Related: Aisle clearance, Passenger securement
Aisle clearance

The required clear width and height along the bus aisle, kept free of baggage, coolers, and loose objects so passengers can move to exits without tripping or being trapped during an emergency.

Related: Standee line, Emergency evacuation
Passenger securement

Related: Wheelchair tiedown, Aisle clearance
Wheelchair tiedown

The strap or locking system that anchors a wheelchair to the bus floor, used together with an occupant restraint belt so the rider stays in place during braking, turning, or a collision.

Related: Passenger securement, Lift operation

Deploying and controlling the wheelchair lift or ramp safely, including setting the parking brake, checking the area around the lift, and confirming the rider is positioned and secured before raising or lowering.

Related: Wheelchair tiedown, Kneeling bus

A bus feature that lowers the front or door-side suspension to reduce the step height, making boarding easier for older riders, people with disabilities, and anyone carrying packages.

Related: Lift operation, Boarding

Related: Boarding, Pull-out gap
Pull-out gap

The safe space a driver creates before re-entering traffic from a bus stop, using mirrors and turn signals to confirm no vehicle is approaching and that merging will not force others to brake.

Related: Alighting, Mirror check
Mirror check

Scanning the left, right, and interior mirrors in a set pattern to see vehicles alongside, passengers moving in the aisle, and the door area, especially before changing lanes or leaving a stop.

Related: Pull-out gap, Blind spot
Blind spot

An area around the bus that the driver cannot see directly or through the mirrors, such as directly behind the rear or beside the front door, where a car or pedestrian may be hidden.

Related: Mirror check, Pedestrian awareness
Passenger management

The driver's ongoing job of monitoring riders, enforcing safety rules, and addressing disruptive behavior calmly and early so the bus stays orderly and the driver can keep attention on the road.

Related: Disruptive passenger, Distracted driving

Related: Emergency evacuation, Hazard lights
Hazard lights

Flashing four-way lights used to warn other drivers when the bus is stopped, disabled, or moving slowly, making the vehicle more visible and reducing the chance of a rear-end collision.

Related: Emergency reflector
Distracted driving

Operating the bus while attention is taken by phones, passengers, paperwork, or other non-driving activity; it is a leading cause of crashes and is restricted by law and company policy.

Related: Passenger management, Following distance
Following distance

Related: Stopping distance, Distracted driving
Stopping distance

The total distance needed to bring the bus to a halt, combining the distance traveled while the driver reacts and the distance covered while the brakes slow the vehicle.

Related: Following distance, Speed management
Speed management

Choosing and holding a safe speed for the road, weather, and load, including slowing before curves, ramps, and stops, because a loaded bus needs more room and time to slow down.

Related: Stopping distance, Off-tracking
Off-tracking

The tendency of a bus's rear wheels to follow a path inside the front wheels during a turn, which can cause the rear to strike a curb, pole, or pedestrian if the driver turns too tightly.

Related: Speed management, Right turn squeeze
