KY CDL Passenger flashcards
KY 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 six systems
- Engine compartment, cab and controls, lights and reflectors, brakes, suspension and steering, and emergency equipment. Each system must be checked before every trip and defects documented.
- Air brake static leak test
- With the engine off and pressure at governor cut-out, allowable air loss is 3 psi per minute for a single vehicle. A larger loss indicates a leak requiring repair before departure.
- Low-air warning threshold
- The warning buzzer must sound before pressure drops below 60 psi. Spring brakes must apply between 20 and 45 psi. Know these values for the pre-trip brake check.
- Tire tread minimums
- Front steer tires require at least 4/32 inch tread depth; all other tires require at least 2/32 inch. No cuts, bulges, or exposed cord are allowed.
- Bus emergency equipment
- A passenger bus must carry a charged fire extinguisher, first aid kit, body fluid cleanup kit, and reflective triangles. Emergency exits must be marked and operable.
- Driver vehicle inspection report
- A DVIR is prepared each day for passenger-carrying CMVs. The driver signs it, the carrier reviews it, and repairs are certified before the vehicle returns to service.
- Standee line rule
- A solid line across the floor marks the forward limit for standing passengers. No standee may ride ahead of it or beside the driver while the bus is moving.
- Wheelchair securement
- A wheelchair must be secured with a four-point tie-down and the occupant restrained with a lap and shoulder belt. The wheelchair alone is not an approved seat.
- Aisle clearance requirement
- Baggage, limbs, and mobility devices must not block the aisle, emergency exits, or the standee area. The aisle to the rear door stays clear at all times.
- Pre-departure passenger check
- Before moving, confirm all passengers are seated or behind the standee line, doors are closed, and the aisle is clear. Signal and check mirrors before pulling out.
- Safe stop selection
- Load and unload only at designated stops or safe pull-outs. Never stop in a travel lane, on a curve, or on a hill crest where visibility is limited.
- Emergency exit locations
- Exits include the rear door, marked side windows, roof hatches, and emergency release handles. Drivers must know each location and be able to explain operation.
- Evacuation sequence
- Stop safely, set the parking brake, shut off the engine, turn on hazard lights, then direct passengers to the nearest usable exit. Account for everyone afterward.
- Fire extinguisher PASS
- Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side. Fight only a small fire with a clear escape path behind you.
- Passenger fire response
- Evacuate passengers first and move them at least 100 feet away and upwind. Call 911, then attempt extinguisher use only if the fire is small and escape is clear.
- Railroad crossing stop distance
- Stop within 50 feet but not less than 15 feet from the nearest rail. Open a window, look and listen, and proceed only when the track is clear both ways.
- Stalled on railroad tracks
- Evacuate passengers immediately and move them away from the tracks, toward the direction of an oncoming train, so they are not struck by debris.
- Bus stop signal lights
- Flashing amber warns the bus is preparing to stop. Flashing red with the stop arm extended requires traffic in both directions to stop on undivided roads.
- Following distance formula
- Allow at least one second per 10 feet of vehicle length plus one second. A 40-foot bus needs a minimum 5-second gap in ideal conditions.
- Total stopping distance
- Perception distance plus reaction distance plus brake lag distance plus effective braking distance. Air brake lag adds roughly 0.4 to 0.6 second before braking begins.
- Downgrade braking technique
- Select a lower gear before the descent, use engine braking, and apply brakes in short firm applications. Avoid continuous light braking that overheats the brakes.
- Backing a passenger bus
- Back only when necessary and use a spotter whenever possible. If no spotter is available, get out and check behind the vehicle before backing.
- Night visibility distances
- Low beams illuminate about 160 feet; high beams about 350 feet. Reduce speed so you can stop within the distance your headlights show.
- Fog and heavy rain lighting
- Use low beams in fog, rain, or snow because high beams reflect off precipitation. Reduce speed and be ready to pull off at a safe location if visibility drops.
- Hydroplaning speed
- Hydroplaning risk rises above 35 mph in rain. Reduce speed, avoid cruise control, and brake gently to keep traction on wet pavement.
- Kentucky Move Over law
- Drivers must move over one lane or slow down for stopped emergency, tow, and highway maintenance vehicles displaying flashing lights. The rule applies to buses as well.
- Post-crash driver duties
- Stop, secure the vehicle, set the parking brake, turn off the engine, and turn on hazard lights. Check passengers, call 911, and do not leave the scene.
- Engine fire response
- Do not open the engine cover fully; oxygen feeds the fire. Evacuate passengers, call 911, and use the extinguisher through the available opening only if safe.
- Post-crash testing trigger
- A CDL driver must submit to drug and alcohol testing after a fatal crash or a crash requiring immediate medical treatment away from the scene.
- Kentucky passenger endorsement
- A P endorsement is required to drive a vehicle designed to carry 16 or more passengers, including the driver. A school bus endorsement is separate.
- Kentucky CDL implied consent
- A CDL holder who refuses a chemical test faces license suspension and CDL disqualification. Driving a CMV with a BAC of 0.04 or higher is prohibited.
