The steps to take if something happens on the road.
Prioritize safety first — move to a safe location if possible and check for injuries — then contact local police to file a report, which is often required for any insurance claim regardless of fault. Contact the rental company's emergency line as soon as possible, since they'll guide you through their specific process.
Document everything with photos, exchange information with any other parties involved, and keep copies of the police report and any paperwork the rental company provides.
