Study Notes
Intersections and Traffic Control
- Intersections are points where roads meet or cross.
- Most intersections use traffic control devices to regulate flow.
- Assume that drivers may not follow right-of-way rules at four-way stops.
- Always scan all four corners before entering any intersection to ensure a clear path.
- Slow down at railroad crossings to assess safety.
Railroad Crossings
- A crossing with no lights flashing may still be unsafe without looking first.
- Never stop on railroad tracks unless the vehicle ahead has stopped.
- Immediately check for trains if your car stalls on tracks; leave if a train approaches.
Collision Statistics
- Approximately 2.8 million crashes occur annually at intersections in America.
- Side impact collisions claim more than one-third of auto deaths.
- Complex intersections are prone to a high number of collisions, with nearly 1 million annually.
Roundabouts
- Roundabouts require drivers to slow down and yield to existing traffic before entering.
- Traffic always moves counterclockwise in roundabouts.
- Maintain a speed of 20 mph or less unless posted otherwise.
Vehicle Dynamics
- Traction is vital for vehicles navigating roads, influenced by weight and speed.
- Light trucks typically weigh more than standard cars.
- Larger vehicles like trucks can take more distance to stop compared to smaller vehicles.
Driving Challenges
- Visibility challenges include motorcycles being hard to spot, especially from behind.
- Drivers of pickups and SUVs tend to see farther ahead, but higher headlights may cause glare.
- The perception, reaction, and braking distances collectively determine total stopping distance.
Weather and Road Conditions
- First 15 minutes of rainfall create the slickest road conditions; take extra caution.
- Reduce speed and increase following distances in adverse conditions, such as fog or snow.
- Avoid making rapid changes in speed to help prevent skids.
Safety and Responsibility
- All vehicles must yield to pedestrians in crosswalks.
- Pedestrians should always be attentive to vehicles and follow designated crossing rules.
- When driving near cyclists, maintain a safe following distance.
Headlight Usage
- Use low beam headlights in fog and high beam headlights only when appropriate to maximize visibility.
- Increase following distance at night to enhance reaction time to potential hazards.
Additional Terms
- Centripetal Force: Driving force that keeps an object moving in a circular path.
- Inertia: Object's resistance to changes in motion, relevant in vehicle handling.
- Hydroplaning: Occurs when tires lose contact with the road due to water, increasing the risk of loss of control.
