Road Safety and Accident Prevention: Anticipating and Reducing Risk
Safety as anticipation
Most collisions are avoidable. Safe drivers scan far ahead, keep space, manage speed and expect errors from others. Learn the causes of collisions (excess speed, distraction, following too closely, alcohol, fatigue, poor observation) and the defensive techniques that counter them.
Space and time
Maintain a safe following distance - commonly expressed as the two-second rule in good conditions, increased in rain, at night or behind large vehicles. Stopping distance equals thinking distance plus braking distance; both grow with speed, and braking distance grows much faster than thinking distance. Wet roads can roughly double braking distance; ice can multiply it several times.
Vulnerable road users
Pedestrians, cyclists, motorcyclists and children are hardest to see and most easily hurt. Give them extra room, expect sudden movements near schools, parked cars and bus stops, and check blind spots before turning. When passing a cyclist, leave generous lateral clearance.
Hazard perception
Look for clues: brake lights ahead, a ball rolling into the road, a parked car with an occupied driver's seat, or a pedestrian hesitating at a kerb. Treat these as warnings, not coincidences.
Traps
Questions often contrast reaction with prevention. Choosing “brake hard” when “slow early and increase space” is available is usually the weaker answer. Another trap is asking what to do when dazzled or tired: the safe answer is to slow, stop somewhere safe and rest, not to push on.
Rule of thumb: If you can see a hazard developing but have not yet planned a response, you are already late. Scan 12–15 seconds ahead in town and further on open roads.
Worked example: Rain begins and visibility drops. The best response is to reduce speed, increase following distance beyond two seconds, and switch on appropriate lights - not merely to keep the same speed with wipers on.
