Iceland Motorcycle Theory Test key terms

The Icelandic statute that sets the binding rules for all road users, including riders: obligations, prohibitions, penalties and the legal basis for signs, speed and priority. Other regulations build on it.

A regulation issued under the traffic act that fills in practical detail, for example on vehicle equipment, licensing, signs and markings. It carries the same legal force as the parent act.

Being in lawful control of a vehicle on a public road. For a motorcyclist it requires a valid licence for the machine's class, the vehicle being roadworthy, and the rider not being impaired.

The licence categories a rider holds and the machine classes each one permits. Riding a motorcycle without the correct category is unlawful, and the insurance position after a crash can become very serious.

Official registration of a vehicle with the authorities, giving it a registration number and a recorded owner. A motorcycle must be registered and have valid plates before it may be used on public roads.

Periodic technical inspection of a vehicle to confirm brakes, lights, tyres, steering and emissions meet requirements. A motorcycle with a lapsed inspection may not lawfully be ridden on public roads.

A fine imposed for a traffic offence, such as speeding or running a red light. Fines can be fixed on the spot or set by court, and serious or repeated offences may also cost the licence.

The police, who enforce traffic law, may stop and check vehicles and riders, require breath or blood samples, and report offences. Riders must obey their signals and produce documents on request.

The duty to stop when required by a stop sign, a red light, a police officer, or after a crash involving injury or damage. Failure to stop is a separate and more serious offence than the original mistake.

The right to proceed first at a junction or narrowing where paths conflict. Priority is set by signs, signals, markings and the general rules, and it is never a right to insist on when another road user has not seen you.

The default priority rule at an unmarked junction: give way to traffic approaching from your right. It applies only where no sign, signal or marking gives a different order.

Any place where roads or paths meet or cross, including T-junctions, roundabouts and private entrances joining a public road. Junction rules on priority, signalling and positioning apply there.

A roundabout where traffic already circulating normally has priority and entering riders give way. Signal to leave, keep to the correct lane, and watch for vehicles crossing your path on exit.

An octagonal red sign requiring a complete stop at the marked line before entering the junction, regardless of whether anything is coming. Riders must be able to put a foot down safely.

Any official sign conveying orders, warnings or information to road users. Shape and colour carry meaning, so a rider must recognise signs quickly at speed and in poor visibility.

Yellow road markings used in Iceland, such as centre lines and edge lines, to separate directions or mark the road edge. Their meaning differs from white markings used for lanes and parking.

A marked longitudinal strip of roadway for a single line of traffic. Motorcycles should normally ride within one lane rather than straddling the line between two.

Merging where two lanes become one, or where a lane ends. Riders must check mirrors and blind spots, signal, and adjust speed so the merge does not force another road user to brake.

Traffic lights controlling movement at junctions, crossings or roadworks. A steady red means stop, green permits movement only if the way is clear, and amber warns of a change.

The speed at which a vehicle is actually travelling, which must stay within the posted limit and also be safe for conditions such as rain, gravel, wind or limited sight distance.

The maximum speeds set by law for roads and areas, shown on signs or implied by the road type. Riding below the limit is still required when conditions demand it.

The distance travelled from the moment braking begins until the vehicle stops. It grows with speed and lengthens sharply on wet, icy or gravel surfaces, and with worn tyres or a loaded bike.

The distance covered while the rider perceives a hazard and moves hands and feet to act. It depends on attention, fatigue, alcohol and visibility rather than on the brakes.

The gap kept to the vehicle ahead so there is time to react and stop. A common guide is at least two seconds in good conditions and more in rain, darkness or on gravel.

The braking system, normally a front and rear brake operated separately on a motorcycle. Both must work effectively, and riders should practise combined use to stop short without locking a wheel.

An anti-lock braking system that rapidly releases and reapplies brake pressure to prevent wheel lock-up. It helps a rider brake hard on slippery surfaces but does not shorten stopping distance on every surface.

The area around a vehicle that the driver cannot see in mirrors, especially beside and behind large trucks and buses. Riders should avoid lingering there and move through quickly.

Awareness of what is happening to the side of the rider, gained from mirrors and shoulder checks. Mirror checks alone leave gaps, so a brief head turn before changing lane is essential.

The way a rider plans, positions and controls the machine: observation, smooth inputs, correct gear and lane position, and anticipation of other road users' likely mistakes.

Continuously reading the road for risks such as gravel, wet patches, animals, parked cars and turning traffic, and adjusting speed and position before the hazard becomes urgent.

A rider's fitness to ride safely at a given moment, affected by alcohol, drugs, medication, illness, fatigue and emotional state. If fitness is in doubt, the ride should not start.

A test of blood alcohol, usually by breath analyser, used by police to check whether a rider is over the legal limit. Refusing a lawful test is itself an offence.

Fatigue from long riding, cold, wind and vibration, which slows reactions and can cause micro-sleeps. It is managed by breaks, hydration and accepting that the ride must end early.

Immediate first aid at a crash scene: securing the area, calling emergency services, checking breathing and bleeding, and keeping the casualty warm and still until help arrives.

The actions taken at an incident: warning other traffic, calling the emergency number, not moving an injured rider unless there is immediate danger, and giving clear information to responders.

A helmet approved to the required standard, correctly fastened and of the right size. It is the single most effective protection against fatal head injury and must not be loose or unfastened.

Protective riding clothing: abrasion-resistant jacket and trousers, gloves, boots and eye protection. It reduces injury severity and also protects against cold and wind fatigue.

A passenger carried on a motorcycle, which requires a proper seat and footrests and a helmet. The rider must adjust tyre pressure, suspension and riding style for the extra weight.

Cargo carried on a motorcycle, which must be securely fixed and must not obstruct lights, steering or the rider's view. Poorly balanced or overloaded loads destabilise the machine.
