Study Notes
Headlights and Weather Conditions
- Headlights must be activated when windshield wipers are used, regardless of visibility.
- Daytime running lights alone are insufficient; taillights must also be on.
- Fines for non-compliance can reach $100 with fees.
Wet Roadways
- Initial 10-15 minutes of rain make roads extremely slippery due to oil rising from asphalt.
- Conditions worsen in high heat as more oil surfaces.
- Beware of shaded road areas in cold weather; they freeze quickly and dry slowly.
Hydroplaning
- Occurs when tires lose grip and glide on water.
- Can happen at speeds as low as 35 mph with just 1/10 inch of water.
- Worn tires increase the risk; driving slower reduces the chance of hydroplaning.
Fishtailing
- Describes a situation where the rear of the vehicle sways back and forth unpredictably.
Night Driving Risks
- Highest rates of car crashes occur during nighttime.
- Serious accidents often happen in twilight or darkness.
- Traffic fatality rates are three to four times greater at night compared to daytime.
Overdriving Headlights
- Leads to dangerous situations if driving too fast to stop within the beam's range.
- Pennsylvania law requires low beams at 500 feet from oncoming vehicles and 300 feet when following another vehicle.
Night Driving Requirements for Learner's Permit
- New drivers can't drive from 11 p.m. to 5 a.m., except for employment or volunteer work with documentation.
- Must complete at least 65 hours of driving practice, including a minimum of 10 hours at night.
High Beams Usage
- Switch from high beams to low beams when another vehicle approaches to avoid blinding the other driver and impairing visibility.
Dashboard Warning Signs
- Steering failure is indicated by a yellow steering wheel symbol.
- Brake failure is alerted by ABS light.
- Check engine issues are highlighted by the engine warning light.
Types of Vehicle Failures
- Tire failures can occur suddenly; sounds may precede a blowout.
- Brake failures mean difficulties in stopping; a warning light may indicate partial braking still available.
- Total steering failure is rare but serious; use your horn and hazard lights, and stop safely if it occurs.
Tire Blowouts
- Front tire blowouts lead to steering wheel vibrations and vehicle pulling to one side.
- Rear tire blowouts may cause one corner to drop and result in a back-and-forth wobble.
Sticking Accelerator
- In an event of a stuck accelerator, maintain control and safety by not panicking but following emergency procedures.
