Overtaking on a Rural Road
You are driving a 7.5-tonne rigid truck on a single-carriageway rural road with a 50 mph speed limit. The road has a solid white line on your side of the centre line, but there are gaps in the line every 100 metres. You are approaching a slow-moving tractor (15 mph) that is straddling the left edge of the road. The road ahead curves to the right, and you can see about 200 metres ahead. The weather is dry, and visibility is good. There is a car following you closely.

No, you should not overtake. Although the solid white line has gaps, which may permit crossing, the road ahead curves to the right, limiting your view to about 200 metres. At 50 mph, you would need a significant distance to overtake a 15 mph vehicle, and you must ensure you can see far enough ahead to complete the manoeuvre safely. The presence of a following car close behind may also pressure you, but you must not let that influence your judgement. Additionally, your vehicle is a 7.5-tonne truck, which accelerates slowly and has a longer stopping distance. The safe decision is to hold back, maintain a safe following distance, and wait for a clear, straight stretch with adequate visibility and no oncoming traffic before considering an overtake.
2. If you decide to wait, what following distance should you maintain behind the tractor, and why?

You should maintain at least a 2-second gap in good conditions, but because the tractor is slow-moving and you are in a heavy vehicle, a larger gap is advisable-at least 3 seconds. This allows you time to react if the tractor brakes suddenly or turns off, and it gives you a better view of the road ahead. In a 7.5-tonne truck, your stopping distance is longer than a car's, so a greater following distance is necessary. Additionally, the car behind may try to overtake you, so leaving space ahead gives you room to adjust if needed.
