What is the average reaction time of a driver forced to stop suddenly?

The average reaction time of a driver forced to stop suddenly is typically around 1.5 to 2.5 seconds. This duration includes the time taken to perceive the need to stop, process the information, and execute the braking action. However, various factors such as driver alertness, age, and distractions can affect this reaction time. Consequently, it's essential for drivers to maintain awareness and anticipate potential hazards to minimize stopping distance.
