Answer:
Reaction distance
Step-by-step explanation:
Reaction distance can simply be defined as the distance covered from the moment a hazard is detected to when the driver begins braking or swerving.
In a nutshell, it measures how quick a driver can react to hazards encountered while plying the road.
The reaction distance can be decreased by being aware on the road (increased awareness) and by anticipating hazards. Anticipating hazards makes you relaxed and able to react quickly to sudden hazards.
