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 components make up total stopping distance quizlet?

made up of three components: Human-perception distance, Human-reaction distance, Vehicle-Braking distance. All three components factor in how long it takes to come to a complete stop.

What is the total stopping distance?

Total stopping distance is the distance your vehicle travels from the time you see a hazard and press on the brake until the vehicle stops.

What are three factors of total stopping distance with hydraulic brakes?

what are three factors that add up to total stopping distance with hydraulic brakes? perception distance, reaction distance, braking distance.

What is total stopping time made up of?

Total stopping time is made up of: all the above are correct (reaction, braking, and perception time).

What factors can influence your stopping distance quizlet?

  • 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 factors affect your 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.

How is braking distance defined in the module?

Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. … The other component is the reaction distance, which is the product of the speed and the perception-reaction time of the driver/rider.

What does reaction distance consist of?

Reaction distance is the distance traveled between the moment you mentally perceive a hazard and the moment you physically hit the brakes.

What does your stopping distance depend on?

Explanation Stopping distance depends on several different factors. It depends on the conditions of the road, the vehicle’s brakes, and the tires, as well as the amount of time it takes for a driver to recognize the need to stop.

What is a critical factor when judging stopping distance?

Of the two, reaction time is the critical factor in determining the distance it takes to stop your vehicle. The more quickly you can perceive a problem and react to it, especially at higher speeds, the better your chances are of avoiding a collision.

What is the total stopping distance quizlet?

Terms in this set (9) Stopping distance is the total distance travelled from the point the driver first sees a reason to stop to when the vehicle actually stops. Thinking distance is the distance travelled between the moment you first see a reason to stop to the moment you use the brake.

How do you calculate total stopping distance?

Total stopping distance is a combination of Reaction Distance, Perception Distance, and Braking Distance. Perception and Reaction time each add 55 feet (110 feet total) to your total stopping distance.

What are the two types of braking system?

There are two kinds of service brakes, or the brakes that stop your vehicle while driving: disc and drum brakes.

What is the total stopping distance at a speed of 60 mph?

What impact does total stopping distance have on speed for freeway driving?

Total stopping distance in feet at various speeds (mph), by the time (distance) it takes the driver to react plus the braking distance. The driver takes the same amount of time to react regardless of speed. As speed doubles, stopping distance quadruples.

What forces affect stopping distance?

The braking distance of a vehicle can be affected by: poor road and weather conditions, such as wet or icy roads. poor vehicle conditions, such as worn brakes or worn tyres.

What are the 3 levels of braking that precede the need to lock up your wheels?

  • coasting (take foot off gas)
  • threshold/controlled.
  • emergency straight-line.

What are 5 factors that affect stopping distance?

  • The total weight of the truck and its load.
  • The length and steepness of the downhill grade.
  • The weather and road conditions.

What are the 3 factors that affect your vehicle in a curve?

Your vehicle’s speed, the sharpness of the curve, the bank of the curve, and your vehicle’s load will affect the control you have in a curve. Speed You have no control over how sharp a curve is, but you can adjust your speed. To reduce your chance of skidding, lower your speed before entering a curve.

What are 3 factors that will change your vehicle's force of impact in a collision?

Three factors which will change your vehicle’s force impact in a collision are: speed, weight and the distance between impact and stopping.

What are the 2 components of an expressway that allows car to exit the road?

The exit has two components: Deceleration lane – area where speed can be reduced to exit safely • Exit ramp – these may be level or sharply curved, uphill or downhill. Be sure to adjust speed for ramp speed limit.

Are braking and stopping distance the same?

Braking distance is how far your car travels from the time the brakes are applied until it comes to a complete stop. Total stopping distance is the combined distance of reaction distance and braking distance.

How do you calculate braking and 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.

What are two important things about stopping distance?

These first 2 components of stopping distance are human factors and as such can be effected by tiredness, alcohol, fatigue and concentration levels. A perception and reaction time of 3 or 4 seconds is possible. 4 seconds at 100 km/hr means the car travels 110 metres before the brakes are applied.

What are the three basic steps in the NSC collision prevention formula?

  • Recognize the hazards: Continuously scan the road ahead and behind checking your mirror every 3 to 5 seconds.
  • Understand the defense: Continuously scan the road for possible hazards.

What is the stopping distance on a dry road at 50 mph?

Answer: Overall stopping distance at 50mph is 175 feet (see above).
