What are the 3 parts that make up total stopping distance?
Stopping distance consists of three factors: Driver’s reaction time + Brake lag + Braking distance.
What three things add up to total stopping distance quizlet?
What three things add up to total stopping distance? Perception Distance + Reaction Distance + Braking Distance.
What three factors add up to the total stopping distance for a commercial motor vehicle?
Total stopping distance is made up of three parts: Perception Distance – The distance a vehicle travels while a driver is identifying, predicting and deciding to slow down for a hazard. Reaction Time – The time it takes for a driver to execute a decision once a danger is recognized.
Which 3 factors determine the time and distance it takes to stop a vehicle?
Three factors determine the time and distance it takes to stop….On this page:
- Perception time.
- Reaction time.
- Braking time.
- Braking.
What are 5 influencing factors of stopping distances?
10 things that can affect your stopping distance
- Speed. Your stopping distance is actually made up of two factors – thinking distance and braking distance.
- Brakes.
- Tyre Pressure.
- Tyre Wear.
- Tyre Quality.
- Road Conditions.
- View of the Road.
- Distractions.
What does not affect stopping distance?
Field of View – Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you hit the brake pedal.
What do stopping distances depend on?
After the driver applies the brakes, the time it takes to stop depends on a number of factors such as brake quality, tire tread, and road conditions. However, stopping distance depends most on the speed of the vehicle. The higher the vehicle’s speed, the higher its kinetic energy, a form of mechanical energy.
What are the factors that affect stopping distance?
4 Factors That Can Affect Your 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.
How do I calculate stopping distance?
How to calculate stopping distance
- 20 mph x 2 = 40 feet (12 metres or 3 car lengths)
- 30 mph x 2.5 = 75 feet (23 metres or 6 car lengths)
- 40 mph x 3 = 120 feet (36.5 metres or 9 car lengths)
- 50 mph x 3.5 = 175 feet (53 metres or 13 car lengths)
- 60 mph x 4 = 240 feet (73 metres or 18 car lengths)
What are the four factors that affect braking distance?
Braking distance
- poor road and weather conditions, such as wet or icy roads.
- poor vehicle conditions, such as worn brakes or worn tyres.
- a greater speed.
- the car’s mass – more mass means a greater braking distance.
What are the 6 factors that affect braking distance?
Terms in this set (7)
- Speed. The higher your speed, the longer your braking distance.
- Vehicle condition. A vehicle with worn tires, shock absorbers, or brakes needs a longer distance to stop.
- Roadway surface.
- Driver ability.
- Antilock Braking System (ABS)
- Hills.
- Loads.
What is the most important factor in accidents?
Personnel error (human factors) is the most common cause of both incidents and accidents. CFIT and loss-of-control accidents, which almost by definition involve human factors, account for more than half of all fatal accidents.
What are 7 factors that affect stopping distance?
The last factor than determines the total stopping distance is the cars braking capability which depends on factors such as;
- the type of braking system,
- brake pad material,
- brake alignment,
- tyre pressures,
- tyre tread and grip,
- vehicle weight,
- suspension system,
- the co-efficient of friction of the road surface,
What is meant by stopping distance?
: the distance that a driver needs in order to safely bring a vehicle to a complete stop.
How can I increase my thinking distance?
Longer reaction times increase the thinking distance when stopping from a given speed. There are different ways to measure reaction times. One simple method involves dropping a ruler between someone’s open thumb and forefinger.
How do you use the four second rule?
You can be held liable in an accident. 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 can affect thinking distance?
The thinking distance depends on the reaction time of the driver which could be affected by drugs, alcohol, distractions and tiredness. This distance will also be affected by the car’s speed.
Does fog increase thinking distance?
If you pass the same marker before you’ve finished counting, you should drop further back. It’s worth remembering that fog is moisture, so as well as hanging in the air, it will have coated the road surface in a wet layer which in turn will increase stopping distances further.
