A commercial driver is reversing a combination vehicle into a congested, poorly lit industrial yard. A designated spotter is assisting, and both have pre-agreed on hand signals. During the maneuver, the spotter gives a continuous 'keep backing' hand signal, but then steps behind a stacked pallet and completely out of the driver's mirror view. Simultaneously, the spotter transmits a clear message over the two-way radio stating, 'I had to move out of the way, but your path is completely clear, keep coming back slowly.' According to CDL safety protocols, what is the driver's required immediate action?
- Stop the vehicle immediately, secure it, and do not resume the backing maneuver until direct visual contact with the spotter is re-established.Cevap
- BStop the vehicle, perform a Get Out And Look (GOAL) inspection to verify the path, and then finish the maneuver using only the mirrors and radio guidance.
- CContinue the backing maneuver at a heavily reduced speed while strictly following the spotter's verbal radio instructions to avoid traffic delays.
- DShift into neutral, sound the city horn twice to signal the loss of visual contact, and slowly creep backward until the spotter reappears in the mirror.
Cevap
The driver must stop the vehicle immediately and wait until direct visual contact with the spotter is fully re-established before moving.
According to commercial driving safety standards, if a driver loses sight of their spotter at any point during a backing maneuver, the only acceptable action is to stop the vehicle immediately. Two-way radios or other forms of audio communication do not override this rule, as visual confirmation ensures the spotter is in a safe location and is actually observing the path.
