Night Lane Closure on a Wet Dual Carriageway
It is 23:40 and you are driving a petrol-engined car on a two-lane dual carriageway outside Rawalpindi. Light rain has been falling for an hour, and the road surface is glossy. Your speedometer reads 70 km/h; an earlier rectangular sign showed an 80 km/h limit. Ahead you see a sequence of temporary roadworks signs: first a warning sign with a lane-closure symbol, then a flashing amber arrow board pointing left, then a line of orange cones tapering the right lane into the left lane. A worker in a high-visibility vest stands near the cones holding a red torch, which he is waving horizontally across the lane. The right lane is closed. A solid white line separates the left lane from a narrow hard shoulder. A slow water tanker with no rear lights is ahead in the left lane. A car behind you is flashing its headlights and closing fast. You need to decide your lane position, speed and response to the worker.
1. What do the arrow board, cones and solid white line require you to do, and how should the wet road change your speed and gap?
Read the worked answer
The arrow board and cones are a temporary lane-closure system: they require you to merge into the left lane before the taper, not to straddle the cones or use the hard shoulder. The solid white line reinforces that you should not cross into the closed side; treat the coned area as occupied. In rain at 70 km/h, the 80 km/h sign is a maximum, not a target. Reduce speed smoothly to a level where you can stop within the distance you can see, probably well below 60 km/h, and increase the gap to the unlit tanker to at least four seconds. The tanker's missing lights mean you may see it late, and wet brakes and tyres need longer to respond. Move left early, signal, and avoid braking on the painted arrow markings, which can be slippery.
2. The worker is waving a red torch horizontally while the arrow board points left. What is the safest interpretation, and what should you do?
Read the worked answer
A red torch waved across the lane is a manual stop signal, and a person controlling traffic takes priority over a static or flashing sign. The arrow board tells you where the open lane is, but the worker may be stopping traffic for a loader, a worker on foot, or a hazard you cannot see. Stop before the cones, not inside the taper. Keep your foot on the brake, hazard lights on if traffic is close behind, and wait until the worker clearly beckons you forward. Do not edge around the cones or follow the car ahead blindly; the car ahead may be past the worker before the signal changed.
3. The car behind is tailgating and flashing headlights as you slow. How should you manage that pressure?
Read the worked answer
Do not speed up into the closure or delay braking to satisfy the driver behind. Brake early and gently, using the brake pedal lightly first so the brake lights warn them, and keep a larger gap ahead so you can stop without harsh braking. If the tailgater tries to overtake into the closed right lane, do not follow or move right to block them; hold your lane and leave them room to abort. If they pass and cut in, drop back further. Your priority is a predictable path through the cones, not teaching the other driver a lesson.
