When driving on slippery roads you should not use what?
D. Avoid crossing bridges or intersections. On slippery roads, you should increase your following distance. It may take more time to stop your vehicle than it would under normal conditions.
What should never be used when the road surfaces are wet or slippery?
Wet Road surfaces can cause the tires to hydroplane or ride up on a film of water starting at 35 mph which could cause lose of control. After 55 mph tires may leave the road surface.
When driving on the slippery roadway your following distance should be increased?
Three-second rule will need to increase when driving on low traction surfaces. The only exception to this is for drivers of large commercial vehicles who should use a minimum 4-second following distance in traffic.
What three factors affect the levels of traction when driving?
These are the main factors that affect traction while driving:
- The material the road surface is made from.
- The condition of the road.
- The condition of your tires.
- The weight of your vehicle.
- The balance of your vehicle.
Which is an example of driving too fast for conditions?
Braking in a curve can cause the wheels to lock up and the vehicle to skid. 16 An example of a driver traveling too fast for conditions is shown in the video clip below. Training exercise questions follow the video clip. If playback doesn’t begin shortly, try restarting your device.
What happens to braking distance as speed increases?
From this we can see that braking distance is proportional to the square of the speed—which means that it increases considerably as speed increases.
What’s the impact of reducing the speed of a car?
Reducing the impact speed from 60 to 50 kilometres/hour almost halves the likelihood of death, but has relatively little influence on the likelihood of injury, which remains close to 100 per cent.
How does frictional resistance affect the speed of a car?
The frictional resistance between the road and the car’s tyres is also important—a car with new tyres on a dry road will be less likely to skid and will stop more quickly than one with worn tyres on a wet road. If slope and frictional resistance are equal, the factor that has most influence on braking distance is initial speed.
Is it safe to drive under the speed limit?
Driving under the speed limit (under normal conditions) is a good safe-driving technique. To activate the Anti-lock Brake System, you must pump the brake three times. Most states require a driver to show a signal for at least 100 feet before making any change in direction.
Which is the safest speed on the road?
The safest speed to travel is the prevailing speed of traffic. a)Judgment, distance, and maximum car capabilities. b)Road, weather, and traffic conditions. c)Brakes, steering, and acceleration. d)BAC, DWI, or fatigue.
Why do traffic accidents increase in snowy conditions?
The reason traffic accidents increase during snowy, icy or foggy conditions is that… a)Drivers aren’t accustomed to these conditions. b)Roads aren’t adequately built for safe handling of these conditions. c)Accidents naturally increase during these conditions.
When is snow and ice the most slippery?
A Snow and ice are most slippery when the sun comes out and they begin to melt.
