The findings of the research indicate that the specification values for perception-reaction time are too low for the stopping-sight-distance design standards and the vehicle-clear ance-interval standard. WebbWhile a racing driver who is expecting to have to brake might react in half a second or less, drivers in real life are relatively complacent and reaction times of 1.5-2 seconds are the norm. In older drivers this can be as high as 2.5 seconds. Factors that affect braking distance Brakes Brakes slow a car down using friction.
