Study Notes
Headlight Usage
- High beam headlights illuminate the roadway, reaching 500 to 1800 feet.
- Dirt on headlight lenses can reduce light output by up to 90%.
- Low beam headlights should be utilized in adverse weather conditions like fog, heavy rain, sleet, snow, or dust.
Driving Techniques
- Overdriving headlights prevents stopping within the visible distance ahead.
- Avoid looking directly at oncoming headlights; instead, glance to the right side of the road.
- When encountering fog, reduce speed, activate low beams, and use windshield defroster or air conditioning.
- Sudden directional changes are dangerous, especially on loose gravel or at high speeds.
Vehicle Maintenance
- Maintain a coolant ratio of 50% coolant and 50% water.
- Oil serves to lubricate the engine and helps in cooling.
- During cold weather, keep at least half a tank of gas to prevent fuel line freeze.
- Regularly monitor tire pressure during hot weather.
Skidding and Traction
- Front-wheel skids may occur due to hard braking or acceleration.
- On slippery, flat curves, maintaining traction becomes difficult.
- If a vehicle starts to skid, release the accelerator or brakes.
- Hydroplaning happens when driving too fast in wet weather, where tires lose contact with the road.
Collision Avoidance
- Two main types of skids are oversteering (fishtailing) and understeering (plowing).
- Use threshold braking by applying firm, steady pressure to avoid lockup.
- It is safest to brake when avoiding a collision, provided there’s enough space.
- If necessary, steer right or stop quickly if another vehicle is in the left lane.
Weather Conditions
- Virginia law mandates headlight use during inclement weather or when windshield wipers are active.
- In fog, avoid high beams as they can cause glare; only low beams should be used.
- Nearly 50% of flash flooding fatalities are related to vehicles, stressing the importance of vehicle awareness during storms.
Nighttime Driving
- At night, drivers should increase following distance compared to daytime driving.
- The sight distance rule dictates that one must be able to stop within the distance they can see.
Handling Snow and Hydroplaning
- In snowy conditions, if leaving the highway is not feasible, stop beyond the guardrail and stay informed about weather conditions.
- Vehicles can float, and even minor water on the road can affect control, necessitating cautious driving practices.
