Modifies requirements for vehicles operating on a paved public highway with a speed limit of more than thirty-five miles per hour with a load of dirt, sand, rocks, or gravel susceptible to being dropped, spilled, leaked, or otherwise escaping from the vehicle.

Requires a person operating a vehicle, from which any object or objects have fallen or escaped, to: (1) Remove the object or objects from the highway if it is safe to do so; or

(2) Notify law enforcement of the situation and remain at the scene until the object or objects have been removed from the highway; and

(3) Pay any costs incurred to remove the object or objects from the highway.

Requires the Washington state patrol, or local law enforcement when appropriate, to enforce these requirements.
