Final answer:
The proper interval for following another vehicle to avoid traffic accidents is a three-second interval, known as the Three-Second Rule. This time should be increased in poor driving conditions, and a longer following distance is necessary at higher speeds to ensure safe stopping and reaction times.
Step-by-step explanation:
To avoid traffic accidents caused by following too closely, the recommended safe interval for following behind another vehicle is typically the Three-Second Rule. This means that when the rear end of the vehicle ahead of you passes a fixed point, such as a sign or pole, it should take at least three seconds before the front of your vehicle reaches the same point. This interval allows for proper reaction time and stopping distance in case the vehicle in front stops suddenly. In conditions where visibility or traction is compromised, such as in rain, fog, or snowy conditions, this interval should be increased to ensure safety.
It's important to adapt the following distance based on speed as well. For example, at higher speeds, a longer following distance is required because your vehicle will travel further during the time it takes for you to react. Bridget's classroom observation of the time it takes for cars to travel between two poles can be related to this principle. Given that the speed limit in towns and cities is often around 60 km/hr, maintaining adequate space between vehicles is crucial to crossing roads safely and to accommodate necessary stopping distances.
