The definition of reaction time, in terms of driving, is how long it takes you to react to an emergency: by hitting the brakes, turning the wheel, etc.
For most people, this time is approximately 1 second, which at a speed of 60 mph is about 90 feet. So if the emergency occurs within that distance, you probably won't have had time to avoid the accident.
Many insurance companies, however, use a much stricter standard of 1.5 seconds (135 feet), this being (on average) the amount of time it takes to recognize an emergency, decide upon an action, and then execute it.
This is one reason why you're supposed to keep a minimum of four car lengths (2 seconds) between you and the car you're following while at freeway speeds.
That could be argued; but reaction time can be adjusted for with driving habits.
Driving reaction time is the time taken for a driver to see something in the road ahead and to react. This is separate to the braking distance.
When driving, reaction time is slower after consuming alcohol, using drugs, or feeling tired. These impairments can delay your ability to respond quickly to unexpected situations on the road, increasing the risk of accidents. It's important to avoid driving under such conditions to ensure your safety and the safety of others on the road.

Reaction time
A longer reaction time and increased control over the vehicle.
the effect of alchol is: it makes you sleepy tiered when you are driving it makes your vision blurry and it and it also slows your reaction time when driving :]!
Reaction time is important because it is being able to respond quickly and appropiately to situations. An example is when you are driving on a dangerous road and someone swerves into your lane then you would be able to swerve away. But if you are intoxicated you don't have good reaction time.
Probably the most annoying thing for me when driving is tailgaters. They have no sense of their own or my reaction time, endangering us both
