NJ CDL Passenger key terms

A required systematic check of a passenger vehicle's critical parts, including brakes, tires, lights, steering, and emergency exits, performed before driving to confirm the vehicle is safe to operate.

A check performed at low speed at the start of a trip to confirm the service brakes stop the vehicle firmly and evenly and that the parking brake holds when applied.

A braking system that uses compressed air to apply the brakes, requiring adequate pressure buildup, no audible leaks, and a working low-pressure warning device before the vehicle is driven.

The linkage component that transfers brake chamber pushrod force to the brake shoe; excessive pushrod travel means brakes are out of adjustment and the vehicle must be placed out of service.

The measured groove depth on a tire; front tires on a passenger vehicle must have at least 4/32 inch of tread and other tires at least 2/32 inch to be legal.

An inspection for cuts, bulges, sidewall separation, exposed cords, and proper inflation, since damaged or underinflated tires can fail suddenly at highway speed with passengers aboard.

Verification that every required exit door, window, roof hatch, and emergency release opens freely from the inside, is properly marked, and is not blocked by seats or luggage.

Confirmation that a charged, properly rated extinguisher is mounted securely, accessible to the driver, and within its inspection date before the vehicle carries passengers.

A written record the driver completes listing any safety defect found during inspection or while driving, so the carrier can repair it before the vehicle is dispatched again.

A prohibition against operating a vehicle or by a driver that fails safety standards, such as defective brakes or an hours-of-service violation, until the condition is corrected.

A marking near the driver's compartment showing where standing passengers may not pass, keeping the aisle and driver's view clear while the bus is moving.

The requirement that aisles, stairwells, and exits stay free of baggage and obstructions so passengers can move safely and evacuate quickly in an emergency.

The practice of ensuring riders are seated or holding handrails before the vehicle moves, and that mobility devices and carry-on items are stowed so they cannot become projectiles.

A four-point strap system plus occupant restraint that anchors a wheelchair securely to the floor so it cannot shift during braking, turning, or a collision.

Stowing luggage so weight stays within axle and gross limits, doors latch fully, and nothing blocks exits, brake lines, or the driver's ability to see and steer.

The maximum total weight a vehicle is designed to carry, including passengers, fuel, and baggage; exceeding it reduces braking and handling performance and is a violation.

The maximum load permitted on a single axle or axle group; overloading one axle, common when baggage is packed at the rear, destabilizes steering and braking.

A tally of riders aboard, kept accurate during boarding and alighting, so the driver knows everyone is accounted for after an evacuation or emergency stop.

Operating a vehicle while attention is diverted by phones, passengers, navigation, or other tasks; commercial drivers are held to strict limits on handheld device use.

The gap kept behind the vehicle ahead; passenger vehicles need at least one second per ten feet of vehicle length at speeds under 40 mph, plus one second.

The total distance traveled from perception to a full stop, combining perception, reaction, and braking distance; it grows sharply with speed and with a loaded bus.

Choosing a safe speed for conditions such as rain, fog, curves, or heavy traffic, and slowing before curves and downgrades rather than braking hard mid-turn with passengers aboard.

Keeping a bus centered in its lane while accounting for its width and rear overhang, and swinging wide enough in turns that the rear wheels clear curbs and poles.

The tendency of a vehicle's rear wheels to follow a path inside the front wheels in a turn, requiring the driver to allow extra room at corners and curbs.

Approaching a right turn by positioning the vehicle so the rear wheels clear the curb, checking mirrors and blind spots, and watching for cyclists or pedestrians on the right.

The safety margin maintained around the vehicle on all sides, giving room to brake, steer, or change lanes when another driver makes an unexpected move.

An intersection where a road meets train tracks; passenger vehicles must stop between 15 and 50 feet from the nearest rail when required and never stop on the tracks.

The mandatory stop before a crossing when carrying passengers, unless the crossing is exempt; the driver opens the door or window to listen and looks both ways before proceeding.

Confirming the lane ahead has enough room to fully clear the tracks before starting across, so the vehicle never stops with any part resting on the rails.

The organized removal of passengers from a vehicle during fire, crash, or other danger, using exits in a planned order and accounting for everyone at a safe gathering point.

The driver's immediate actions on discovering fire: stop safely, shut off the engine, evacuate passengers away from the vehicle, then call for help before attempting any extinguisher use.

Reflective triangles or flares placed behind a disabled vehicle on a highway to warn approaching traffic, set out only when doing so is safe for the driver.

Federal limits on driving and on-duty time for commercial drivers, including maximum driving hours, required rest breaks, and minimum off-duty periods between shifts.

A log, often electronic, showing each day's driving time, on-duty time, and off-duty periods, which the driver must keep current and produce for inspection.

The end-of-shift check for defects, damage, and remaining safety equipment, documented so problems are reported and repaired before the next trip.

Using both flat and convex mirrors plus shoulder glances to monitor areas the mirrors do not cover, especially alongside and directly behind a long passenger vehicle.
