Austria Theory A key terms

The right of a road user to proceed first at an intersection or narrow section while others must wait. It is granted by signs, signals, or the general right-before-left rule.

The duty to let other road users go first, shown by a yield sign, a stop sign, or a traffic light. Failing to observe it causes most intersection collisions.

The default priority rule at intersections without signs or signals: the vehicle coming from the right has priority. It applies only when no other rule overrides it.

The inverted triangle sign requiring a driver to yield to traffic on the crossing road. The driver need not stop unless vehicles are approaching, but must be ready to do so.

The octagonal stop sign obliging a complete halt at the stop line or, if none, at the point where visibility allows. The driver may proceed only when the road is clear.

A place where two or more roads meet or cross, including T-junctions. Special priority and turning rules apply there, and parking near it is restricted.

A round junction with a central island where traffic circulates in one direction. Unless signs say otherwise, vehicles entering must yield to those already in the circle.

Changing direction at an intersection or junction. The driver must signal in good time and give way to pedestrians and cyclists crossing the road being entered.

The turn indicators used to announce a change of direction or lane. Signalling must be timely and clear, and must be cancelled once the manoeuvre is finished.

Moving from one marked lane to another. The driver must signal, check mirrors and blind spot, and give priority to vehicles already in the target lane.

A brief glance over the shoulder before turning, changing lanes, or pulling out. It covers the blind spot that mirrors cannot show and prevents collisions with cyclists or motorcyclists.

The area around a vehicle that the driver cannot see in the mirrors. It grows with vehicle size, so motorcyclists and cyclists should never linger beside a turning truck.

The distance kept from the vehicle ahead so that a sudden stop can be managed. A common guide is the two-second rule, doubled on wet roads.

The distance travelled while the driver recognises a hazard and starts braking, calculated as speed in metres per second times reaction time. It adds to the braking distance.

The distance a vehicle covers from the moment braking begins until it stops. It rises with the square of speed, so doubling speed roughly quadruples it.

The total stopping distance, being the reaction distance plus the braking distance. It explains why speed limits and safe gaps matter so much in built-up areas.

A legal maximum speed set by sign or by general rule, such as 50 km/h in built-up areas and 100 km/h outside them. Drivers must also slow down when conditions demand it.

The place-name sign marking the start or end of a built-up area. It changes the applicable speed limit and other rules such as parking and noise restrictions.

The maximum permitted blood alcohol concentration for driving, which in Austria is 0.5 grams per litre for most drivers. Novice and professional drivers face a stricter 0.1 limit.

A serious traffic offence recorded in the driving licence register, such as drink-driving or excessive speeding. It triggers mandatory retraining or withdrawal of the licence.

The probationary period for new drivers, lasting three years from first issue. During it, serious offences lead to mandatory training or loss of the licence.

The temporary removal of the right to drive by the authority, usually after a serious offence or a medical or fitness concern. Regranting may require tests or training.

The legal entitlement to drive a particular class of vehicle, granted with the licence. Driving outside the entitled class is an offence and may void insurance cover.

A category of vehicle defined by licence law, such as A for motorcycles, B for cars, or C for lorries. Each class has its own age and test requirements.

The licence class A entitling the holder to ride motorcycles. Progressive access rules limit novice riders to lower power outputs before unrestricted riding is allowed.

Protective gear for motorcyclists including helmet, jacket, gloves, and boots. A helmet is legally required, and full gear greatly reduces injury severity in a fall.

The behaviour of a motorcycle in motion, covering balance, lean angle, and the limited grip available for braking and cornering together. It explains why smooth inputs and early braking matter.

Riding or driving through a bend, requiring speed reduction before the curve, a steady line, and gentle acceleration out of it. Braking hard while leaning risks a slide.

The lean angle of a motorcycle in a curve, needed to balance centrifugal force. It depends on speed and curve radius and is limited by tyre grip and ground clearance.

Painted lines and symbols on the road surface, such as lane dividers, stop lines, and arrows. They guide traffic and can carry binding instructions or restrictions.

The thick painted line where vehicles must stop at a stop sign or traffic light. If it is missing, the stop point is chosen where visibility permits.

A lane marked on the carriageway for a single line of vehicles. Drivers should keep to the rightmost lane unless overtaking or preparing to turn left.

Passing another road user travelling in the same direction. It is only allowed when visibility, space, and signs permit, and a safe lateral gap must be kept.

A sign regulating, warning, or informing road users, grouped into danger, regulatory, and information signs. Their meaning is fixed and must be recognised instantly.

A triangular sign with a red border warning of a hazard ahead, such as a bend, crossing, or slippery road. Drivers should reduce speed and increase attention.

A round sign with a red border prohibiting an action, such as exceeding a speed, overtaking, or entering. Ignoring one is an offence and often a safety risk.

The time a professional driver spends behind the wheel, limited by driving-time rules. Breaks and rest periods are prescribed to prevent fatigue-related accidents.

A state of reduced alertness that slows reactions and can cause microsleep. It is a major accident cause, so regular breaks and stopping when tired are essential.
