Study Notes
Visibility & Hazard Response
- In reduced visibility, more effort is required to gather visual information, as responses to hazards take longer.
Maintaining Clear Windows
- In high humidity or rainy conditions, keep vehicle windows clear by using the defroster or air conditioner.
Sun Glare Management
- To reduce glare and eyestrain from bright sunlight, use sunglasses and the sun visor.
Night Driving Techniques
- To extend the IPDE (Identify, Predict, Decide, Execute) process at night, look beyond the headlight range.
- When no other vehicles are present at night, utilize high-beam headlights for better visibility.
Responding to Oncoming Traffic
- If an oncoming driver does not switch to low-beam headlights, slow down and glance at the right edge of the roadway to maintain orientation.
- Reduce glare from oncoming headlights by making quick glances ahead rather than staring directly into the light.
Fog and Visibility
- Headlights shining into fog reflect back light from water particles, reducing visibility.
- In heavy fog, to alert other drivers of your stationary position on the road, activate emergency flashers.
Rain and Driving Safety
- Use low-beam headlights in heavy rain to improve visibility.
- Roadways are slickest during the initial rainfall when water mixes with dirt and oils on the surface.
Hydroplaning
- Hydroplaning occurs when tires lose contact with the road, resulting in decreased control of the vehicle.
- If driving through deep water, apply light brake pressure to maintain control.
Winter Driving Precautions
- If windows ice up and traction becomes hazardous, it's advisable to avoid driving altogether.
- Bridge surfaces can freeze before adjacent roads due to cold air circulating above and below the surface.
Ice Awareness
- Black ice refers to thin, nearly invisible sheets of ice on the roadway.
- A front-wheel skid is identified when the vehicle tends to go straight despite steering input.
Skid Recovery Techniques
- If the rear of the vehicle skids to the right, counter-steering to the right helps regain control.
Braking Techniques
- Controlled braking involves manually applying brakes for efficient stopping.
High Wind Considerations
- Steering becomes more challenging in high-wind situations; maintain a firm grip on the wheel.
Engine Temperature Awareness
- If the vehicle's temperature light illuminates, turning off the air conditioner can assist in cooling the engine.
- Never remove a radiator cap from a hot engine to prevent scalding injuries from hot liquid.
Winter Driving Strategy
- Make a conscious effort to utilize the IPDE process when driving in winter conditions for enhanced safety.
Exhaust System Leaks
- A leak in the vehicle's exhaust system can lead to a dangerous buildup of carbon monoxide gas inside the cabin.
