BRTA Professional Driving Test key terms

The legal priority one road user has over another at a given moment, such as when a pedestrian is in a crosswalk or a vehicle is already circulating in a roundabout. It is yielded, never taken by force.

A downward-pointing triangular sign telling drivers to slow down and let conflicting traffic or pedestrians pass before entering or crossing. Failing to yield when required is a common cause of intersection collisions.

An intersection where all approaches have stop signs and vehicles proceed in the order they arrived. When two arrive at the same time, the one on the right goes first unless one is turning across traffic.

A solid white line painted across a lane marking where a vehicle must halt at a stop sign or signal. The entire vehicle should remain behind it so pedestrians and cross traffic have clear space.

Painted lines or a distinct pavement pattern showing where pedestrians are meant to cross. Drivers must yield to anyone in it, and passing a vehicle stopped at one is dangerous and often illegal.

An overhead signal, such as a red X or green arrow, that tells drivers whether a specific lane is open or closed. Ignoring it can put a vehicle head-on into oncoming traffic or a work zone.

A lane whose direction of travel changes by time of day, usually to favor rush-hour traffic. Drivers must read the overhead signs before entering because the lane may be flowing toward them.

Painted lines, arrows, and symbols on the road surface that guide or restrict movement. Solid lines generally forbid crossing, while broken lines permit it when safe.

A line marking the outer limit of a travel lane, often separating the roadway from a shoulder. Crossing it should be deliberate and brief, such as for a stop or an emergency.

An acceleration lane that lets a vehicle build speed to join faster-moving traffic. The driver should match the flow of the main road and adjust speed to find a safe gap.

The gap in time or space kept behind the vehicle ahead so there is room to stop if it brakes suddenly. A common rule is at least three seconds in good conditions and more when roads are wet or visibility is poor.

The total distance a vehicle travels from the moment a hazard appears until it is fully stopped. It combines the distance covered during reaction time with the distance needed for the brakes to take effect.

Driving too closely behind another vehicle, leaving little room to react. It reduces the ability to see ahead, removes escape space, and is a leading contributor to rear-end collisions.

A driving approach that anticipates mistakes by others and plans an escape route in advance. It favors smooth speed control, early hazard scanning, and avoiding confrontations on the road.

The skill of noticing developing risks, such as a pedestrian stepping toward the curb or a car edging out of a side street, before they become emergencies. It relies on scanning far ahead and checking mirrors regularly.

The area around a vehicle that mirrors do not show, where another road user can be hidden. Drivers should turn their head or use mirror checks before changing lanes to confirm the space is clear.

Looking into the side and rear mirrors at regular intervals to track traffic behind and beside the vehicle. It should be paired with a shoulder check before any lateral movement.

Moving from one travel lane to another after signaling, checking mirrors and blind spots, and confirming enough space. The maneuver should be smooth and completed without forcing others to brake.

A flashing light on the front and rear of a vehicle that announces an intended turn or lane change. It should be activated early enough to warn others, then canceled after the maneuver.

A manual gesture used to show an intended turn or stop when lights fail or are not visible. Standard arm positions indicate left turn, right turn, and stop.

A loss of braking power caused by heat buildup after repeated or prolonged braking, common on long descents. Drivers should use engine braking and lower gears to control speed and let brakes cool.

Using a lower gear so the engine slows the vehicle without relying only on the brakes. It is especially useful on steep downgrades to prevent overheating and brake fade.

Choosing the gear that matches road speed, load, and grade so the engine runs efficiently and safely. On hills, selecting a lower gear early prevents speed from building beyond control.

A structured check of tires, brakes, lights, fluids, mirrors, and load security performed before starting a trip. It catches defects while the vehicle is stationary and prevents breakdowns and collisions.

The height of the rubber between the grooves of a tire, which affects grip and water drainage. Worn tread increases stopping distance and the risk of hydroplaning on wet roads.

When a layer of water lifts the tires off the road surface so they lose contact and grip. The driver should ease off the accelerator, avoid hard braking, and hold the wheel steady until traction returns.

The actions taken to regain control when tires lose grip, typically easing off the accelerator and steering smoothly in the direction the vehicle should go. Hard braking or sharp steering usually makes a skid worse.

The use of straps, chains, or other devices to keep cargo from shifting or falling during travel. It must be checked before departure and again during the trip as conditions change.

How cargo weight is spread across the vehicle's axles and floor. Poor distribution can overload an axle, reduce steering grip, or make the vehicle unstable in turns and on hills.

The maximum load a single axle or axle group is legally allowed to carry. Exceeding it risks tire failure, brake problems, and fines, and it is checked at weigh stations.

A roadside facility where commercial vehicles are weighed and inspected for compliance with weight and safety rules. Drivers may be required to stop when the station is open.

Rules limiting how long a driver may drive and work before taking required rest. They exist to reduce fatigue-related crashes and are tracked through logs or electronic records.

Planning rest breaks, limiting continuous driving, and recognizing early signs of tiredness such as yawning or drifting. Fatigue impairs judgment and reaction time much like alcohol does.

A record of driving time, on-duty time, and rest periods kept by a commercial driver. Accurate entries support compliance with hours-of-service rules and protect the driver during inspections.

Choosing a path that accounts for road restrictions, bridge heights, weight limits, traffic, and rest stops. Good planning reduces delays, avoids illegal turns, and keeps the schedule realistic.

A posted maximum vehicle height allowed under a bridge or overpass. Drivers must know their vehicle's total height, including any load, and choose a route that clears every structure.

Applying the brakes firmly and quickly to avoid a collision, while keeping the vehicle straight and steering around hazards if needed. It should be practiced so the response is automatic under stress.

The steps taken after a collision: stop, secure the scene, check for injuries, call for help, and exchange required information. Leaving the scene without doing so is a serious offense.

A reflective device placed behind a stopped vehicle to alert approaching traffic, especially at night or on a highway. It should be set out only when doing so is safe.

Flashing lights on all four corners that warn others of a stopped or slow-moving vehicle. They are for emergencies and should not be used to excuse illegal parking.

A written account of what happened, including time, location, parties, and damage. It supports insurance claims, legal proceedings, and the employer's safety review.

Behaving courteously, reliably, and lawfully while representing an employer, including keeping appointments and treating passengers with respect. It builds trust and reduces conflict on the job.

Meeting passengers' reasonable needs through clear communication, patience, and a clean, comfortable vehicle. Good service includes explaining delays and handling complaints calmly.

A short explanation to riders about seat belts, exits, and rules such as staying seated while the vehicle moves. It helps prevent injuries and sets clear expectations.

Wearing and requiring the use of restraints, including for passengers, as the law and policy demand. Belts greatly reduce injury severity and keep occupants in place during sudden maneuvers.

The paved or unpaved strip beside the travel lane, used for emergencies and not for passing or parking except where allowed. Stopping there requires hazard lights and care.
