Overtaking a Shedding Load in Heavy Rain
You are driving a small hatchback on a two-lane trunk road outside Soma. The sign says 60 km/h, but rain is falling hard and spray reduces visibility. Ahead, a lorry loaded with maize sacks is doing about 40 km/h. One rope across the load is loose and flapping, and a mudflap has broken away. You have followed it for 2 km. Oncoming cars appear suddenly through the spray. A boy on a bicycle rides on the narrow shoulder ahead of you. A single-lane bridge with solid white edge lines is about 100 m ahead. Your wipers are on full speed and your windscreen is beginning to mist. You are due at a meeting in Banjul and are already running late.
1. Identify the hazards in this scene and explain whether you should overtake the lorry now.

The hazards compound each other: heavy rain and spray cut visibility; the lorry's loose rope shows the load may shift or fall; the broken mudflap suggests poor maintenance; the cyclist has little room and may swerve around a pothole; the bridge narrows the road and its solid edge lines leave no safe escape space; and oncoming traffic appears late through the spray. Overtaking now would be unsafe because you cannot see far enough ahead to guarantee a clear gap, and even a short overtake would put you alongside the lorry near the bridge with a cyclist on the left. Being late is not a reason to accept a blind risk. Stay behind, reduce speed, and treat the loose load as a reason to increase your gap rather than close it.
2. What following distance and lane position should you use, and what conditions would make overtaking safe later?

In wet weather, double the normal gap: aim for at least four seconds behind the lorry, and more if spray is heavy. Position yourself slightly to the left of the lane centre to see past the lorry without straddling the centre line, but do not tailgate or sit in the lorry's blind spot. Use dipped headlights, clear the mist with the demister, and watch the cyclist and oncoming traffic. Overtake only after the bridge, when you have a long clear straight, no oncoming vehicle is visible through the spray, the cyclist is well behind you, and you can complete the pass without exceeding the limit or forcing anyone to slow. Signal, check mirrors and blind spot, and if any doubt remains, stay back.
