The 4-6 second range is the space you will travel during the next 4-6 seconds. The area you can see clearly and sharply is seen with your central vision. The area you can see to the left and right of central vision is your side vision, or peripheral vision.
What skid occurs when a tire suddenly loses pressure?
Driver Ed: Chapter 13 – Natural Laws and Risk Management
|Power Skid||You step on the accelerator too hard and the car begins to skid.|

|Blowout Skid||tire suddenly loses air pressure, and the car begins to skid.|
What is impact distance in driving?
Distance between impact and stop ( force of impact) the shorter the distance, the greater the force of impact. How many collisions occur during an accident. 4: 1. vehicle hitting an object, 2.occupants hitting something inside the vehicle, 3.
What are some risk factors that could be contributed by the roadway?
Risk factors contributed by the roadway and the environment might include construction, sharp curve, snow and ice. The driving task is primarily a thinking task. When you apply the IPDE process, you may decide to change speed, change direction, or communicate with others.
What are the five rules of the Smith system?
The Key Five Rules of the Smith System:
- Aim High. The first rule for this method is “Aim high in steering”.
- The Big Picture. “Be aware of your surroundings at all times” may seem obvious to say, but distracted drivers are.
- Keep Your Eyes Moving.
- Leave Yourself an Out.
- Make Sure They See You.
What does IPDE stand for?
We use the IPDE (Identify, Predict, Decide, Execute) approach to driving to deal with potential and real hazards.
What causes tires to lose traction?
In winter, loss of traction can occur anytime, anywhere – when going too fast around a corner, when dry conditions quickly change to rain or ice, when parked incorrectly on an icy hill, or applying too much brake (causing the wheels to lock).
When a vehicle loses traction with the road the driver will lose control of?
Wet road surfaces can cause tires to hydroplane (skim on a thin layer of water). This could result in loss of control and steering ability. Hydroplaning is caused by a combination of standing water on the road, car speed, and under-inflated or worn-out tires.
What causes skidding on the road?
A skid happens when the tires lose their grip on the road, which can be caused one of four ways: Driving too fast for road conditions. Braking too hard and locking the wheels. Turning the wheels too sharply.
What is the most common mistake new drivers make?
Top 7 Mistakes New Drivers Make
- Speeding. Speeding is one of the biggest mistakes teens make behind the wheel.
- Texting and Driving.
- Not Being Attentive 100% of the Time.
- Impulsive Behavior.
- Not Wearing a Seatbelt.
- Adopting Their Parent’s Bad Habits While Driving.
- Not Adapting Their Driving Behavior to the Weather Conditions.
What are the 3 parts of stopping distance?
Stopping distance consists of three factors: Driver’s reaction time + Brake lag + Braking distance.
What are the 3 parts of total stopping distance?
Total Stopping Distance is the sum of the perception distance, reaction distance and braking distance.
What are 2 risks contributed by the roadway and environment?
Risk factors contributed by the roadway and the environment might include construction, sharp curve, snow, and ice.
What are the 4 characteristics of risk?
- Situational. Changes in a situation can result in new risks.
- Time-based. In this case, the probability of the risk occurring at the beginning of the project is very high (due to the unknown factor), and diminishes along as the project progresses.
- Magnitude Dependent.
Which of the following is part of the highway transport system?
The three parts of HTS are: people, vehicles, and roadways. So, the correct answer is choice.
What does all good kids love milk mean?
THE 5 KEYS TO SMITH SYSTEM DRIVING. Using the mnemonic “All good kids like milk” is a good way to remember the “A,” “G,” “K,” “L” and “M” of Smith’s 5 Keys: Aim High in Steering. ®
What is 15 second eye lead time?
Eye lead time is how far ahead of their vehicle drivers scan. On the highway, eye lead time should be 20 to 30 seconds
at 100 km/hr that’s at least 500 metres. In the city, it should be 12 to 15 seconds or about 1½ to 2 city blocks.
What are the 3 parts of the Smith System?
Each of the Smith5Keys and all knowledge derived from “The Smith System,” (Space-Visibility-Time) “Space Cushion Driving,” (G.O.A.L.), are registered, copyrighted and trademarked by Smith System for the use of Smith System Driver Safety Training.
What is IPDE in driving?
IPDE stands for Identify, Predict, Decide, and Execute. This strategy also should be used in off-road driving. Identify any objects or conditions that may cause you trouble while driving. Predict what results might occur when you encounter the object or condition.
What is meant by driving defensively?
Defensive driving means protecting yourself from more than just other drivers. It’s about thinking ahead and anticipating hazards so you can avoid accidents before they happen.
How does IPDE help reduce risk on the roadway?
You first minimize a hazard by putting space between yourself and the hazard. You separate hazards by adjusting your speed to deal with one hazard at a time. You compromise space by giving more space to the greater hazard.
How do overinflated and underinflated tires affect traction?
Proper air pressure in a tire helps to distribute the weight of a vehicle evenly across the tire’s tread pattern, so the tire (and the vehicle) is at its most stable. When a tire is under-inflated or over-inflated, it loses stability, negatively affecting handling, cornering, and stopping.
What are 3 factors that can cause a loss of traction?
The causes of skidding (loss of traction) can be divided into three groups: (1) conditions of the road, (2) conditions of the vehicle, and (3) actions of the driver. Ice, snow, or frost.
What is rear wheel loss of traction called?
Rear wheel loss of traction, termed oversteer, occurs when rolling traction moves to sliding traction on the rear wheels of the vehicle.
When tires lose all or part of their grip on the roadway when braking accelerating or steering?
A skid may happen when one or more tyres lose their grip with the road’s surface. Road conditions can have an impact on whether or not a vehicle skids: Ice, snow, or frost.
What is the term for when tires lose their grip on the road traction sliding skating skiing?
Skid. A skid results when a vehicle loses part or all of its grip on the road.
What affects traction while driving?
Traction between your car’s tires and the surface of the road will be significantly reduced when the roadway is smooth, wet or slick due to environmental conditions. Rain, snow &
ice, mud, wet leaves and chemical residue from vehicles are some of the worst traction-reducing substances.
What happens during a front-wheel skid?
Front-wheel skids are often caused by hard braking or acceleration in a front-wheel drive vehicle. When the front wheels lose traction, you will not be able to steer. Sometimes front-wheel skids are perceived as more dangerous because they are experienced less often.
When the skid occurs between road pavement and tyre?
In the case of car the centripetal force is provided by friction force. If the maximum friction provided by the ground and the tires is less than the required centripetal force then it will not be able to take a perfect turn as expected and it will try to leave out the circle i.e. it will skid away.
What is the leading cause of skids?
The most common driver-induced causes of skids are over-steering, over-braking, over-accelerating or driving too quickly. Inexperienced drivers might be especially prone to over-steering, but this problem can happen to anyone.
