What counts as a road traffic accident?
A road traffic accident is any collision or incident on a public road or in a public place involving a vehicle. People usually think of a car crash, but the same legal framework — and the same valuation method — covers a much wider range of road users. The injuries and the insurance issues differ by vehicle type, which is why this site has a dedicated calculator for each one:
- Car accidents — by far the most common RTA, dominated by whiplash and soft-tissue injuries, plus claims by passengers who were not driving.
- Motorcycle and motorbike accidents — riders have little protection, so injuries (and therefore payouts) are typically more severe.
- Truck and HGV accidents — collisions with heavy goods vehicles cause disproportionate injuries and larger claims.
- Bus, taxi, Uber and rideshare accidents — passenger claims against a commercial carrier or its insurer.
- Vulnerable road users — cyclists, e-scooter riders and pedestrians hit by a vehicle.
- Train accidents — covered here too, valued on the same injury-bracket principles.
Whichever applies to you, the wider category is the road traffic accident calculator, which estimates any RTA claim from the injury and your losses.
The road traffic accident claim process, step by step
Almost every RTA claim follows the same path, whether it is a minor whiplash case or a life-changing injury. Understanding the sequence helps you avoid the two most common mistakes: settling before your injury has stabilised, and missing the legal deadline.
- Get medical attention and a diagnosis. Your medical records are the backbone of the claim. Even if you feel "shaken but fine", whiplash and soft-tissue symptoms often appear a day or two later.
- Preserve the evidence. Photograph the scene and vehicle damage, save dashcam footage, take the other driver's details and insurer, collect witness contacts, and get a police or incident reference number.
- Notify the insurers. Report to your own insurer promptly (most policies require it) and identify the at-fault driver's motor insurer, who will ultimately pay.
- Obtain an independent medical report. A medico-legal examination sets out your injuries, treatment and — crucially — your prognosis, which drives the general-damages value.
- Value general and special damages. General damages come from the Judicial College Guidelines (UK) or typical settlement ranges (US); special damages add your lost earnings, treatment, care and vehicle costs. See general vs special damages.
- Negotiate the settlement. Insurers usually open low. Read should I accept the first offer? before responding — early offers are frequently below the true bracket value.
- Settle or, rarely, go to court. The large majority of RTA claims settle out of court; only a small minority proceed to a hearing. See settlement vs going to court.
How long does a road traffic accident claim take?
There is no single answer, because the timeline tracks the injury, not the paperwork. The golden rule is that a claim should not settle until your prognosis is clear — settling early can leave you under-compensated if symptoms persist. As a realistic guide:
| Type of RTA claim | Typical timeline |
|---|---|
| UK whiplash via Official Injury Claim portal | 2–8 months |
| Soft-tissue injury, liability admitted | 4–9 months |
| Fracture or moderate injury, full recovery | 9–18 months |
| Serious injury or disputed liability | 18 months – 3 years |
| Catastrophic injury with lifelong losses | 3+ years |
For a fuller breakdown see how long a personal injury claim takes. Whatever the timeline, you must start within the legal time limit — generally three years from the accident in England & Wales, and commonly two to three years per state in the US.
Who pays, and what if the driver was uninsured?
In nearly all RTA claims the compensation is paid by the at-fault driver's motor insurer, not the driver personally — which is exactly why motor insurance is compulsory. If you were partly to blame, your award can be reduced for contributory negligence (for example a percentage cut for not wearing a seatbelt). If the other driver was uninsured or untraced, UK claims can be made through the Motor Insurers' Bureau; many US states have uninsured/underinsured motorist (UM/UIM) cover that does the same job.

How long does a road traffic accident claim take?
A straightforward claim with a recovered injury often settles in about 4–9 months. Small UK whiplash claims through the Official Injury Claim portal can be quicker. More serious claims involving ongoing treatment, disputed liability or future losses commonly take 18 months to 3 years, because the claim should not settle until your long-term prognosis is clear.
Who pays compensation after a road traffic accident?
The at-fault driver's motor insurer normally pays, not the driver personally. If the other driver was uninsured or untraced, UK claims can be made through the Motor Insurers' Bureau, and many US states have uninsured/underinsured motorist cover that performs the same role.
What are the steps in a road traffic accident claim?
Get medical attention and a diagnosis, gather evidence (photos, dashcam, witnesses and a police reference), notify insurers, obtain an independent medical report, value general and special damages, then negotiate a settlement. Most claims settle out of court.
Is a car accident the same as a road traffic accident?
A car accident is one kind of road traffic accident. The wider RTA category also covers motorcycles, vans, trucks, buses, taxis, rideshare vehicles, cyclists, e-scooter riders and pedestrians. The valuation method is the same across all of them — injury value plus financial losses.
