## How many feet should you stay behind a car while driving?

The rule of seconds advises that if you're driving below 40 mph, you should maintain at least one second of distance for each 10 feet of vehicle length. Over 40 mph, add an extra second. For a truck driver cruising in a longer, heavier vehicle, more space and time is needed. via

## How many car lengths back should you be for each 10 mph of speed?

## Is it 2 or 3 second rule?

## What is the rule of thumb method of determining a safe following distance?

The rule of thumb is to maintain at least a three-second following distance, giving you time to react and avoid potentially dangerous situations. You can calculate this by using a fixed object, such as a pole or an overpass to determine how far in front of you the car is. via

## What is tailgating a car?

Following too closely behind another motorist, or tailgating, is an aggressive driving behavior. via

People used to determine proper following distance using the number of car lengths between them as a reference. Now, the best way to make sure you're not following others too closely is to use the second rule. via

## What is the 4 second rule?

A 4-second following distance, as shown above in Area 1 of the space-management diagram, will allow you to steer or brake to avoid a hazard safely on the highway, if the pavement is dry. If you are following too closely and the vehicle ahead of you stops or slows suddenly, you will not be able to avoid a crash. via

## How do you measure 100 feet while driving?

To roughly estimate how far 100 feet is when driving, consider that you can travel about 100 feet in one second if traveling 60 mph or in two seconds if traveling 30 mph. However, a better way to familiarize yourself with 100 feet would be to measure and mark the distance. via

## How can you count following distance?

Calculating this rule is fairly simple. Basically, you should always allow three full seconds between yourself and the vehicle in front of you. You can do this by using a specific point ahead such as a sign that you see on the side of the road, and then count “one-thousand-one, one-thousand- two, one-thousand-three.” via

• Interdependence.
• Magnitude Dependent.
• Value-Based.
