SD CDL - South Dakota Commercial Drivers License Transporting Passengers Safely Questions and Answers — Questions and Answers
Question 1: What is the primary purpose of the 'standee line' on a bus?
- To indicate the aisle width required for wheelchair access.
- To mark the area where passengers are allowed to stand during travel.
- To show the driver where to stop the front of the bus at a designated stop.
- To indicate the forward-most point where passengers may stand to ensure the driver's view is not obstructed. (Correct answer)
Correct answer: To indicate the forward-most point where passengers may stand to ensure the driver's view is not obstructed.
The standee line, a line on the floor behind the driver's seat, marks the area that passengers may not occupy while the bus is in motion. This regulation ensures that the driver has a clear field of vision and is free from distractions or crowding by passengers.
Question 2: You are driving a bus equipped with a brake-door interlock system. What is the main function of this safety feature?
- It sounds an alarm if a passenger tries to open the door while the bus is moving.
- It automatically locks the passenger door when the bus exceeds 15 mph.
- It applies the brakes and prevents the bus from moving when the passenger exit door is open. (Correct answer)
- It locks the service brake in the applied position if the driver leaves their seat.
Correct answer: It applies the brakes and prevents the bus from moving when the passenger exit door is open.
The brake-door interlock system is a safety feature on many transit buses that automatically applies the brakes and holds them whenever the passenger exit is open. This prevents the bus from moving while passengers are boarding or alighting, reducing the risk of accidents.
Question 3: According to federal regulations, which of the following is a prohibited practice when transporting passengers?
- Transporting a passenger's properly secured, personal-use oxygen container.
- Allowing carry-on baggage to be placed on an empty seat.
- Refueling the bus in a closed building with passengers on board. (Correct answer)
- Announcing upcoming stops over a public address system.
Correct answer: Refueling the bus in a closed building with passengers on board.
Federal regulations strictly prohibit refueling a bus inside a closed building while passengers are on board due to the significant risk from flammable fumes and potential ignition sources.
Question 4: When must a bus driver stop at a railroad-highway grade crossing?
- Only when the red lights are flashing and a gate is lowered.
- The driver must stop at all railroad crossings. (Correct answer)
- Only when transporting more than 15 passengers.
- Only when a train is visibly approaching.
Correct answer: The driver must stop at all railroad crossings.
Regardless of whether lights are flashing, gates are down, or a train is visible, regulations require all buses carrying passengers to stop at all railroad-highway grade crossings. The stop must be made between 15 and 50 feet before the nearest rail.
Question 5: Which of the following is the most critical rule regarding carry-on baggage on a bus?
- All carry-on baggage must be small enough to fit on the passenger's lap.
- Baggage must be stowed in a way that does not block any aisles or emergency exits. (Correct answer)
- The driver is only responsible for baggage stored in the overhead compartments.
- Heavy bags should be stored at the very front of the bus for easy access.
Correct answer: Baggage must be stowed in a way that does not block any aisles or emergency exits.
The highest priority for stowing carry-on baggage is to ensure that it does not create a hazard. All aisles, stairwells, and emergency exits must be kept completely clear at all times to allow for safe movement and rapid evacuation in an emergency.
Question 6: You are the driver for a charter bus tour. When is the best time to make announcements regarding safety features, such as the location of emergency exits?
- Only in the event of an actual emergency.
- While passengers are boarding the bus.
- At the first designated rest stop of the trip.
- After all passengers have boarded and before the trip begins. (Correct answer)
Correct answer: After all passengers have boarded and before the trip begins.
Safety briefings, similar to those on an airplane, should be conducted before the bus begins to move. This ensures all passengers are present and can give their attention to critical information about emergency exits, fire extinguishers, and other safety procedures before any potential incident occurs.
