    Perception Distance – The distance a vehicle travels while a driver is identifying, predicting and deciding to slow down for a hazard. Reaction Time – The time it takes for a driver to execute a decision once a danger is recognized. via

    How many car lengths is a safe distance?

    The two-second rule is equivalent to one vehicle length for every 5 MPH of the current speed. It's preferable to use seconds to gauge safe distances instead of feet or car lengths because vehicle sizes (and people's depth perception) vary widely. via

    The 2-second rule

    The phrase takes about 2 seconds to say, so if you pass the same fixed point before you've finished saying it, you're too close and should leave more room. In wet conditions, this gap should be at least doubled. In icy conditions, it needs to be increased even further. via

    How many feet should you be behind a car at a stop light?

    Even then, the reaction time of an average person can make the time and distance required to stop even longer. Humans need time to react to what they see, and experts estimate that one foot should be added to every unit of speed for actual stopping time. via

    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

    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

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

    Which method should you use to determine a good following distance?

    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
