What is intermediate risk driving?
Intermediate risk driving is the operation of a motor vehicle in a driving environment that includes controlled intersections and moderate traffic volume traveling less than 55 miles per hour.
How much following distance should you maintain between you and the vehicle in front of you quizlet?
How much space should you keep in front of you? One good rule says you need at least one second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and the vehicle ahead.
How many feet should you drive with?
Is two foot driving the answer? The basic idea is that by using two feet to drive — one for the accelerator and one for the brake — drivers will be less likely to use the wrong pedal by accident. Because you don’t need to maneuver your right foot back and forth, you reduce the chance of an inaccurate placement.
Which method is the most effective for calculating proper following distance?
The most reliable method drivers use to gauge this distance is by counting seconds. To do this, pick a stationary object on the side of the road, like a road sign or overpass, and, as soon as the vehicle in front passes your chosen object, begin counting: “one-one-thousand, two-one-thousand…”.
What following distance is recommended when traveling at speeds of 55 mph or faster?
At 55 mph, on a dry road with good brakes, your vehicle will skid approximately 170 feet more before stopping. This distance, combined with the perception and reaction distances, means you need about 300 feet to stop a car traveling at 55 mph.
Which three factors determine how long it takes to stop a vehicle?
Three factors determine the distance that it takes to stop your vehicle: perception time, reaction distance and braking distance. Perception time: The time it takes you to recognize a hazard. Reaction distance: The distance your vehicle travels between the time you recognize a problem and the time you apply the brakes.
What are three 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.
How do you use the 4 second rule?
The 4-second rule is used when it would take you longer to stop than usual. To check you’re travelling 4 seconds behind the vehicle in front, follow the same steps as the 2-second rule but count ‘one thousand and one, one thousand and two, one thousand and three, one thousand and four’ instead.
What is the 4 second rule and how do you we achieve it?
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 are the 4 factors that affect braking?
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.
When should you apply the 4 second rule?
You should apply the four-second rule when it’s wet, frosty or when you are towing a trailer. The four-second rule means that you leave four seconds between you and the vehicle in front. It gives you more time to react and more time to stop.
What is the correct way to adjust safety belts?
What is the correct way to adjust safety belts?…
- Adjust your seat to a comfortable upright position. Make sure your safety belt is not twisted.
- Snap the metal fitting on the end of the safety belt into the buckle.
- Finally, adjust the shoulder part of your safety belt across your chest.
What is a properly adjusted seat belt?
Position the belt low on your hips, then pull the loose end of the lap belt away from the buckle to adjust it tighter. Pull until there is no looseness in the belt, but not until it is causing an indent in your body. Seat belts are devices that has been proven to save lives.
What are some factors that affect energy of motion?
The factors that affect your energy of motion are speed and weight. The energy of motion increases proportionally with the increase in weight, and the energy increases proportionally with the square of the increase in speed.
When an object moves What is kinetic energy?
Kinetic energy is the energy of mass (an object) in motion (moving). The faster an object is moving, the more kinetic energy it has. Any object that is moving has kinetic energy – the moving object has energy because of its motion.
