Ontario G1 Driving Practice Test

What is the minimum following distance you should maintain behind the vehicle in front of you?

1. 1 car length.

2. 2 seconds.

3. 3 seconds.

4. 4 car lengths.

The correct answer is: 2 seconds.

Maintaining a minimum following distance of 2 seconds behind the vehicle in front of you is recommended to ensure adequate space to react to unforeseen circumstances. This time-based measurement accounts for various factors such as your speed, road conditions, and the behavior of the vehicle ahead. When you follow a vehicle, counting two seconds allows you to gauge a safe interval that provides enough reaction time in case the vehicle in front makes a sudden stop or encounter obstacles. This method of measuring distance rather than relying solely on physical length is particularly useful because it adapts to different speeds. For example, at higher speeds, even a small gap in car lengths can close quickly, reducing your stopping distance significantly. By using a time-based measure, drivers can adjust their following distance according to their speed and surrounding conditions. Understanding this concept helps you prioritize safety and enhances your ability to anticipate and respond to road situations proactively.
