Colorado CDL Passenger flashcards
Colorado CDL Passenger · Build recall with a focused review session.
31 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Pre-trip inspection three parts
- The CDL pre-trip inspection covers the engine compartment, the exterior walk-around, and the in-cab checks. For each item you name the part and state the defect you are looking for.
- Static air brake leak test
- With the engine off and full pressure, watch the gauge for one minute. A loss greater than 3 psi per minute on a single vehicle fails the test and the bus stays out of service.
- Front tire tread minimum
- A front tire on a passenger-carrying commercial vehicle must have at least 4/32 inch of tread depth. Any cord showing or a sidewall bulge also makes it out of service.
- Following distance for buses
- Use at least one second per 10 feet of vehicle length below 40 mph, and add one second above 40 mph. A 40-foot bus therefore needs four seconds minimum, more when loaded or wet.
- Convex mirror distance
- Convex mirrors show a wide view but make objects appear farther away than they really are. Always verify distance with the flat mirror before changing lanes or turning.
- Hydraulic brake pedal test
- With the engine off, pump the brake pedal and hold steady pressure. A pedal that slowly sinks indicates a leak and the vehicle must be placed out of service.
- Standee line rule
- Passengers may not stand forward of the standee line or in the step well while the bus is moving. Standees are allowed only on buses designed and marked for them.
- Aisle and exit clearance
- Baggage, coolers, and strollers must never block the aisle, emergency doors, roof hatch, or window exits. Keep the path to every exit clear at all times.
- Four-point wheelchair tie-down
- Secure the mobility device with four straps at the frame, then use the lap and shoulder belt for the occupant. Check that the device cannot tip or slide before moving.
- Passenger count at stops
- Count passengers when they board and when they leave, and note anyone needing assistance. Never leave a passenger on a parked bus after the trip ends.
- Unloading at a curb
- Stop with the right wheels close to the curb, set the parking brake, and watch passengers cross in front of the bus. Keep hazard lights on during the stop.
- Hazardous items in cabin
- Gasoline cans, fireworks, and other hazardous materials are not allowed in the passenger cabin. Refuse boarding and report the situation to dispatch.
- Pivot-point right turn
- Swing wide enough that the rear wheels clear the curb, then check the right convex mirror through the turn. Watch for cyclists and pedestrians in the right blind spot.
- Railroad crossing procedure
- Stop 15 to 50 feet before the nearest rail, open the window and door to listen, and do not change gears while crossing. Proceed only when the track is clear.
- Curve speed and rollover
- Slow to the advisory speed before entering a curve. Hard braking inside a curve raises rollover risk because a bus has a high center of gravity.
- Skid recovery steps
- Take your foot off the brake, steer in the direction you want the front of the bus to go, and avoid hard braking. Look and steer where you want to travel.
- Night driving visibility rule
- Reduce speed so you can stop within the distance lit by your headlights. Use low beams when following or meeting traffic to avoid blinding other drivers.
- Bus fire evacuation
- Stop, shut off the engine, and evacuate passengers upwind and at least 100 feet away. Call 911 and do not re-board a burning bus.
- Emergency exit drill target
- A bus should be evacuable in about two minutes. Know how to open the rear door, roof hatch, and window exits, and show passengers the exits before a trip.
- Warning device placement
- On a two-lane road, place triangles 10 feet behind and ahead of the vehicle. On a divided highway, place them 10 feet behind and 200 feet to the rear.
- Post-accident testing trigger
- DOT alcohol and drug testing is required after a crash involving a fatality, an injury treated away from the scene, or a vehicle towed from the scene.
- Fire extinguisher PASS
- Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep side to side. Keep an exit path behind you at all times.
- Passenger endorsement threshold
- A P endorsement is required to drive a vehicle designed to carry 16 or more passengers including the driver. A school bus endorsement S is required in addition for school buses.
- Passenger carrier hours limits
- Passenger-carrying CMV drivers generally follow the 11-hour driving limit and 14-hour on-duty limit, with 10 consecutive hours off duty between shifts.
- Conviction reporting deadline
- A CDL holder must report any traffic conviction to the employer within 30 days. Name or address changes must be reported to the state within 30 days.
- DVIR requirement
- Passenger-carrying vehicles require a daily driver vehicle inspection report. The driver reviews it, signs it, and certifies that any listed defects were corrected.
- Annual inspection interval
- Every commercial motor vehicle must pass a periodic inspection at least once every 12 months. The inspection report must be kept available for review.
- Brake pushrod stroke limit
- A brake chamber pushrod stroke beyond the adjustment limit, a missing brake part, or an audible air leak at the chamber places the vehicle out of service.
- Emergency exit out-of-service
- A bus with a blocked or inoperative emergency door, roof hatch, or window exit cannot be dispatched until the exit is repaired and working.
- Steering lash limit
- Steering wheel free play over 10 degrees on a 20-inch wheel, or any looseness in the steering column, is a steering defect that requires removal from service.
- Exhaust and fuel leaks
- An exhaust leak into the passenger compartment or any fuel leak is an immediate out-of-service condition. Repair before carrying passengers.
