What should I do immediately after being involved in a road accident?

Your immediate priority should always be safety and medical attention — for yourself and anyone else involved — before anything else. Once that's addressed, it's important to inform the police promptly so an FIR can be registered, since this becomes important documentary evidence for any later compensation claim or, where relevant, insurance claim.

Try to note down details while they're fresh — the other vehicle's registration number, contact details of the other driver and any witnesses, and if safely possible, photographs of the accident scene, vehicle damage, and any visible injuries.

Get a proper medical examination and keep all treatment records, bills, and prescriptions, even for injuries that initially seem minor, since these become crucial evidence later. If a motor accident claim becomes necessary, having this kind of thorough, contemporaneous documentation makes a significant difference to how smoothly and successfully the claim proceeds, so it's worth consulting a lawyer early rather than waiting.
