Pedestrians and bicyclists can be a hazard for commercial drivers. What are some clues you should look out for when pedestrians and bicyclists are nearby?

• Walkers, joggers and bicyclists may be on the road with their back to the traffic, so they cannot see you
• All of these are legitimate clues to look for
• They may be wearing portable stereos with headsets, so they cannot hear you
• On rainy days, pedestrians may not see you because of hats or umbrellas

When should you turn the engine "retarder" off (Commonly known as the "Jake Brake")

• At night or on narrow roads
• When your gross weight exceeds the braking pressure
• Whenever the road is wet, icy, or snow-covered.
• If two or more cylinders indicate overheating

What should you do at the end of the trip, the day, or the tour of duty on each vehicle you operated?

• Do an inventory of the cargo
• Do an after-trip inspection
• Log the time spent at each shipper or consignee

Brake adjustment can affect brake fade. Describe how:

• Brakes that are in adjustment will stop doing their share before those that are out of adjustment. The other brakes can then overheat and fade, and there will not be enough braking available to control the vehicle(s).
• All of these are correct
• Brakes out of adjustment will stop doing their share before those that are in adjustment. The other brakes can then overheat and fade, and there will not be enough braking available to control the vehicle(s).
• Brakes out of adjustment will stop doing their share before those that are in adjustment. The air pressure can build up from the heat, and there will not be enough braking available to control the vehicle(s). Air pressure must be reduced to resume proper braking.

The warning light and buzzer should shut off when the air pressure in both air brake systems rises to a value set by the manufacturer. This value must be:

• Greater than 120 psi
• Greater than 100 psi
• Less than 60 psi
• Greater than 60 psi

What are two ways of knowing when to shift?

• Transmission type and engine type
• Road conditions and oil pressure
• Vehicle weight and length of trailer
• Engine speed and road speed

What can you do as a bus driver to ensure safety in case of an emergency?
