Washington Utilities and Transportation Commission
In Washington, the commission does not have jurisdiction to exempt railroad crossings within First Class cities. First Class cities have independent authority to authorize the installation of exempt signs. The UTC only has regulatory authority to exempt crossings on industrial or spur lines.
A railroad grade crossing should generally meet the following criteria to be considered for “Exempt” status:
Number of tracks – Maximum of two tracks.
Train traffic – Train traffic at the grade crossing shall not be greater than an annual average of three trains per day.
Train speed – The maximum allowable train speed at the grade crossing shall not exceed 20 miles per hour.
Crossing angle – The horizontal angle between the tracks and the highway shall not be less than 60 degrees.
Sight distance – There shall be a clear and unobstructed view of the grade crossing from any point on the highway for a distance equal to the minimum stopping sight distance for the posted vehicle speed limit and train speed.
