At what speed does the 3-second rule apply?
The three-second rule is ideal for drivers maintaining speeds up to 30 mph. If traveling faster than that, you may need to extend the duration to maintain a safe driving distance.

The 3-Second Rule In Action in California
It's not a law, but it's a guideline that can help you avoid accidents. The rule basically states that leaving at least 3-seconds between your car and the vehicle in front of you is the safest choice.
When you use the 3-second following distance at 55 mph compared to 30 mph, the distance you travel per second is?
When you are driving at 55mph, you are traveling at approximately 80.67 feet per second. At a speed of 30mph, you travel approximately 44 feet per second. The 3-second rule suggests that one should keep a distance that is equivalent to the distance traveled within 3 seconds from the vehicle in front.
How do you calculate the 3-second rule?
you start counting seconds, 'one-thousand and one, two-thousand and two, three- thousand and three'. If your vehicle's front bumper passes the point before you finish counting to three, you are following too close to the vehicle in front of you. Reduce your speed, and count to three again.

At which speed does the 3-second following distance method work?
Three seconds should allow for enough space when traffic is moving around 30 mph, but you may want to bump this to four seconds at 40 mph, five seconds at 50 mph, and so on. The faster a vehicle moves, the more time and space the driver needs to slow down and stop to avoid accidents.
