A vehicle with brakes and tires in good working condition traveling at 90 kmh [60 mph] covers 27 metres [88 feet] per second. Stopping a vehicle traveling at this speed involves recognizing the need to stop, initiating braking and then braking to a stop At 90 kmh, once braking starts, it takes 42 metres to come to a complete stop. This encompasses approximately 3.1 seconds. So from perceiving a braking situation to stopping, takes 4.6 seconds during which time the car travels over 82 metres, which is almost the length of a football field. These computations are based on dry pavement, using an average braking rate of .870 g A vehicle with brakes and tires in good working condition traveling at 90 kmh [60 mph] covers 27 metres [88 feet] per second.
