Driving too fast is a significant cause of deadly crashes. You must adjust your speed depending upon driving conditions. These encompass traction, curves, visibility, traffic and hills.

You are watching: When driving 55 mph.how many feet does it take for your vehicle to come to a complete stop?

Speed and Stopping street

Three things include up to total stopping distance:

Perception Distance+ Reaction Distance+ Braking Distance--------------------------= complete Stopping Distance

Whenever you double your speed, that takes around four time as much distance come stop, and also your auto will have four time the devastating power if the crashes. High speeds rise stopping ranges greatly. By slowing down a little, you can get a lot in lessened braking distance.

Effect of automobile Weight on avoiding Distance

The heavier the vehicle, the much more work the brakes need to do to avoid it and the more heat lock absorb. However the brakes, tires, springs and also shock absorbers on heavy vehicles space designed come work best when the auto is fully loaded. Empty trucks need greater preventing distances, due to the fact that an empty car has less traction. It deserve to bounce and lock up its wheels, giving much poorer braking. (This is not generally the situation with buses.)

You cannot steer or brake a auto unless you have actually traction. Traction is friction in between the tires and also the road. There are some road problems that reduce traction and call for lower speeds.

the is very important the you memorize the listed below stopping street formula and memorize the the meaning, time, and distance of each term in the formula. This will very likely present up ~ above your composed exam!
Be certain you mental this together the created exam frequently asks just how much much longer it takes to stop once you double your speed.
Yes, it"s true! empty trucks take much longer to protect against than totally loaded trucks. The written exam often asks about this for this reason make sure you mental that.

The distance your auto travels from the time your eyes check out a risk until your mind recognizes it defines which of the adhering to terms:

Perception street is the street your vehicle travels from the time your eyes see a danger until your mind recognizes it. The tardy time because that an alarm driver is around 3/4 second. In ~ 55 mph, you take trip 60 feet in 3/4 second.

Take a moment to memorize the meaning for perception Distance. This will really likely present up on your written exam.

At 55mph on dry pavement with good brakes, it can take a heavy vehicle around how countless feet to stop once the brakes room applied?

Make certain you memorize the definition of Braking Distance and the time and distance the takes because that a car to stop once the brakes are fully applied.

The distance traveled from the time your brain recognizes the risk until her foot physically access time the brakes specifies which that the following:

Reaction street is the distance traveled from the moment your brain tells her foot to move from the accelerator till your foot is actually pushing the brake pedal. The mean driver has actually a reaction time that 3/4 second. This accounts for an additional 60 feet traveled at 55 mph.
