Study Notes
Dangerous Situations
- Wet brakes during rain can lead to hydroplaning, excessive brake wear, or trailer jackknife incidents.
- Crossing railroad tracks on dirt roads may result in getting hung up halfway, unstable ground, or sinking tires.
Cargo Loading Guidelines
- Maintaining a balanced load in the cargo area is crucial for stability.
- Containerized loads are typically used for freight transported partway by rail or ship and come with specific tie-down devices.
Federal Regulations and Inspections
- Federal inspectors have the authority to inspect trucks or buses and can place vehicles out of service if necessary.
- Knowledge of HAZMAT regulations does not require basic chemistry but includes understanding when to use placards and which products can be loaded together.
Safe Driving Practices
- When driving on grades, choose a speed that is safe based on the vehicle and its cargo, within posted limits.
- Schedule driving hours during times when you are normally awake to ensure alertness.
Health and Medication Concerns
- It is essential to consult a doctor about any prescribed medication that may affect driving ability.
Vehicle Control Techniques
- Avoid using stab braking on vehicles equipped with anti-lock brakes to maintain better control.
Accident Scene Protocol
- In the absence of a CB radio, protect the accident scene as the first step when arriving at an accident site.
Tire and Weather Considerations
- Ensure tires have adequate tread, with at least 4/32 inch in cold weather, to maintain traction for steering and moving through snow.
Awareness While Driving
- While passing other road users, assume they may move into your lane unexpectedly.
Running Vehicle Light Checks
