What should I photograph after a crash?
More than feels necessary. Both vehicles from several angles, the scene before anything is moved if it is safe to do so, the other driver’s plate and insurance card, the road, the signs and the conditions. Claims are reconstructed from evidence, and photographs are the only evidence that does not fade.
Should I call the police for a minor collision?
Where you can, yes. An independent report of what was found at the scene is valuable, particularly if accounts differ later. If officers do not attend, exchange full details and write everything down while it is fresh, because witnesses on a rural road disappear quickly.
Is it bad to say sorry?
At the scene, yes. It is ordinary decency and it is routinely treated as an admission of fault. Check that people are unhurt, exchange information and leave the fault question to the adjusters, who will decide it on the facts.
