AL CDL Passenger flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Pre-trip inspection: emergency exits

Check that all emergency exits (doors, windows, roof hatches) operate properly, are unobstructed, and have legible markings and instructions; verify release mechanisms work.

Parking brake test

Set the parking brake and attempt to move the vehicle; it must hold the vehicle on a grade. Release it before driving.

Tire tread depth minimum

Front tires must have at least 4/32 inch tread depth; all other tires at least 2/32 inch. Also check for damage and proper inflation.

Standee line

A line on the floor marking the area where standing passengers are allowed; they must remain behind it and not block aisles or exits.

Passenger capacity

The maximum number of passengers (including standees) allowed in the vehicle; never exceed the rated capacity.

Wheelchair securement

Wheelchairs must be secured with a four-point tie-down system, and the occupant must use a lap and shoulder belt.

Emergency evacuation distance

After evacuating, move passengers at least 100 feet away from the vehicle and traffic to a safe location.

Fire emergency steps

Stop the vehicle, shut off the engine, evacuate passengers immediately, and call emergency services. Use a fire extinguisher only if safe and trained.

Emergency exit release

If an exit door is inoperable, use the emergency release mechanism or break the glass with the designated tool to escape.

Off-tracking

The tendency of the rear wheels to follow a shorter path than the front wheels during a turn; swing wide to avoid hitting curbs or objects.

Engine braking

Using a lower gear to slow the vehicle on downgrades, reducing reliance on the brakes and preventing overheating.

Air brake low-pressure warning

A warning light and buzzer activate when air pressure drops below a safe level (typically around 60 psi); stop and check the system.

Passenger van rollover risk

Passenger vans have a higher center of gravity and are more prone to rollover; avoid abrupt maneuvers and excessive speed in turns.

Four-second following rule

Under ideal conditions, stay at least four seconds behind the vehicle ahead; increase to six or more seconds in adverse conditions.

Speed for conditions

Never drive faster than is safe for current conditions, even if below the posted speed limit; reduce speed in bad weather, darkness, or heavy traffic.

Lane use for buses

Use the right lane except when passing or preparing for a left turn; keep to the right on multi-lane roads.

Swing wide on turns

When turning, swing wide to account for off-tracking and avoid hitting curbs or pedestrians; signal early and check mirrors.

Railroad crossing stop distance

Stop within 50 feet but not less than 15 feet from the nearest rail before proceeding across the tracks.

Railroad crossing: look and listen

Before crossing, look and listen for trains; open doors or windows if needed to improve visibility and hearing.

Stalled on tracks

If the vehicle stalls on the tracks, evacuate passengers immediately and move them away from the tracks, then call for help.

Night driving visibility

At night, reduce speed, increase following distance, and use high beams when legal and safe; dim for oncoming traffic.

Fog driving

In fog, use low beams, reduce speed, and increase following distance; avoid using high beams because they reflect off the fog.

Mountain driving: engine braking

On long downgrades, use a lower gear and engine braking to control speed and avoid overheating the brakes.

Curve driving technique

Reduce speed before entering a curve, maintain a steady speed through it, and accelerate gently after exiting.

Texting while driving CMV

Texting while driving a commercial motor vehicle is prohibited; using a hand-held mobile phone while driving is also prohibited.

Hours-of-service: driving limit

Passenger-carrying drivers may drive up to 10 hours after 8 consecutive hours off duty; must have 8 hours off between shifts.

Distracted driving

Any activity that diverts attention from driving, such as eating, grooming, or adjusting devices; avoid all distractions while driving.

Post-crash: exchange information

After a crash, exchange names, addresses, license numbers, plate numbers, and insurance details with other involved parties.

Warning devices placement

Place reflectors or triangles to warn traffic; place them within 10 minutes of stopping and at the required distances.

Roadside inspection cooperation

During a roadside inspection, present your CDL, medical certificate, and other required documents; cooperate with the inspector.

Air brake check

Check air pressure buildup and loss rates; know the low-pressure warning and emergency spring brakes if the vehicle is equipped with air brakes.

CDL endorsements

Passenger endorsement (P) is required to drive a vehicle designed to carry 16 or more passengers; other endorsements include hazardous materials (H) and tanker (N).
