What to do after a car accident
The order of actions after a collision: safety, recording the scene, exchanging details, notifying your insurer and what comes next. The list adapts to the circumstances.

[ ] Stop and switch on the hazard lights
    Stop without moving the car before the scene is recorded, as far as the rules and safety allow. Hazard lights are the first warning to everyone else.
[ ] Check safety and move people out of danger
    A busy road, smoke or a fuel smell are reasons to get people behind the barrier first and photograph later. Safety outranks paperwork.
[ ] Put out the warning triangle
    Distance and placement are set by local rules. In the dark or in rain, wear a high-visibility vest if you have one.
[ ] Call the emergency services and stay at the scene
    If anyone is hurt, calling is mandatory. Do not move people unnecessarily, stay at the scene and stay on the line with the operator.
[ ] Photograph the wide scene from both directions
    The frames must show the cars' positions, lanes, markings, signs and traffic lights. This is the foundation you cannot recreate later.
[ ] Photograph the damage close up and both number plates
    Each area of damage in its own frame, including small chips and paint transfer. The plates tie the photos to the parties.
[ ] Record skid marks, debris and surroundings
    Skid marks, debris, road surface, weather and visibility all help reconstruct the scene if it is challenged.
[ ] Write down the other driver's details and insurance
    Name, phone, registration, policy details and insurer. Photograph the documents rather than copying by hand: no digits get mistyped.
[ ] Take witnesses' contact details
    Even one person willing to confirm what happened makes everything simpler. Ask immediately: in ten minutes everyone has gone.
[ ] Check how the incident must be documented locally
    In some places a minor incident with no injuries is documented by the drivers themselves; in others the police must attend. Rules change — check the current ones, not the ones you remember.
[ ] Do not sign anything you have not understood
    If the wording is unclear or you disagree, say so and record your disagreement in whatever way the procedure allows. A signature is hard to argue with later.
[ ] Do not agree to settle it informally
    A verbal agreement and money “tomorrow” leave nothing to rely on. Even for minor damage, a record protects both sides.
[ ] Note everything you saw if the other driver left
    Full or partial plate, make, colour, direction, time. Report it when the incident is documented and look for nearby cameras.
[ ] See a doctor if the impact was significant
    Some effects appear later. A medical visit recorded at the time does not have to be proved afterwards.
[ ] Notify your insurer within the required time
    There is a deadline for notification and it is shorter than people think. Call or file immediately, even before you decide about repairs.
[ ] Keep every document and photo in one place
    Photograph every piece of paper as you receive it. One folder on your phone or in the cloud saves you recovering losses a month later.
[ ] Book the inspection and damage assessment
    Inspections have deadlines and appointments take time. Set a task with a date on it, not “sometime this week”.
[ ] Plan the repair as separate tasks
    Choosing a garage, approvals, timescales, a courtesy car — each is a separate task with its own date. In a list they do not get lost.
