Study Notes
General Safety and Regulations
- Warning devices should be placed 10, 100, and 200 feet from approaching traffic when stopping on a one-way road or divided highway.
- Inspect wheel bearing seals for leaks to ensure vehicle safety.
- A tire failure should not be treated by braking hard; instead, maintain control and gradually slow down.
- Hazardous materials placards notify others of the cargo’s hazard class.
- Federal law mandates drug and alcohol testing for commercial drivers, with positive results reported to the Division of Motor Vehicles.
Vehicle Operation and Control
- Doubling your speed increases stopping distance by four times.
- A 20-foot load requires at least 2 tie-downs for secure transport.
- Downshifting is recommended when starting downhill or entering a curve for better control.
- Empty trucks do not have optimal braking distance; loaded trucks provide better stability.
Driving Conditions and Emergency Situations
- Always back towards the driver’s side for better visibility.
- Visibility at night is improved by using high beams when safe.
- In case of drowsiness while driving, pull off the road to rest.
- If an aggressive driver confronts you, seek safety rather than engaging.
Cargo and Load Management
- Covering cargo keeps it safe and complies with state regulations.
- Regularly check cargo within the first 50 miles, then every three hours or after breaks.
- Ensure loads do not exceed gross weight or axle weight limits before transport.
Vehicle Maintenance and Safety Features
- Common causes of flat tires include under-inflation. Minimum tread depth for front tires is 4/32 inch.
- An antilock braking system (ABS) prevents wheels from locking during hard braking, enhancing vehicle safety.
- For safe operations, keep the starter switch key with you during pre-trip inspections to prevent unauthorized use.
Following Distance and Reaction Time
- Maintain a four-second following distance at 55 mph in a 30-foot vehicle.
- Total stopping distance is the sum of perception distance, reaction distance, and braking distance.
Fire and Accident Prevention
- Common vehicle fire causes include shore circuits and loose connections; take precautions.
- Set up warning devices at accident scenes to prevent additional accidents.
Other Important Points
- When temperature drops to freezing, shaded areas and bridges freeze first, creating hazardous conditions.
- Avoid medications that induce drowsiness, and plan trips to be completed during daylight.
- Utilize visual cues, like shadows or landmarks, to determine following distance effectively.
Legal Responsibilities
- Notify your employer of any traffic violation, excluding parking, within 30 days.
- Having more than one driver's license incurs a minimum $250 fine for the first offense.
