The evaluation is a two-part assessment. The initial pre-driving evaluation is an office-based neuropsychological assessment designed to assess thinking skills necessary to being able to safely operate a motor vehicle. This evaluation is composed of a reliable and valid computer based test which assesses processing speed, divided attention, and focused attention. Additional paper and pencil or question and answer type tests are administered that assess attention/concentration, processing speed, spatial abilities, visual search and scanning, directional sense, problem solving, and learning and memory. This part of the assessment takes approximately 3 hours.
The second phase of the assessment is the behind the wheel evaluation. This part of the assessment is conducted by a Certified Driver Rehabilitation Specialist (CDRS). A permit or valid driver's license is required for this phase of the assessment. The specialist meets the client at his/her home so that the evaluation is conducted in a familiar environment. The client must use the specialist's car for liability and safety reasons, as the car is equipped with a brake on the passenger's side to help prevent an accident if necessary. The client is given time to become familiar with the vehicle. Depending on the client's location the assessment will take place on residential, suburban, and/or city streets and will include highway/expressway driving if appropriate. Speed control, brake reaction time, ability to maintain lane position, judgment and decision making in traffic situations, appropriate use of mirrors, making turns, knowledge of right of way, parking manuevers, multi-tasking, and the ability to plan and follow a route are assessed. The behind the wheel evaluation typically lasts one hour.
