Is It Impossible To Figure Out A Safe Following Distance At Any Given Time On The Highway?

How do you calculate safe following distance?

The easiest and quickest way to calculate a safe following distance (the safe amount of distance between you and the car ahead of you) is to use the two-second rule.

Basically, the two-second rule states that you should stay a full two seconds behind the car in front of you, whatever speed you are traveling at..

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.

How many car lengths should you be behind?

Figure one car length for every ten miles an hour,” Barndt said. “So if you’re doing 55 miles an hour you should have six car lengths between you so that if something happens to the car in front of you, you have time to stop or react.” The number two item Barndt says drivers are all guilty of is being distracted.

What is the appropriate following distance for most vehicles?

The two-second rule is a rule of thumb by which a driver may maintain a safe trailing distance at any speed. The rule is that a driver should ideally stay at least two seconds behind any vehicle that is directly in front of his or her vehicle.

When would you need to increase your following distance?

The three-second rule is recommended for passenger vehicles during ideal road and weather conditions. Slow down and increase your following distance even more during adverse weather conditions or when visibility is reduced. Also increase your following distance if you are driving a larger vehicle or towing a trailer.

If you are driving below 40 mph, you should leave at least one second for every 10 feet of vehicle length. For a typical tractor-trailer, this results in 4 seconds between you and the leading vehicle. For speeds over 40 mph, you should leave one additional second.

What is the 3 to 6 second rule?

The 3-second rule only applies to good, daylight driving conditions. If you are driving in heavy traffic, driving at night or in weather conditions that are not ideal, such as rain or fog, consider doubling the 3-second rule to six seconds as a safety precaution.

350 feetThe owners manual for your car will tell you that your stopping distance at these speeds is well over that short piece of highway. The Pennsylvania Drivers’ Manual on page 28 explicitly recommends using the “Four-Second Rule;” At 60 mph, this will have you following at a very safe distance of 350 feet.

How does the 4 second rule determine the proper following distance?

Some Extra Tips: If it takes less than 4 seconds, you’re following to close and have to increase your distance. If it takes 4 or more seconds to pass the checkpoint, you have a safe following distance. Start counting seconds (one-one thousand, two-one thousand, etc.) as it passes the checkpoint.

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.
