What happens if the other driver lies about how the crash happened?

Practically, a dishonest account usually helps the honest party once evidence lands, because inconsistencies compound. What hurts a claim is an injured person whose own account drifts — a guessed speed, an estimated distance, or a detail added weeks later that the photographs contradict.

What to do: write your own account the same day while it is exact, and mark what you do not know rather than filling gaps. Preserve the vehicles photographically before repair, because impact geometry is often decisive. Chase video immediately — business, residential, transit and dashboard footage is commonly overwritten within days or weeks. Get witnesses' names and phone numbers, since an independent witness usually resolves a two-story dispute. Read the crash report for factual errors and ask the investigating agency about a supplemental report where something is wrong. If the insurers deadlock and the claim is denied on liability, the dispute can still be resolved in litigation, where sworn testimony, subpoenaed records and phone data replace the phone-call version of events. In serious cases, a reconstruction expert can establish speeds and positions from the physical evidence alone.
