Night-time encounter with an unlit pedestrian and a glare source
You are driving alone at 23:30 on a paved road through a semi-urban area with street lights on every other pole. It has been raining; the surface is wet and reflective. Your headlights are on dipped beam. A car approaching from the opposite direction has its main beams on and does not dip them. You are travelling at 50 km/h. On your side, a pedestrian in dark clothing steps off the kerb about 35 m ahead, walking diagonally across your path. Your wet-road stopping distance at 50 km/h is roughly 35–40 m, and the oncoming glare has reduced your effective vision to little more than the lit patch immediately in front of you.
1. What is your immediate sequence of actions, and why is each step ordered that way?

Order matters - brake first, then manage the glare, then steer only if needed.
- Ease off the accelerator and brake firmly but progressively. The pedestrian is at ~35 m and your wet stopping distance is 35–40 m, so you are already at the limit. Braking early is the only action that reliably reduces impact energy; delaying it to look or flash costs metres you do not have.
- Do not stare at the oncoming lights. Shift your gaze to the right edge of your lane / the kerb line to preserve night vision and pick up the pedestrian's silhouette against the wet road.
- Flash your headlights once and/or use a brief horn warning to alert both the oncoming driver and the pedestrian - but only after braking is underway, since your hands and attention are needed on the stop first.
- Steer only as a last resort. On a wet, reflective surface at 50 km/h, a sharp swerve risks a skid and loss of control; a controlled stop in your lane is safer if the pedestrian keeps moving.
Key point: on a wet road the tyres have less grip, so braking distance grows and steering authority shrinks - the earlier you commit to braking, the more options remain.
2. If the pedestrian freezes in your path at 20 m, what do you do, and what is the main risk of that choice?
Read the worked answer
At 20 m and 50 km/h on a wet road you cannot stop in time - you need 35–40 m. The least-bad option is a controlled brake-and-steer to the side the pedestrian is coming from or leaving (i.e. aim behind their direction of travel if there is room), while keeping braking pressure on.
Main risk: swerving on a wet, reflective surface at speed can break traction, especially if you brake hard and turn at the same time. The tyres have a combined grip budget - asking them to brake and swerve exceeds it and can cause a skid or spin.
Mitigation: brake hard in a straight line first to shed speed, then release some brake pressure as you steer; keep steering inputs smooth; do not overcorrect once past the pedestrian. Accept that a low-speed impact may be unavoidable and prioritise reducing speed over a dramatic swerve into oncoming traffic.
