WSDOT – Collision Data Request

Lee contacted

Dave Dean

WSDOT Eastern Region

Route Development Engineer



Dave Dean obliged by giving us this link to a WSDOT freedom of information collision data requst form. No doubt Ken Helms from ISDOT could do the same for Idaho.

I’m not sure if “collision” is being used generally to include one vehicle run off incidents. If it did, it would be useful in arguing for or against the necessity of rumble strips such as though appearing going north to Colton.

Thanks, Lee
