain control of the vehicle at the same time. The ADOPT as a whole correlates approximately .5 with a measure of the vehicle handling skills.
