In Washington, RCW 46.61.680 makes it illegal to operate a passenger vehicle that has been modified to lower its clearance below legal limits. This law ensures that vehicle modifications adhere to safety standards. If the vehicle’s clearance is too low—where any part of the vehicle, aside from the wheels, sits lower than the bottom rim of the wheels—the vehicle violates RCW 46.61.680.
Key Aspects of RCW 46.61.680
