The Rain-Slicked Bend and the Overtaking Bus
It is 5:40 p.m. on a two-lane road in Antigua. Rain has been falling for about 20 minutes, so the asphalt is wet but there are no deep puddles. You are driving at the posted 40 mph limit with three passengers. Ahead, the road curves sharply left and the view around the bend is blocked by a wall of vegetation. In your mirror you see a minibus closing quickly; it has been tailgating you for the last kilometre and now begins to pull out toward the centre line as if to overtake. Your own stopping distance on dry tarmac at this speed was roughly 24 metres; the wet surface is likely to extend that considerably. A side road joins from the left just beyond the bend.
1. Should you maintain 40 mph, slow down, or speed up to discourage the bus from overtaking? Explain the reasoning using what the wet road, the blind bend, and the side road each contribute.

Slow down, smoothly and early, and keep well to the left of your lane.
Wet road: braking distances grow on wet asphalt because grip is reduced; the 24 m dry figure could easily become 35–45 m. You need more space and more time, not more speed.
Blind bend: you cannot see oncoming traffic or the road surface beyond the vegetation. If the bus commits to the overtake and a vehicle appears from the opposite direction, the bus will try to cut back in - directly into your path. Leaving a larger gap ahead gives you room to absorb that.
Side road on the left: a vehicle may emerge without seeing you until late, and the bus overtaking near a junction is doubly risky.
Why not speed up? Raising speed on a wet surface into a blind bend shortens your margin exactly where you need it most, and it does not stop the bus - it only shortens the overtake. Why not hold 40? Because conditions have changed since the limit was set. The limit is a maximum for ideal conditions, not a target. Easing off also widens the gap the bus needs and may let it complete the manoeuvre before the bend.
2. The bus begins its overtake just as you approach the bend. What is the safest sequence of actions, and what should you NOT do?
Read the worked answer
Sequence:
- Ease off the accelerator and, if needed, brake gently - do not brake hard while the bus is alongside, as it may lose control or be forced inward.
- Hold your position near the left edge of your lane; do not swerve onto the shoulder or into the vegetation.
- Sound the horn briefly if the bus is drifting toward you.
- Be ready to stop if oncoming traffic appears and the bus tries to squeeze back in.
Do NOT:
- Accelerate to block the overtake - this turns a bad decision by the bus driver into a collision you helped cause.
- Brake sharply mid-overtake - you may be rear-ended or push the bus into the oncoming lane.
- Flash headlights or gesture aggressively - distraction at the worst moment.
The guiding principle: you cannot control the other driver, only your own speed, position and space. Your job is to make the situation survivable, not to teach a lesson.
