What is reaction time ? On what does the reaction time depend ?
The driver of the moving vehicle has to apply brakes instantly to avoid accident if any person or another vehicle or any obstacle is there in the path. The time taken to come out of this situation, to think and to implement is called reaction time.
Reaction time depends on the situation and the person.
