Luxembourg Driving Theory Test flashcards
Luxembourg Driving Theory Test · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Priorité à droite
- The default priority rule in Luxembourg: at an intersection without signs or markings, you must yield to vehicles approaching from your right.
- Priority road sign
- A yellow diamond with a white border grants right of way at all following intersections until an end-of-priority sign or a give-way/stop sign cancels it.
- Roundabout priority
- Vehicles already circulating on the roundabout ring have priority. Entering drivers face a give-way line and must yield before joining the ring.
- Built-up area default limit
- Inside a built-up area, defined by the place-name entry sign, the default speed limit is 50 km/h unless a sign states otherwise.
- Two-second rule
- A safe following gap is the distance covered in two seconds. At 90 km/h that is about 50 metres; at 130 km/h about 72 metres.
- Overtaking a cyclist
- When passing a cyclist, keep at least 1.5 metres of lateral clearance outside built-up areas and at least 1 metre inside built-up areas.
- Motorway speed in rain
- The normal 130 km/h motorway limit drops to 110 km/h in rain or other precipitation. Signs may impose a lower limit at any time.
- Blood alcohol limit
- The legal limit in Luxembourg is 0.5 g/L of blood. Novice and professional drivers are held to a stricter 0.2 g/L limit.
- Alcohol elimination rate
- The body clears roughly 0.10 to 0.15 g/L per hour. Coffee, food, or fresh air do not accelerate this process, so time is the only factor.
- Medication warning pictogram
- A red or amber triangle on a medicine package warns that it may impair driving. Check the leaflet and never combine it with alcohol.
- Reflective vest requirement
- A reflective vest must be carried inside the cabin, not the boot, and worn whenever you exit the vehicle on the road at night or in poor visibility.
- Minimum tyre tread depth
- Tyres must have at least 1.6 mm of tread across the central three-quarters of their width. Winter conditions require suitable M+S or 3PMSF tyres.
- Warning triangle placement
- Place the triangle at least 30 metres behind the vehicle on ordinary roads and about 100 metres on motorways, only when doing so is safe.
- Contrôle technique interval
- Cars undergo a first technical inspection four years after first registration, then every two years. A valid sticker must be displayed.
- Rear fog light rule
- The rear fog light may only be used when visibility drops below 50 metres. Using it in rain or clear conditions dazzles following drivers.
- Aquaplaning response
- Ease off the accelerator, keep the steering steady, and avoid hard braking. Grip returns as the vehicle slows and the tyres regain contact.
- Dutch reach
- Open the car door with the far hand, which turns the torso and makes you check over your shoulder for cyclists before opening.
- Lorry blind spots
- Heavy goods vehicles have large blind areas at the front, both sides, and behind. Never linger beside the cab or pass on the inside of a turning lorry.
- Zebra crossing priority
- Pedestrians who show an intention to cross at a zebra crossing have priority. Approach at a speed that lets you stop safely.
- Emergency number 112
- The European emergency number 112 reaches police, fire, and ambulance services. State the location, the number of casualties, and any hazards.
- CPR compression ratio
- For an adult who is not breathing normally, give 30 chest compressions followed by 2 rescue breaths, and use an AED as soon as one is available.
- Duty to assist
- Failing to help a person in danger is a criminal offence in Luxembourg. Stop, protect the scene, and call the emergency services.
- Constat amiable
- The European accident report is completed and signed by both drivers after a collision. It records facts, not an admission of guilt.
- Compulsory insurance
- Third-party liability insurance is mandatory for every motor vehicle. Driving without valid insurance is a criminal offence in Luxembourg.
- Licence category B
- Category B covers cars up to 3,500 kg with no more than eight passenger seats. Towing a trailer over 750 kg requires B+E or the applicable code.
- Probationary licence period
- New drivers in Luxembourg serve a three-year probationary period, during which stricter rules apply and serious offences can lead to licence withdrawal.
- Eco-driving gear change
- Shift up early, around 2,000 to 2,500 rpm for petrol and 1,500 to 2,000 rpm for diesel, and use the highest suitable gear to cut fuel use.
- Engine braking fuel cut
- While rolling in gear with the accelerator released, fuel injection is cut to near zero. Coasting in neutral instead uses fuel to keep the engine idling.
- Idling engine waste
- Switch off the engine when stopped for more than about 30 seconds, except in moving traffic where restarting would be unsafe. Idling wastes fuel.
- Danger sign distance
- Warning triangles appear about 150 metres ahead of the hazard outside built-up areas and about 50 metres ahead inside them, unless a plate says otherwise.
- Stop versus give-way
- A stop sign requires a complete halt at the line before proceeding. A give-way sign requires yielding to priority traffic without a mandatory stop.
- Solid white line
- A continuous white line must not be crossed or straddled. Broken lines may be crossed to overtake or change lanes when it is safe and permitted.
