Final answer:
To ensure safety, a driver should slow down when approaching a bump in the road to avoid losing control of the vehicle and to prevent an uncomfortable jolt.
Step-by-step explanation:
When encountering a bump in the road, it's important to assure safety and vehicle control. The appropriate action is to slow down to avoid losing control of the vehicle, as a sudden jolt can be uncomfortable and potentially dangerous. If the car were to go over the bump at a speed faster than what is safe, it could lead to loss of control or even vehicular damage. Conversely, if the car goes over the bump at a slower speed, it minimizes the impact and helps maintain control.
