When driving, you should always measure your following distance in seconds. A general rule of thumb is to maintain a following distance of at least 3-4 seconds between your vehicle and the one in front of you. This distance allows you enough time to react and brake safely in case of an emergency.
You should always measure your following distance by car length. This will give yourself time to break when necessary without being close to the driver ahead of you.
car lengths
It depends on how long a distance you want to measure!
Following distance is typically measured in seconds. A common rule of thumb is the "3-second rule" where you should leave at least 3 seconds of following distance between your vehicle and the vehicle in front of you. To measure this, pick a stationary object on the side of the road, wait for the vehicle ahead of you to pass it, and then count how many seconds it takes for you to pass the same object.
It is best to measure it in the most easiest measurement, e.g. kilometres for journeys but millimetres or centimetres for construction. It is also easiest to measure using the metric system because they can easily be converted. But, in some cases, it is important to either measure or record the measurement as metres because it is the international SI units e.g. international projects such as probe design.
The rule of thumb is one car length for every 10 miles per an hour that the car you are driving is traveling. For example: You are traveling 70 miles an hour on the interstate, the car you are following should be seven car lengths ahead of you.
Yes, absolutely, always give the vehicle ahead of you room to maneuver especially a motorcycle. Your car or truck has no problem running over a motorcycle and its riders.
You should probably not be following one in the first place.
Under normal conditions a safe following distance between your car and a motorcycle should be?
If you look at the bottom of the map, there should be a scale. Take a ruler, measure the distance for each measurement, and convert to what you need
It is your following distance. You should be able to stop within the distance of you and the car in front of you. However if you should have a vehicle that is following you real close, you should give yourself a larger area of cushion.
