Study Notes
General CDL Knowledge
- Medical certification is required to be carried by drivers on interstate journeys.
- Serious traffic violations can result in CDL suspension: two violations lead to a minimum 60-day suspension, while three violations result in at least 120 days.
- A conviction for drunk driving twice results in a lifetime loss of CDL.
Vehicle Safety and Inspection
- Rust on wheels may indicate loose lug nuts, necessitating inspection.
- The suspension system supports the vehicle's load and keeps axles in place.
- Vehicle inspections ensure safety and can place vehicles out of service if deemed unsafely mechanical.
- Pre-trip inspections are conducted to identify potential issues that could lead to crashes or breakdowns.
Tire and Braking Regulations
- Front tire tread depth should be at least 2/32".
- Poor tire conditions can pose serious risks, including skidding or rolling over.
- Braking distance increases significantly with speed; stopping from 30 mph takes about 100 feet, while at 60 mph, it requires approximately 400 feet.
Driving Techniques
- Safe driving practices include turning on lights in low visibility and indicating intentions with signals for lane changes.
- Manage the space around the vehicle to avoid emergencies; maintain a following distance of about 4 seconds behind other vehicles.
- Strategies such as down-shifting before curves and using proper steering techniques enhance safety in turns.
Emergency and Hazard Awareness
- Stay vigilant for hazards early to act promptly; sudden changes can cause crashes.
- Use 4-way flashers or brake lights in work zones to alert following drivers of your presence.
- Vehicle emergencies frequently occur when critical components fail, emphasizing the importance of regular maintenance.
Weather and Road Conditions
- Hydroplaning can begin at 30 mph; tire pressure and tread depth are crucial for safety.
- Roads are most slippery shortly after rain begins and when black ice forms during freezing temperatures.
- Drivers must slow down in fog or poor lighting conditions, adjusting headlight usage appropriately.
Cargo Safety and Weight Management
- All vehicles must carry a fire extinguisher, spare electrical fuses, and tire chains.
- Drivers are held responsible for the vehicle's gross weight and ensuring cargo is secured to prevent shifting during transport.
- Blocking techniques can be employed to keep cargo in place, maintaining safe loading conditions.
Laws and Regulations
- Driving laws prohibit operating a vehicle under the influence of drugs that cause drowsiness.
- Regular load inspections occur within 25 miles of starting a trip, every change in duty status, and every 3 hours or 150 miles.
Fire Safety
- Fire safety protocol requires parking in open areas if a vehicle catches fire and using the proper type of extinguisher for specific fire classes (B:C for electrical and liquid fires).
- Water can be effective against tire fires, but care must be taken with other types of fires.
Night Driving
- Low beam headlights provide a safe visibility range of approximately 250 feet, while high beams extend visibility to 350-500 feet. Use appropriate lights based on conditions.
Additional Considerations
- Utilize proper hand signals when backing up with assistance.
- Drowsiness while driving necessitates resting rather than relying on stimulants.
- Understanding and executing safe clutch usage when shifting gears is essential for control.
