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

Main road sign 2.1

A yellow diamond sign indicating the driver has priority at uncontrolled intersections along the marked route. It is cancelled by sign 2.2 or by entering an intersection where the road is no longer main.

Give way sign 2.4

An inverted triangle requiring the driver to yield to vehicles on the intersecting road. If a STOP sign 2.5 is also present, a full stop is mandatory before proceeding.

No entry sign 3.1

A red circle with a white horizontal bar prohibiting entry for all vehicles from that direction. It differs from a one-way road sign, which permits traffic in the arrow direction.

Built-up area speed limit

The default maximum speed in built-up areas is 60 km/h unless signs indicate otherwise. Towing vehicles and vehicles with trailers are limited to 50 km/h everywhere.

Traffic controller priority

Signals and instructions from a traffic controller override traffic lights, road signs, and markings. Drivers must follow the controller even when a sign or light indicates otherwise.

Solid line 1.1

A continuous white line separating traffic flows in opposite directions. Crossing or straddling it is prohibited, except to avoid an obstacle when no other safe path exists.

Flashing yellow signal

Indicates an uncontrolled intersection or a warning of danger. Drivers must slow down, apply the right-hand priority rule, and yield to vehicles approaching from the right.

Red plus yellow phase

Both lamps illuminated simultaneously warn that the red phase is ending and green will follow. Drivers must remain stopped and may prepare to move but must not proceed.

Yellow zigzag 1.17

Marking at bus stops and taxi stands. Stopping and parking are prohibited there because it would obstruct public transport boarding and alighting.

Additional section arrow

A green arrow in an additional traffic-light section permits movement in that direction only if it does not obstruct others. A red arrow prohibits that direction entirely.

Minimum tyre tread depth

For passenger cars the minimum is 1.6 mm, for trucks over 3.5 t it is 1.0 mm, and for buses 0.8 mm. Tyres with exposed cord are prohibited regardless of depth.

Mandatory vehicle equipment

A first-aid kit, fire extinguisher, warning triangle, and reflective vest must be carried. Trucks require a fire extinguisher of at least 2 kg capacity.

Steering free play limit

The maximum permitted free play measured at the steering wheel rim for a truck is 25 mm. Excessive play indicates a defect that prohibits operation of the vehicle.

Periodic technical inspection

Category C trucks must undergo technical inspection every 12 months. A valid inspection certificate must be carried in the vehicle and presented to GAI on request.

Headlight adjustment rule

Headlights must be aimed so as not to dazzle oncoming drivers. Dipped beam is required at night, in tunnels, and in conditions of poor visibility.

Documents carried by driver

A Category C driver must carry a driving licence, vehicle registration certificate, insurance policy, and waybill or transport documents, and present them to GAI on request.

Leaving accident scene

Leaving the scene of an accident in which someone was injured is a criminal offence. The driver must stop, render aid, and report to the police.

Refusing medical examination

Refusing a medical examination when suspected of intoxication carries the same consequences as driving intoxicated: licence revocation and a fine, with criminal liability for repeat offences.

Seat belt obligation

The driver must wear a seat belt and ensure all passengers do so. Children under 12 must be secured in an appropriate child restraint system.

Two-second rule

Maintain at least two seconds of gap behind the vehicle ahead in good conditions. Double it in rain and quadruple it on ice or in poor visibility.

Stopping distance formula

Stopping distance equals reaction distance plus braking distance. At 60 km/h with a one-second reaction time, reaction distance alone is about 17 metres.

Skid recovery procedure

Release the accelerator, steer gently in the direction of the skid, and avoid sudden braking. Locking the wheels by braking worsens the loss of control.

Severe bleeding control

Apply direct pressure with a clean dressing and elevate the limb. A tourniquet is a last resort and must be marked with the time it was applied.

CPR compression rate

Chest compressions at 100 to 120 per minute, 5 to 6 cm deep, in a ratio of 30 compressions to 2 rescue breaths for an adult casualty.

Warning triangle placement

Place the triangle 15 to 30 metres behind the vehicle in built-up areas and 30 to 100 metres outside them. Switch on hazard lights at the scene.

Load securement duty

The load must be secured so it cannot shift, fall, or obstruct the driver's view. The driver bears responsibility for proper securement before departure.

Rear overhang of load

A load may extend up to 1 metre beyond the rear without marking. Beyond that, a warning flag or light is required, and at night a red light and reflector.

Maximum vehicle dimensions

Height including load must not exceed 4 m, width 2.55 m, and length 12 m for a single vehicle or 20 m for a road train, unless a special permit is held.

Passenger carriage in truck

Passengers may ride only in the cab, up to the number of seats equipped with belts. Carriage in the cargo body is prohibited unless it is specially equipped.

Mirror check interval

Check mirrors every 5 to 8 seconds and scan 12 to 15 seconds ahead. This keeps a full picture of traffic and reveals developing hazards early.

Hazard cue examples

A ball rolling into the road, a driver sitting in a parked car, or a cyclist looking over the shoulder signal a likely hazard. Reduce speed proactively.

Large vehicle blind spots

A truck's blind spots extend along both sides and directly behind the cab. Never linger beside or close behind a heavy vehicle where the driver cannot see you.
