After a crash — what the law requires

What the law requiresWhere it goes wrongWhat you do
Leaving the sceneForbidden where there is death, injury AND damage to another. Three separate grounds; for each: did he know, or should he reasonably have suspected it.Thinking only injury counts. Sub b mentions damage alone: a clipped mirror in a car park already falls under it.Stop and stay — even with only paintwork damage and even if the other party is absent.
When you may leave after allOnly someone who has PROPERLY given the opportunity on the spot to establish their identity and that of the vehicle falls outside sub a and b.Treating a note under the wiper as enough. “Properly giving the opportunity” is more than a slip that can blow away; and sub c (helpless state) always keeps applying.Leave your details in a way that holds up — call, wait or go via the police, not just a note.
Warning triangleRequired as soon as the stationary vehicle forms an obstacle approaching drivers cannot notice in time. At about 30 metres, clearly visible, facing the traffic it endangers.Always placing it, or never. The criterion is visibility, not how bad the breakdown is; on a bend or crest it must go further back than the measured 30 metres suggests.Place the triangle before doing anything else — it protects you while you deal with the rest.
Hazard lights instead of the triangleWith hazard warning lights on, the duty to place the warning triangle falls away.Turning the exception into a recommendation. It is lawful, but in thick fog or behind a bend hazard lights are less visible than a triangle placed 30 metres earlier.Hazard lights on, and in fog or on a bend the triangle as well — the law permits it, the situation decides.
Stopping and showing documentsOn the FIRST demand of an authorised officer the driver must stop and hand over the documents properly for inspection.Thinking you may first ask why. “On the first demand” leaves no room to negotiate; the question about the reason comes after stopping.Stop on the first demand and hand over the documents; asking why comes afterwards.
The other party drove offThe injured party may then turn to the Guarantee Fund — UNLESS it is plausible that they themselves did not do what could reasonably be expected to identify the driver.Driving off and reporting later. The exception is written exactly for that: noting the plate, asking witnesses and reporting are part of “what could reasonably be expected”.Note the plate, speak to witnesses and report it — that is exactly what “reasonably expected” means.
