As a point of reference, Lambeau Field is 360 feet long, end to end.

What is safe distance between cars?

two secondsTraffic researchers, employing sound scientific principles, have time and again focused on what is known as the ‘two-second rule’. This means that at any given point while driving, one should stay at least two seconds worth of stopping distance from the vehicle directly in front of you.

Calculating this rule is fairly simple. Basically, you should always allow three full seconds between yourself and the vehicle in front of you. … If your speed increases, the distance between your vehicle and the car in front of you also needs to increase in order to leave the three-second gap.

What is the formula of stopping distance?

Expressed in the formula: (speed ÷ 10) × (speed ÷ 10) + (speed ÷ 10 × 3). For my standard example at 100 km/h, the stopping distance under normal braking is 130 metres.

How many car lengths is 2 seconds?

The two-second rule is useful as it works at most speeds. It is equivalent to one vehicle- length for every 5 mph of the current speed, but drivers can find it difficult to estimate the correct distance from the car in front, let alone to remember the stopping distances that are required for a given speed.
