What is the most accurate method to determine proper following distance?

The most reliable method drivers use to gauge this distance is by counting seconds. To do this, pick a stationary object on the side of the road, like a road sign or overpass, and, as soon as the vehicle in front passes your chosen object, begin counting: “one-one-thousand, two-one-thousand…”.

How many car lengths is 2 seconds?

The two-second rule is useful as it works at most speeds. It is equivalent to one vehicle- length for every 5 mph of the current speed, but drivers can find it difficult to estimate the correct distance from the car in front, let alone to remember the stopping distances that are required for a given speed.

What is 1 second for every 10 feet of vehicle length?

One good rule for how much space you should keep in front of you is at least 1 second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and the vehicle ahead.

What is safe following distance when driving?

What’s good about the “3 second rule” is that it helps you keep a safe following-distance at any speed. Using the “3 second rule” gives you a bigger following-distance the faster you drive. Generally speaking, you should allow more than a 3 second following-distance in rain, fog and on icy roads.

What is the minimum number of seconds needed for following distance?

Many drivers follow the “three-second rule.” In other words, you should keep three seconds worth of space between your car and the car in front of you in order to maintain a safe following distance.

What is the number 1 unsafe driving behavior?
