Priority rules, intersections, and roundabouts
What this domain tests
This domain tests who goes first at junctions and roundabouts, using Luxembourg's default rules and the signs that override them.
Default rule
In Luxembourg, an unmarked intersection is governed by priorité à droite: you must give way to vehicles approaching from your right. Signs and markings can override this.
Intersections and roundabouts
- At a STOP sign, stop completely at the line, then give way to both directions.
- At a yield sign, slow down and give way; a stop is required only if traffic demands it.
- At a roundabout, give way to traffic already circulating on the ring; signal right before your exit.
- Trams have priority; emergency vehicles with blue lights and sirens have priority when it is safe to yield.
- Do not enter a junction if you cannot clear it; blocking the box is an offence.
Worked example
You arrive at a crossroad with no signs. A car approaches from your right. Reasoning: priorité à droite applies, so you must yield even if you are driving straight on a wider road. If the car were on your left, you would have priority, but you should still be ready to stop.
Traps
Thinking a main road always has priority; entering a roundabout without yielding; signalling left on entry and forgetting the right signal on exit; following a bus or truck through a junction before checking it is clear.
