Final answer:
It's safest to avoid braking on the shoulder of the road until your speed is below 20-25 mph to prevent loss of vehicle control.
Step-by-step explanation:
When leaving the road on the shoulder, it is safest to avoid braking until the speed is less than 20-25 mph if possible. The reason behind this is that braking at high speeds while on the shoulder can cause loss of vehicle control, especially if the shoulder is made of a material that provides less traction than the road, such as gravel or dirt. It is important to decelerate gradually by lifting your foot off the gas and only apply the brakes gently once the speed is reduced. Braking sharply at high speeds on a road shoulder can lead to skidding or losing control of the vehicle, potentially resulting in an accident.
