Flashing Amber at a Box Junction
It is 1:20 a.m. on Corniche Street in Sharjah. You approach a four-way signalised junction and see that the traffic lights are flashing amber on all four approaches. A large yellow criss-cross box marking covers the near side of the junction. In your lane, the white arrow painted on the road points straight ahead only, and a solid white line separates your lane from the lane on your left. A slow truck is approaching from the right at about 40 km/h. Beyond the junction the road is partly blocked by cars queued for a drive-through entrance, and the gap they have left is barely wider than a car.
1. What does the flashing amber signal require you to do at this junction, and how should you approach it?
Read the worked answer
Meaning: outside peak hours, signalised junctions in the UAE revert to flashing amber, which means proceed with caution - it is not a green light. The junction is effectively uncontrolled.
What follows from that:
- You must give way to traffic already in the junction and, in practice, to vehicles approaching from your right (the truck).
- No vehicle has priority asserted by a signal, so priority is decided by yielding, not by who arrives first or who flashes headlights.
- Reduce speed on approach so that you can stop if necessary; cover the brake and scan all four arms, including vehicles whose drivers may assume the side road is clear.
- Watch for drivers treating flashing amber as a green - the risk is highest in the first minutes after signals change.
Wrong instinct: accelerating to 'beat' the truck because your light is not red.
2. The truck has passed. Do you follow the queue of cars into the yellow box marking, and why?
Read the worked answer
No. A yellow criss-cross box means you may enter it only if your exit from the box is clear. Here the far side is blocked by queued cars, so entering would leave you stopped on the marking, blocking cross traffic and the drive-through access.
Reasoning steps:
- Look at the space beyond the box, not at the box itself.
- The gap is described as barely wider than a car - insufficient to guarantee clearing it before traffic stops again.
- Therefore wait before the box, behind the line, and enter only when you can drive straight through and out.
The box is not a waiting area and not a filter lane. Stopping in it is a violation and, at night with limited visibility, a common cause of side-impact collisions.
3. You wanted to turn right at this junction, but your lane arrow points straight ahead only. What is the correct course of action?
Read the worked answer
Continue straight and re-route. A directional arrow painted in a lane is a mandatory instruction, not a suggestion: turning right from a straight-ahead lane is both an offence and a manoeuvre that crosses the path of vehicles in the correct lane.
Reasoning:
- The arrow, the solid white line on your left and the lane you are in all fix your permitted direction.
- Swerving across a solid line at 1 a.m. with poor lighting removes any margin for the truck driver or anyone overtaking on your left.
- The legal and safe recovery is to proceed straight, then use a roundabout, a legal U-turn or the next junction to come back.
Even if you only realise at the stop line, the answer is the same: follow the arrow, then correct your route. Blocking or cutting across to force the turn is the higher-risk choice.
