Final answer:
The Three-Second Rule is a driving guideline suggesting a minimum three-second time gap between your car and the one in front to safely react and stop, thus helping to avoid accidents; therefore, the answer is 1) True.
Step-by-step explanation:
The Three-Second Rule in driving refers to the recommended distance you should keep from the vehicle in front of you to avoid accidents. It is a guideline suggesting that there should be a three-second time gap between your car and the car in front, which allows enough time and distance to react and stop safely if the leading car suddenly brakes.
To calculate this, a driver can wait for the leading car to pass a fixed point on the road and then count the seconds it takes for their own car to reach the same point. If it's less than three seconds, they should increase their distance. Increasing this gap in poor weather conditions or when driving at higher speeds is also advisable. This safety rule contributes to reducing the chance of rear-end collisions, particularly in heavy traffic or on highways.
