What is safe stopping distance?
Keep at least 3 seconds’ distance between your vehicle and the vehicle in front of you. You should increase your crash avoidance space to 4 or more seconds when driving in poor conditions, such as on unsealed (dirt or gravel), icy or wet roads, or at night.
What is the stopping distance at 60 mph?
Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances.
How long does it take to stop a car at 88 mph?
(fps=1.467 * MPH). If the vehicle deceleration rate is 20 fpsps (rather than the previously calculated 15 fps), then stopping time = 88/20 = 4.4 seconds. Since there is a 1 second delay (driver reaction time) in hitting your brakes (both recognition and reaction time is often 2 seconds), the total time to stop is 5.4 seconds to 6.4 seconds.
How to calculate the distance of a car when braking?
To determine how far the vehicle will travel while braking, use the formula of 1/2 the initial velocity multiplied by the time required to stop. In this case, this works out to be .5 * 88 * 4.4 = 193.6 feet, plus a reaction time of either 88 feet for a second delay in reaction time, or 176 feet for two seconds reaction time.
What is the stopping distance in a car crash?
The stopping distance is very short because none of the colliding objects (including body and, e.g., windshield) are contractible enough. We can estimate it to be approximately 4 cm (you can change it in the advanced mode of this impact force calculator).
How many feet does a car have to stop before stopping?
Allow enough time to pass the commercial vehicle and return to the right lane before coming within ________ feet of approaching traffic. Commercial vehicles require greater stopping distance than cars. An average passenger car traveling at 55 mph can stop within _______ to _______ feet.

What’s the braking distance for Drive and stay alive?
(Copyright ©, Eddie Wren, and Drive and Stay Alive, Inc., 2003 onwards) Remember – 1: When the road is icy or covered with compacted snow, or diesel fuel has been spilled (which is a particular risk near certain gas stations) the ‘braking distance’ for your vehicle can be as much as ten times further than for dry roads/pavement.
