Study Notes

Vehicle Inspection and Safety

Importance of vehicle inspection lies in ensuring safety.
During a trip, continually monitor gauges and mirrors, and use senses to check for problems. Remember to "LOOK, LISTEN, AND SMELL."
Essential steering parts include the steering shaft, tie rod, and gear box.
Suspension system defects may involve cracked spring hangers or leaking shock absorbers.
Carry emergency equipment: three red reflective triangles, spare electrical fuses, and a fire extinguisher.

Tire and Brake Requirements

Minimum tread depth for front tires is 4/32 inch; for other tires, it's 2/32 inch.
Regular checks on wheel bearing seals for leaks are crucial.
Test hydraulic brakes for leaks by applying firm pressure after pumping the pedal three times.
Always keep the starter switch key in your pocket during inspections to prevent unauthorized vehicle movement.

Backing and Turning Techniques

Backing toward the driver’s side improves visibility.
Engage the clutch before releasing the brake to prevent rolling back on hills.
Using a helper is essential when backing due to blind spots.
The most crucial hand signal for communication with a helper is "STOP."

Driving and Hazard Awareness

Downshift before starting down hills or entering curves for better control.
Use engine and road speed to determine when to shift gears.
Maintain awareness by looking 12-15 seconds ahead; observe for road conditions, traffic signals, and potential hazards.
Communicate intentions on the road through signaling.

Traffic Safety and Following Distance

Following distance should be four seconds for a 30-foot vehicle at 55 mph.
Stopping distance increases four times if speed is doubled.
Wet or empty truck conditions increase stopping distances; hydroplaning occurs when tires lose contact with the road.
Black ice is hazardous as it appears wet and unclear.

Stress and Distraction Management

Avoid distractions by assessing in-vehicle factors and making preventative plans.
Recognize characteristics of distracted drivers; they may drift or travel inconsistently.
Maintain personal calmness through listening to music and managing expectations.

Emergency Response and Awareness

Stay cool, avoid confrontations with aggressive drivers, and report risky behavior to authorities.
Emergency plans can mitigate dangers when encountering hazards.
Proper responses at accident scenes involve protecting the area and providing assistance only if safe to do so.

Equipment and Fire Safety

Use extinguishers from a safe distance, staying upwind to avoid flames.
A B:C extinguisher is not effective on regular combustibles or metals.
Key causes of vehicle fires include spilled fuel and under-inflated tires.

Cargo Management and Transportation Regulations

Drivers are responsible for cargo inspection, securement, and weight balance, stopping to check within the first 50 miles and after any breaks.
Gross Combination Weight Rating (GCWR) is the maximum weight allowed, while Gross Combination Weight (GCW) refers to the current weight.
Minimum tie-downs for flatbed loads require at least two, with additional ties based on cargo length.

Bus-Specific Regulations and Safety

Check interior components of buses, including handholds and emergency exits.
Transporting hazardous materials in buses has strict rules; small arms ammo and hospital supplies may be allowed, while more dangerous items such as explosives and certain poisons are prohibited.
A standee line indicates where standing passengers must remain behind to ensure safety.### Disruptive Passengers and Bus Safety
Discharging disruptive passengers should occur in safe areas to prevent danger; preferable at well-lit stops with other people nearby.

Stopping Distances

Stop between 15 and 50 feet from a railroad crossing.
Stop at least 50 feet before a drawbridge when crossing.

Prohibited Practices

Fueling while passengers are on board is discouraged; never refuel in a closed building with passengers present.
Avoid distractions like conversing with passengers while driving.
Do not tow or push a disabled bus with passengers unless it is unsafe for them to exit; always follow company towing guidelines.

Bus Safety Features

The rear door of a transit bus does not need to be open to engage the parking brake; the interlock system manages brakes when the rear door is open.

Hazardous Materials Classes

There are 9 classes of 4-inch, diamond-shaped hazard labels.
Classifications include:
- Class 1: Explosives (e.g., ammunition, dynamite)
- Class 2: Gases (e.g., propane, oxygen)
- Class 3: Flammable liquids (e.g., acetone, gasoline)
- Class 4: Flammable solids (e.g., matches, fuses)
- Class 5: Oxidizers (e.g., hydrogen peroxide)
- Class 6: Poisons (e.g., pesticides, arsenic)
- Class 7: Radioactive materials (e.g., Uranium, Plutonium)
- Class 8: Corrosive materials (e.g., battery acid, hydrochloric acid)
- Class 9: Miscellaneous hazardous materials (e.g., Formaldehyde, Asbestos)

Unclassed Hazardous Materials

ORM-D labeled substances, which include some small-arms ammunition and combustibles like charcoal and lighter fluid.

Air Brake System Maintenance

It is essential to drain air tanks regularly to remove water and compressor oil to prevent freezing and brake failure in cold weather.
A supply pressure gauge measures the air pressure in the tanks.

Low Air Pressure Warning

All vehicles with air brakes must have a low air pressure warning signal that activates when pressure drops below 60 psi; this threshold is 80-85 psi for larger buses.
