Record the appropriate code for road surface conditions at the time of the crash.
The roadway surface condition at the time and place of a crash.
It is important to identify and correct high wet-surface crash locations and provide information for setting coefficient of pavement friction standards. This is critical for prevention programs and engineering evaluations.
- If the value of Road Surface is ‘dry,’ Weather Condition cannot be ‘rain’, ‘snow’, ‘sleet’, ‘hail’, or ‘freezing rain’. Note: This may not apply in unusual locations, such as a tunnel.
- If the crash occurred between May and September, the value of Road Surface Condition should not be ‘snow’, ‘ice’, or ‘slush’.
