Reaction time is how many seconds it takes the drivers vehicle to pass a target after the vehicle in front has passed it__
Answer:
4 seconds
Explanation:
Legally, cars should be at least 4 seconds apart, so when the car in front of you passes a object and you count how many seconds it takes you. 4 seconds is a good distance, over 4 is still safe, but under 4 is too close to the car ahead of you.
