A whiplash claim usually requires medical evidence linking your symptoms to the road accident, and you should report the incident to the relevant insurer promptly. In England and Wales, many lower-value road traffic injury claims are handled through the Official Injury Claim service and may be subject to fixed compensation tariffs, depending on the injury and recovery period. You generally have three years to start a personal injury claim, although exceptions can apply and different rules may apply in Scotland or Northern Ireland. Consider speaking to a solicitor regulated by the SRA if your symptoms are significant, liability is disputed, or you are unsure how to proceed.
