Traffic Rules, Right of Way and Intersections
The foundation rules
Brunei drives on the left, so overtaking is normally on the right and roundabouts are negotiated clockwise. At an unmarked junction or crossroads, the general rule is to give way to traffic approaching from your right, but this is a default only: signs, markings and signals always take priority over it. A give way line, a stop line, or a signal-controlled junction overrides the right-hand rule entirely.
Junctions and roundabouts
At a roundabout, give way to traffic already circulating from your right, and signal left to leave. Choose the correct lane early: left lane for the first exit and often for straight ahead, right lane for later exits unless markings say otherwise. At T-junctions the terminating road gives way. When turning right across oncoming traffic, wait for a safe gap rather than edging out and forcing others to brake.
Overtaking and lane discipline
Overtake only when you can see far enough ahead, the road markings permit it, and you can complete the manoeuvre without exceeding the limit. Never overtake at pedestrian crossings, on bends, at hill crests, or where a solid line forbids it. Keep left unless overtaking, and return to the left lane promptly.
Traps in questions
Examiners test the priority order: signals, then signs, then markings, then the default give-way-to-the-right rule. Another trap is the roundabout - learners wrongly give way to the left. A third is assuming a green light gives absolute right of way; you must still yield to pedestrians already crossing and to vehicles blocking the junction.
Worked example
You approach a four-way crossroads with no signs or lights. A car is coming from your right and another from your left, both close. You give way to the car on your right, then proceed when it has cleared, even though the car on your left may move too. If instead the junction has a stop line on your approach, you stop and give way to all traffic before applying the right-hand rule.
