You should be 2-3 seconds behind a given point that the vehicle in front just passed.
At 65 mph, that is 95 feet per second, so multiply by 2 or 3 and you should be 190-280 feet behind
10-15 feet . You need to be 2 full seconds behind. Pick stationary object vehicle in front passes, then count how long until you pass the same object. Not 2 seconds? Increase you following distance! Another rule of thumb is to stay behind one car length for every 10 miles per hour, so at 35 mph you would want to be 3 and 1/2 cars behind the car in front of you.
When traveling at 55 miles per hour, a good rule of thumb for following distance is to maintain at least one second of distance for every 10 feet of your vehicle's length. Since your vehicle is 30 feet long, you should leave approximately 3 seconds of following distance. This allows for adequate reaction time and helps ensure safety on the road.
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
For nighttime driving in rain, it's advisable to add at least 2 seconds to your following distance due to reduced visibility and slick road conditions. In fog, you should add another 2 seconds, as fog significantly impairs visibility and reaction times. Therefore, for nighttime rain and fog combined, you should add a total of 4 seconds to your following distance.
one second for every ten feet of your vehicle length
You should always remain a safe distance when you are behind another vehicle. The recommended amount of space that you should leave is one and half car lengths.
The minimum following distance behind another vehicle that should be maintained is typically 3-4 seconds. This allows enough time to react in case the vehicle in front suddenly stops or slows down.
In California, the appropriate distance to stop behind another vehicle at a red traffic light is typically about one vehicle length or at least 3 to 5 feet behind the vehicle in front of you. This distance allows for safe maneuvering and visibility, particularly in case of emergencies. Additionally, drivers should ensure they can see the rear wheels of the vehicle ahead touching the pavement.
