Braking
Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time.
Average driver reaction time is about three&-fourths of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20m (66 ft), which could be a lot of distance in an emergency.
Helpful braking tips to keep in mind include:
○ Keep enough distance between you and the vehicle in front of you.
○ Avoid needless heavy braking.
○ Keep pace with traffic. If the engine ever stops while the vehicle is being driven,
brake normally but do not pump the brakes. Doing so could make the pedal harder
to push down. If the engine stops, there will be some power brake assist but it
will be used when the brake is applied. Once the power assist is used up, it can
take longer to stop and the brake pedal will be harder to push.
