Before driving a bus equipped with a seat belt at the driver’s position, what must the driver do?
Correct answer: B – Properly adjust and fasten the seat belt
Federal rules prohibit operating a commercial motor vehicle with an installed driver’s seat belt unless the driver is properly restrained. Delaware law also requires a driver operating on a street or highway to wear a properly adjusted and fastened seat belt. The state CDL manual reinforces this rule by instructing bus drivers to use the belt for safety.
