Quick answer
Every legal claim in the United Kingdom has an outer time limit beyond which it cannot be brought. For UK road traffic accidents, the relevant statute is the Limitation Act 1980 (Scotland has its own equivalent, the Prescription and Limitation (Scotland) Act 1973, with similar but not identical periods). The two key deadlines are three years for personal injury and six years for property damage. Missing either deadline means the claim is statute-barred and the court will refuse to hear it. This post explains the deadlines, the narrow exceptions that extend them, and why the deadline should be treated as the outer wall, not the working timetable.

Three years for personal injury - section 11 Limitation Act 1980
Section 11 of the Limitation Act 1980 sets a three-year period for actions in respect of personal injuries. The period runs from the date the cause of action accrued (normally the date of the accident) or from the date the claimant first knew of the injury, the identity of the defendant and the connection between them - whichever is later.
For a typical road traffic injury where the claimant was injured in a collision and knows immediately who hit them, the three years runs from the date of the collision. A claim must be issued in court (not just notified to the insurer or the OIC portal) within three years. After that, section 11 bars the claim absolutely, subject only to the section 33 court discretion to disapply.

Six years for property damage - section 2 Limitation Act 1980
Section 2 of the Limitation Act 1980 sets a six-year period for actions in tort, which includes property damage claims arising from negligent driving. The period runs from the date the cause of action accrued (normally the date the damage was caused, which is the date of the collision in a UK road traffic case).
Six years is generous compared to many jurisdictions but it is still a strict outer wall. A property damage claim issued in proceedings six years and a day after the collision is statute-barred. There is no equivalent of the section 33 discretion for property claims; the court has no power to extend.
The 'date of knowledge' exception in injury cases
Section 14 of the Limitation Act 1980 defines the 'date of knowledge' for personal injury claims. For most road traffic injuries the date of knowledge is the date of the accident or shortly after. For latent injuries that only become apparent years later - chronic neck or back injuries that present years after the impact - the date of knowledge can be later, and the three-year clock starts from then.
The test is when the claimant first knew that the injury was significant, attributable to the defendant's conduct, and that the defendant was the relevant person to sue. The court applies an objective and subjective test combined. Latent injury cases are uncommon in road traffic claims because most injuries present soon after the impact, but they do arise occasionally and shift the deadline forward.
Section 33 discretion in injury cases
Where the three-year period has expired, section 33 of the Limitation Act 1980 gives the court discretion to disapply the limitation period for personal injury claims. The court considers the length of and reasons for the delay, the cogency of the evidence, the conduct of the defendant after the cause of action arose, and the extent to which the claimant acted promptly once they knew the cause of action might exist.
Section 33 is discretionary, not automatic. The longer the delay, the harder it is to persuade the court. A claim issued six months out of time with a good reason for the delay (illness, death of a relative, recent discovery of injury) has a fair chance; a claim issued five years out of time with no good reason is unlikely to succeed. Defendants routinely contest section 33 applications.
Children, adults under disability and military
For children, the three- and six-year clocks do not start running until the child turns 18. A child injured at age 8 has until age 21 to bring the personal injury claim. The Limitation Act 1980 section 28 is the controlling provision. Where the child becomes of age, the claim is filed by the now-adult claimant in their own right.
For adults under a 'disability' within the meaning of section 28 (which includes lacking the mental capacity to conduct proceedings), the limitation period does not run while the disability persists. The clock starts when capacity is restored. Service personnel injured on overseas service are subject to slightly different provisions under the Crown Proceedings (Armed Forces) Act 1987 and the Limitation Act 1980 section 11(7).
Why the deadline should not be the working timetable
The three- and six-year deadlines are outer walls, not working targets. Treating them as a working timetable creates problems on two fronts. First, evidence degrades: witnesses move, memories fade, documents are misplaced, vehicles are scrapped, and the underlying file becomes harder to prove on the balance of probabilities. Second, late claims face institutional resistance: insurers settle later claims for less, defendants raise more procedural objections, and courts are less sympathetic to delay.
The realistic working timetable is months, not years. A non-fault property damage claim should be opened within days, settled within 6 to 18 months, and closed long before the six-year wall. A personal injury claim should be opened within days, formally notified through the OIC portal or a Pre-Action Protocol letter within months, and resolved (whether by settlement or proceedings) within the three-year wall with substantial buffer.
Scotland - different but parallel rules
Scotland has the Prescription and Limitation (Scotland) Act 1973. The personal injury limitation period is three years from the date of the injury or knowledge, similar to England and Wales. Property damage falls under the prescription regime: the obligation to make reparation prescribes after five years (not six) from the date the obligation became enforceable.
The court has discretion under section 19A to allow personal injury claims to proceed out of time, similar to section 33 in England and Wales. The Scottish prescriptive periods are absolute and cannot be extended by court discretion. A claimant pursuing a Scottish road traffic claim should be aware of the five-year property deadline.

Northern Ireland - broadly similar to England and Wales
Northern Ireland has the Limitation (Northern Ireland) Order 1989. The personal injury limitation period is three years; the property damage period is six years; the date-of-knowledge and court-discretion provisions are similar to England and Wales. Cross-border collisions involving NI residents are usually pursued in the jurisdiction where the accident happened.
EU jurisdictional rules pre-Brexit governed cross-border road traffic claims; post-Brexit the position has shifted to the Hague Convention regime in many cases. International road traffic claims should be opened with a solicitor experienced in cross-border practice from the outset.
