Reduced Visibility Driving

Driving conditions where it's harder to see, causing longer response times to hazards.

Clear Windows

Use the defroster or air conditioner to keep vehicle windows clear in high humidity or rain.

Sun Glare Management

Use sunglasses and sun visors to reduce eyestrain from bright sunlight.

Nighttime Driving Techniques

Look beyond headlights to give yourself more time to react during night driving.

Study Notes

Reduced Visibility Conditions

  • In reduced visibility, increased effort is required to gather visual information, leading to a longer response time to hazards.

Maintaining Clear Windows

  • To keep vehicle windows clear in high humidity or rainy conditions, employ the defroster or air conditioner.

Sun Glare Management

  • Using sunglasses and the sun visor helps reduce glare and decrease eyestrain when driving into bright sunlight.

Night Driving Techniques

  • Look beyond the headlights’ range to allow more time for the IPDE (Identify, Predict, Decide, Execute) process during nighttime driving.
  • Use high beam headlights when driving at night without other vehicles present.

Handling Oncoming Traffic

  • If an oncoming driver does not switch to low beam headlights, slow down and focus your gaze on the right edge of the road.
  • To minimize glare from oncoming headlights, frequently glance ahead while driving at night.

Fog Driving Tips

  • Headlights will reflect light back from fog due to water particles; this can impair visibility.
  • When stopped on the shoulder in heavy fog, activate emergency flashers to alert other drivers.

Rain and Snow Driving

  • In heavy rain, use low beam headlights to improve visibility.
  • Reduce speed and utilize low beam headlights when driving in snowy conditions.
  • Rain initially makes roadways slickest right as it starts to fall.

Hydroplaning and Water Safety

  • Hydroplaning occurs when tire contact with the road is lost due to water.
  • When driving through deep water, apply light brake pressure to maintain control.

Icy Conditions Awareness

  • Avoid driving if window icing creates hazardous traction conditions.
  • Bridge surfaces can freeze faster than nearby roads because cold air circulates above and below them.
  • Black ice is particularly dangerous as it consists of thin, nearly invisible layers of ice.

Skid Recovery

  • A front-wheel skid results in a vehicle going straight rather than turning.
  • If the rear of the vehicle skids to the right, steer in the direction of the skid (to the right).

Braking Techniques

  • Controlled braking involves applying brakes manually for prompt stops.

High Wind Conditions

  • Steering becomes challenging during high wind situations, requiring heightened awareness.

Engine Overheating Precautions

  • If the engine temperature light activates, turning off the air conditioner can help cool the engine.
  • Never remove a radiator cap from a hot engine to avoid burns from escaping hot liquid.

Extra Vigilance in Winter

  • Increased diligence in the IPDE process is crucial when driving in winter conditions.

Carbon Monoxide Hazard

  • A leak in the vehicle's exhaust system may lead to dangerous carbon monoxide buildup, posing health risks.
