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

Certain vehicle light checks cannot be performed simultaneously; specifically, brake lights, flashers, and turn signals should be checked at different times for accuracy.
