Study Notes
Vehicle Safety and Inspection
- Inspecting the vehicle before driving is crucial for ensuring safety on the road.
- Front tires must have a tread depth of at least 4/32 inches to maintain grip.
- All other tires require a minimum tread depth of 2/32 inches.
Emergency Equipment
- Essential emergency equipment includes a fire extinguisher, three reflective triangles, and spare fuses.
Cargo Inspection
- Inspect cargo within the first 50 miles of a trip and then every 150 miles or every three hours.
Backing Up Safely
- It is recommended to back up from the driver's side for better visibility.
- Use hand signals to communicate with a helper when backing up, emphasizing the importance of the "stop" signal.
Shifting Gears
- Key indicators for shifting gears include monitoring engine speed (RPM) and road speed (MPH).
- A tachometer should be observed for engine speed when shifting upward.
- Shift gears before approaching downgrades or curves to maintain control.
Retarders and Braking
- Retarders assist in reducing brake usage, enhancing safety.
- Good drivers scan the road 12 to 15 seconds ahead, or approximately 1/4 mile on highways.
Distance Awareness
- Stay vigilant for traffic and poor road conditions when looking ahead.
- Reflective triangles must be placed correctly: 10 feet, 100 feet, and 200 feet behind on one-way roads, and within 10 feet in front or behind on two-way roads.
Stopping Distance
- Total stopping distance comprises perception distance, reaction distance, and braking distance.
- For vehicles under 40 mph, allow 1 second for each 10 feet of length; for speeds above 40 mph, add 1 additional second.
Hazard Awareness
- Hazards include any condition that compromises safe driving, such as work zones, drop-offs, foreign objects, and ramps.
- Always have a plan when approaching hazardous road conditions.
Emergency Braking
- In an emergency, avoid braking until the vehicle speed is below 20 mph to maintain control.
- Brake quickly yet carefully to keep the vehicle moving in a straight line.
- Controlled braking and stab braking are the safest techniques for emergency stopping.
Tire Failure Response
- In the event of a tire failure, hold the steering wheel firmly, refrain from braking immediately, and inspect the tires once stopped.
