What should you do if you cannot determine overhead clearance?

• A. Find another route
• B. Proceed slowly and hope to clear
• C. Ignore and continue if space seems enough
• D. Turn back immediately

Answer: (A)

If you can’t determine overhead clearance, you should choose a route with assured height and detour around the potential obstruction. This is about not risking a collision with a low bridge, arch, overhead sign, or other structure when the vehicle’s exact height isn’t known. You can’t rely on guesswork or perspective to gauge clearance accurately, and misjudging can lead to expensive damage, traffic hazards, and injuries. That’s why finding another route is the safest option. Proceeding slowly and hoping to clear, ignoring the space, or turning back only in a limited way doesn’t reduce the risk enough and can still put you or others in danger.
