3 seconds
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.

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.
Following distance is the space between your vehicle and the vehicle in front of you while driving. Maintaining a safe following distance allows you more time to react to sudden stops or changes in traffic situations, helping to prevent rear-end collisions. The general rule is to keep at least a 3-second distance in good weather conditions, and more in adverse conditions.

You should allow at least 4 seconds of following distance when driving a 30-foot vehicle at 55 mph. This provides enough time to react to any sudden changes in traffic ahead and helps prevent rear-end collisions.
