Final answer:
When vehicle's wheel runs off the pavement, the driver should gently steer back onto the pavement and may need to gently brake, following the principles of physics and understanding of friction.
Step-by-step explanation:
If the front right wheel of a vehicle runs off the pavement, it is true that a driver should ease off the accelerator and gently steer back onto the pavement. Applying the brakes gently may also be appropriate depending on the traffic and road conditions, but abrupt or harsh maneuvers might lead to loss of vehicle control or cause an accident. In this situation, the driver's actions are guided by the principles of physics, specifically Newton's laws of motion, and the understanding of friction between the tires and the road.
