Hazard perception · Northern Ireland

A hazard starts scoring when it begins to change what you need to do.

Hazard perception is not about clicking every object that could possibly become dangerous. The important moment is when something develops in a way that may make you change speed, direction or position.

Potential versus developing

A parked car is a potential hazard. If its indicator comes on, the wheels turn and it begins moving away from the kerb, it has become a developing hazard because you may now need to slow or change position.

Look for change

Useful clues include movement, brake lights, indicators, a pedestrian changing direction, a cyclist looking over a shoulder, a vehicle creeping at a junction, narrowing space or worsening visibility.

Plan before the emergency

The strongest hazard-perception response normally comes before the situation becomes an emergency. Scan well ahead and ask what could force you to alter your current driving plan.
