## What is the 3 to 6 second rule?

## What is the safest speed to drive?

A pedestrian has a 90 percent chance of survival if hit by a vehicle moving at 30 kmph (18.64 mph). This decreases to 70 percent at 40 kmph (24.85 mph) and less than 20 percent at 50kmph (31 mph). Driving at lower speeds also enables drivers to stop within a shorter distance.

## What is an easy way to know if you are maintaining the safe driving distance?

Safe Following DistanceLocate a fixed point ahead. … When the vehicle ahead of you passes that fixed point, count to yourself, “one thousand one, one thousand two, one thousand three.” If your vehicle passes the same fixed point when you say “one thousand three,” then you have a three-second safe following distance.More items…•

## How far does a car travel in 1 second?

Here’s some food for thought. At 55 mph, your vehicle is traveling at about 80 feet per second. Feet-per-second is determined by multiplying speed in miles-per-hour by 1.47 (55 mph x 1.47 = 80 feet per second.) With this in mind, let’s add the perception and reaction distance to the formula.

## What is the 4 second rule?

## How many car lengths is 2 seconds?

Remaining at least 2 seconds from the vehicle in front will provide a distance of one car length per 5 mph, at which ever speed you drive. The 2 second rule is used regardless of speed because the distance between your vehicle and the one in front will extend the faster you travel.

## How can I calculate my driving distance?

How do you calculate how far away you should be? Simple: pick a marker at the side of the road (e.g., lamppost, road sign, tree), and as soon as the motorcyclist ahead of you passes that point, count how many seconds it takes until you pass the same marker. If you don’t make it to three seconds, you’re too close!

## How far do u stop behind a car?

## How many car lengths is 3 seconds?

## What is the safe distance between two cars?
