1 . Stopping distance can be affected by:
Traffic.
Factors that can affect stopping distance include your vehicle's speed, its weight, and the traction provided by the road surface.
2 . In very hot weather, the air pressure in tires may decrease.
Air expands as its temperature increases, so air pressure in your tires is likely to increase when you are driving in very hot weather. Under such conditions, stop periodically to ensure that your tires are not at risk of blowing out or catching fire.
3 . When driving in fog, you should:
Use the heater.
If you must drive in fog, you should use your low beam headlights and fog lights to maximize your visibility. Using high beam lights will only make it more difficult for you to see.
4 . A driver should always:
Travel faster than the speed limit.
When driving, you should always scan the road for potential hazards. Formulate plans for how to deal with the hazards if they develop into emergencies.
5 . When carrying a wide load, a driver should:
Drive on the shoulder.
Loads that are over-length, over-width, or overweight require special permits and may be subject to restrictions, such as being allowed on the road only at certain times of the day.
6 . Air tank drains should:
Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Manually operated air tank drains must be opened daily to remove this build-up.
7 . While driving, you should:
Focus on your own driving and not worry about other drivers.
