The Rain-Soaked School Run
It is 07:50 on a wet October Tuesday in a Belgian town. You are riding your AM moped to school. The road surface is soaked after 40 minutes of steady rain, and the temperature is 9 °C. You are doing about 40 km/h in a built-up area. Ahead, a line of cars is stopped at a pedestrian crossing, and a group of children with backpacks is walking along the pavement on your right. Just as you approach, one child steps off the kerb between two stopped cars. Your front brake lever is pulled hard. Your moped has a front disc brake and a rear drum brake, no ABS, and the tyres are at the correct pressure but fairly worn.
1. Explain what you should do in the two seconds before reaching the crossing, and why a hard front-brake grab on this wet surface is risky.

Before the crossing you should already have reduced speed and covered the brakes, because the stopped line of cars is a classic occlusion hazard: it hides pedestrians from you and hides you from them. In wet conditions at 9 °C, braking distance grows noticeably and tyre grip is reduced, so the safe approach speed is well below the 40 km/h you were doing. A hard grab of the front brake on a wet, worn tyre risks locking the front wheel: the wheel stops rotating, steering control disappears, and the bike can slide out or pitch you over the bars. Progressive, smooth pressure on both brakes, with more bias to the front but short of lock-up, keeps the front tyre rolling and steering. You should also be ready to stop completely, because a child emerging between cars gives you almost no reaction time.
2. The child appears. Describe your braking and steering response, and what you do if a full stop is impossible.

Apply both brakes firmly but progressively, squeezing the front lever rather than snatching it, and keep the bars straight so the front tyre has maximum grip. Do not swerve toward the oncoming lane unless you have checked it is clear; a blind swerve into traffic is worse than a controlled stop. If you cannot stop in time, aim for the gap the child is not occupying and reduce speed as much as possible before any impact, since kinetic energy rises with the square of speed. Sound the horn only if it does not distract you from braking. After stopping, stay calm, check the child is safe, and only then continue. The core judgement is that speed choice before the hazard, not braking skill during it, determines the outcome.
