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-quarters 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:
If the engine ever stops or a brake fault occurs, the brakes may lose power assist. More effort will be required to stop the vehicle. It may take longer to stop.
If equipped, there is a small convex mirror built into the upper and outer corner of the driver outside mirror. It can show objects that may be in the vehicle's blind zone.
Driving with the Blind Spot Mirror
Actual Mirror View
When the approaching vehicle is a long distance away, the image in the main mirror is small and near the inboard edge of the mirror. As the vehicle gets closer, the image in the main mirror gets larger and moves outboard. As the vehicle enters the blind zone, the image transitions from the main mirror to the blind spot mirror. When the vehicle is in the blind zone, the image only appears in the blind spot mirror.
