In case of a truck fire, after signaling to move to the shoulder, what should a driver do next?

Answer: A — Exit the vehicle immediately

In the event of a truck fire, the safest course of action after signaling to move to the shoulder is to exit the vehicle immediately. This is crucial because the risk of injury or fatality increases significantly when remaining inside or attempting to manage the situation from within the cab. Fires in vehicles can escalate rapidly, and the fumes or smoke can be hazardous. Leaving the vehicle allows the driver to put distance between themselves and the fire, thereby reducing the potential for burns or inhalation of toxic smoke. It is also important to move to a safe location away from the vehicle, as tires can explode or other dangerous reactions can occur as the fire progresses. Remaining in the vehicle, attempting to extinguish the flames, or inspecting the cargo can pose serious risks and may impede the driver from escaping effectively. Prioritizing personal safety by exiting the vehicle promptly is the key factor that ensures a better outcome in such emergencies.
