Which action conflicts with safe procedures when backing toward a loading dock?
Correct answer: C – Continue backing until the vehicle contacts the dock instead of verifying clearance
Washington safe-backing guidance calls for checking the intended path and clearance before beginning. Back slowly, use both mirrors, and use a helper whenever possible. If clearance becomes uncertain, stop and get out to check the vehicle’s position. Continuing until impact rather than verifying the remaining space is not a safe backing procedure.
