Junction crash: who is at fault

A junction collision is decided by who had the right of way and who failed to stop, give way, or look properly before entering. There is no single rule that always favours one direction. The traffic signs, signals, and each driver’s timing decide it. See who is at fault in a crash for the general approach.

The typical facts in a junction crash

Two vehicles collide where one road meets another, often because one driver entered without stopping at a stop or give-way sign, misjudged a gap, or a signal was mid-change. Motorcyclists are especially at risk here because they are harder to see from a side angle.

How fault is usually assessed

A court looks at which vehicle had the right of way under the signage or signal at that junction. It also asks whether the other vehicle had a genuine, safe opportunity to avoid the crash. A driver who ignores a stop or give-way sign carries a heavy share of the blame, but a driver already in the junction unsafely fast can still share responsibility.

The evidence that decides a junction dispute

• The type of junction control: traffic light, stop sign, give-way sign, or none.
• The point of impact on each vehicle, since a side hit usually shows who entered without clearance.
• Dashcam footage or CCTV from a nearby shop, building, or traffic camera.
• Skid marks, or the absence of them, showing whether either driver reacted at all.
• Witnesses positioned to see both approaches, not just one.

Get the junction’s signage and layout into your police report and photographs before anything changes.^[2] The police report after an accident and dashcam, photo and video evidence cover how to preserve this properly.

Contributory negligence at a junction

A motorcyclist or pillion rider without a helmet can still have their compensation reduced for that, separately from who caused the crash itself.^[1] Contributory negligence explained sets out how courts approach this without fixing a percentage in advance.

What to do at the scene and after

Note which vehicle actually had the sign or signal in its favour, and photograph the junction from a distance that shows both approaches. Motorcyclist support after a crash and a road accident claim cover the next steps once the facts are documented.
