Question

Difficulty: EasySpace Overhead

If you are uncertain whether your commercial vehicle has sufficient overhead clearance to safely pass under a bridge or low-hanging structure, you should slowly drive forward and stop only if you hear or feel contact.

Answer: Answer

Answer

False
The statement is false because professional driving standards explicitly state that if there is any doubt about overhead clearance, you must not attempt to drive under the structure. You should stop safely and take another route or confirm the height before proceeding.

Step-by-Step Solution

1
Identify the safety hazard associated with uncertain overhead clearance.
Attempting to pass under an unknown or low clearance can lead to severe structural collisions, trailer roof collapse, or getting wedged.
Commercial motor vehicles have rigid height profiles and significant kinetic energy even at slow speeds.
2
Evaluate the correct CDL safe operating procedure when overhead clearance is questionable.
Drivers must never attempt to squeeze through or use vehicle contact as a test of clearance.
Safe space management rules require stopping safely, verifying clearance, or redirecting to an alternate designated truck route.

Key Concept

Commercial drivers must never attempt to squeeze through or guess clearance when approaching a questionable overhead obstacle; they must stop safely and verify clearance or take an alternate route.
