The Two-Lane Roundabout at Dusk
At 18:40 on a Thursday in Muscat you approach a large three-exit roundabout in a light hatchback. The approach has two marked lanes: the right-hand lane arrow points right and straight ahead, the left-hand lane arrow points left only. Your destination is the second exit, straight across. The sun is low behind you and the tarmac is glare-bright. A pick-up is on your left, half a car length ahead, indicator off. A taxi is close behind you, and its driver has already flashed headlights twice. On the circulating carriageway a white saloon is coming round from your left at about 40 km/h, and a second car is following it closely. Your speed is 45 km/h as you reach the broken give-way line, and you have not checked right again since reading the lane arrow.
1. Which lane should you be in for the second exit, and what does the left-lane arrow tell you?
Read the worked answer
Your exit is the second, straight ahead, so the correct lane is the right-hand lane: its arrow permits right and straight, and it keeps you on the outside of the anticlockwise circulation for the shortest time. The left lane is arrowed left only, so it is reserved for traffic taking the third (final) exit. This matters beyond legality. If you enter from the left lane and then cut across to exit straight ahead, you cross the path of any vehicle legitimately in the right lane and of circulating traffic on your outside, and in a roundabout your lane position is a signal other drivers read. If you were already committed in the left lane at the arrow, the safe correction is to take the third exit and turn back at the next junction, not to swerve across the right lane at the exit mouth.
2. The give-way line is just behind you and the white saloon is about 15 m away on the circle. What do you do?
Read the worked answer
The give-way line means traffic already circulating has priority, and it is coming from your left at 40 km/h, roughly 15 m away, under two seconds. You cannot both enter and be clear before it arrives, so you stop at or before the line. Do not edge out to claim the gap: a circulating driver is not obliged to slow, and if the saloon brakes hard the car behind it may not. If your bonnet is already over the line, hold position and wait; an awkward position is better than a collision. Move only when the gap to the next circulating vehicle, plus the gap behind it, lets you accelerate to circulating speed without making anyone brake. Re-check both directions after the first car passes, because the second is hidden in its shadow.
3. The taxi behind is tailgating and flashing its lights. How should that change your decisions?
Read the worked answer
It does not change the give-way rule, and it cannot transfer priority to you. If the taxi's pressure shortens your gap or pulls you out into the circle, you create a collision that is both physically and legally yours. Practical response: hold a steady, predictable speed, signal your exit direction early and correctly, leave a bigger gap ahead so you can brake gently rather than sharply, and avoid any sudden lane change to escape the taxi. Once you are on your exit, if it is still glued to your bumper, move to the right and let it pass when it is genuinely safe. Provoking it or blocking it is not your job, and escalation at 45 km/h in traffic is a real hazard.
