Stopping distance =

reaction distance + braking distance

.

In normal and dry conditions a driver should keep

2 to 3 seconds distance from the vehicle in front

. … In wet or slippery conditions a driver should keep 4 to 5 seconds distance from the vehicle in front.

Stopping distance: The average stopping distances should be

multiplied by 2 for stopping

distances in the rain and multiplied by 10 for stopping distances on ice.

when conducting the 60-0 mph stops using the 18” Michelin all season tire and as low as 126 feet with all tires currently available.

What is the overall stopping distance at 20 miles per hour?

At 20 mph during perception and reaction time, a vehicle will travel 45 feet (30 feet per second x 1.5 seconds). Once the brakes are applied, it takes approximately 19 feet to come to a stop, for a total distance of

What is the 3/4 second rule in driving?

Simply

leave 3 seconds worth of room between you and the vehicle you are following

. Just watch the vehicle in front of you pass a road sign or other inanimate object on the side of the road and count out “One Massachusetts, Two Massachusetts, Three Massachusetts” before your vehicle passes that same object.

What are the 4 factors involved in stopping distance?

  • Speed. The time it would take you to come to a halt isn’t just calculated by the time it takes you to press your brake pedal.
  • View of the Road. Bad weather will affect the ability of your tyres to grip the road sufficiently.
  • Weather. …
  • Tread.

What is the typical stopping distance for a vehicle in wet weather?

Speed Thinking Distance Braking Distance 50 mph 50 feet (15 m) 250 feet 60 mph 60 feet (18 m) 360 feet 70 mph 70 feet (21 m)

490 feet
80 mph 80 feet (24 m) 640 feet

What is the 4 second rule?

Once the vehicle ahead of you passes the object, slowly count to four:

“One one-thousand, two one-thousand

…” If you reach the object before you’re done counting, you’re following too closely. It’s a handy rule — however, it only holds true in good weather.

What type of road surface will increase your stopping distance by 10 times?

What type of road surface will increase your stopping distance by 10 times?

If the road is wet or icy

, this will significantly increase braking distances. Double the gap between your car and the car in front when it’s wet. Leave an even bigger gap if it’s icy – some advice says 10 times bigger.
