Your total stopping distance includes both reaction time and braking distance. Reaction time is the period between recognising a hazard and applying the brakes. During this time, your vehicle continues travelling at its current speed. At 60 km/h, a typical reaction time of 1 to 1.5 seconds means you travel approximately 17 to 25 metres before even touching the brake pedal. Only after this does braking distance begin. This is why following distance and speed management are critical for safety. Factors affecting reaction time include fatigue, distraction, age, experience and impairment. Avoid distractions, stay alert and maintain safe following distances to compensate for inevitable human reaction delays.
