    Study Notes

    Vehicle Inspection and Safety

    • Safety inspection of vehicles is required to prevent breakdowns and crashes.
    • Federal and state laws mandate vehicle inspections, assessing safety before road use.
    • Essential components to check include gauges, tires, brakes, lights, electrical connections, and cargo securement.

    Steering and Suspension Systems

    • Key steering parts include tie rods, steering wheels, hydraulic fluid reservoirs, and power steering cylinders.
    • Suspension defects to look for are cracked spring hangers and missing leaves in leaf springs; severe defects lead to “out of service” status.

    Emergency Equipment and Brakes

    • Required emergency equipment includes fire extinguishers, spare electrical fuses, and warning devices like reflective triangles or flares.
    • Minimum tread depth for front tires is 4/32 inches; for other tires, it's 2/32 inches.

    Backing and Maneuvering

    • Back toward the driver's side for better visibility; avoid right-side backing due to limited sightlines.
    • Use a helper for backing to mitigate blind spots and establish hand signals for communicating movements.

    Driving Techniques and Situational Awareness

    • Always look 12 to 15 seconds ahead while driving; remain aware of vehicle traffic and brake lights.
    • Total stopping distance consists of perception, reaction, and braking distances; speeds increase stopping distance quadratically (four times when speed doubles).

    Handling Hazards and Emergencies

    • Recognize hazards as any possible danger on the road; prepare emergency plans when encountered.
    • In emergencies, sometimes steering away from obstacles can be safer than stopping.

    Drowsiness and Distraction Prevention

    • Combat drowsiness by getting sufficient sleep (8 to 9 hours) before driving.
    • Avoid distractions like mobile devices and pre-adjust all vehicle settings before driving.

    Handling Skids and Braking Systems

    • Understand that vehicles with ABS prevent wheel lock-up; brake safely, applying necessary force without jerking.
    • Brake gently if tires lose traction to maintain control, especially on slippery surfaces.

    Accident Scene Procedures

    • At accident scenes, protect the area, notify authorities, and provide care for injured parties to prevent further incidents.
    • Tire fires often result from under-inflation or dual tires touching; be proactive in tire maintenance.

    Load and Cargo Management

    • Drivers must inspect cargo regularly, ensuring it is balanced, secured, and does not obstruct the driver's visibility or access to emergency equipment.
    • It's essential to stop periodically (every 50 miles or after breaks) to verify cargo safety.

    Fire Extinguisher Usage

    • A B:C fire extinguisher is designed for electrical and liquid fires, while an A:B:C extinguisher works for ordinary combustibles too.
    • Position yourself upwind when using an extinguisher to enhance safety and efficiency.

    Hazardous Materials Awareness

    • Hazardous materials are indicated on vehicles by placards that list the class of the cargo; multiple placards are mandatory for visibility.

    Weight Ratings and Regulations

    • GCWR is the manufacturer-specified weight rating that includes both the vehicle's and trailer's weight, crucial for safe towing.### Weight on Axles
    • Insufficient weight on the steering axle leads to unsafe steering capabilities.
    • Low weight on driving axles causes poor traction and may result in easy spinning of drive wheels.

    Tie-Down Requirements

    • The minimum number of tie-downs for any flatbed load is 2, based on 1 tie-down for every 10 feet.
    • For a 20-foot load, 2 tie-downs are also the minimum required.

    Cargo Coverage Reasons

    • Cargo must be covered to prevent spillage endangering people nearby.
    • Coverage also protects the cargo from adverse weather conditions.

    Sealed Load Checks

    • Inspection of sealed loads is not possible, but checking gross weight and axle weight limits is essential before transport.

    Bus Interior Inspection

    • Key items to inspect in a bus's interior include handholds and railings, floor covering, signaling devices like restroom emergency buzzers, emergency exit handles, and the safety of seats.
    • All seats must be securely fastened to the bus for rider safety.

    Hazardous Materials Transport by Bus

    • Transportable hazardous materials via bus include small-arms ammunition labeled ORM-D, emergency hospital supplies, and drugs.

    Hazardous Materials Prohibited on Bus

    • Prohibited materials for transport include poison gas, explosives, radioactive materials, car batteries, and gasoline.

    Standee Line

    • Buses that allow standing must have a two-inch line, known as the standee line, showing where riders cannot stand.
    • No rider is allowed to stand forward of the rear of the driver's seat.

    Disruptive Passengers

    • Discharging a disruptive passenger must be done with safety in mind for both the rider and others.
    • It is critical not to let such passengers off in an unsafe location.
