When should you start braking when exiting the interstate?

The correct approach is to begin braking on the exit ramp. As you exit the interstate, it is crucial to transition smoothly from high-speed driving on the interstate to a slower speed on the exit ramp. Doing this ensures not only your safety but also the safety of other motorists who may be traveling at different speeds.

When you start to brake on the exit ramp, you allow yourself ample time to reduce your speed to align with the posted speed limits and conditions. This practice aids in maintaining control of your vehicle and enhances reaction time for any surprises that might arise, such as changes in road conditions, pedestrians, or other vehicles.

Braking just before the exit or at the beginning of the exit lane might not give you enough distance to safely reduce your speed, which could lead to sudden stops or loss of control. Braking after passing the yellow posted ramp speed sign is also not advisable, as it is essential to start adjusting your speed before reaching the sign to allow for a more controlled descent to the appropriate speed limit. Hence, focusing on braking on the exit ramp itself is the best method to achieve a safe transition.
