Rules of the road and right-of-way
What this domain tests
Rules of the road and right-of-way questions test whether you know who goes first and on which side of the road. Saint Lucia drives on the left, so every junction, overtake and roundabout decision follows from that.
Core rules
- Keep left except when overtaking or turning right.
- Overtake on the right of the vehicle ahead. Never overtake at a pedestrian crossing, on a blind bend, at a hill crest, at a junction or where a solid line forbids it.
- At a roundabout, travel clockwise and give way to traffic already circulating, approaching from your right. Signal left before your exit.
- At an unmarked crossroad, yield to traffic approaching from your right. At a T-junction, traffic on the terminating road yields to traffic on the through road.
- When turning right, wait for a safe gap and give way to oncoming traffic. When turning left, keep close to the left edge and watch for cyclists and pedestrians.
- Give way to emergency vehicles using sirens or flashing lights, but do not break the law or mount the pavement to do so.
Worked example
You reach an unmarked four-way junction at the same time as a car on your right. That car has priority, so you slow, check your mirrors and wait. If the other driver waves you on, proceed only after confirming no other vehicle is coming; a wave does not transfer legal priority.
Traps
Yielding to the left out of habit from right-hand-drive countries; overtaking on the left; entering a roundabout without giving way; and blocking a junction while waiting to turn. Remember that priority is a rule for who should go, not a licence to proceed without looking.
