Speeding Fine Appeal UK — Know Your Rights
A speeding fine doesn't have to be the end of the road. The Road Traffic Offenders Act 1988 (RTOA 1988) contains several procedural requirements that — if not met — can make a prosecution unenforceable. Here's what to check before you pay.
The 14-Day NIP Rule
Under RTOA 1988, a Notice of Intended Prosecution (NIP) must be served on the registered keeper within 14 days of the alleged offence. This is a strict statutory requirement. If the NIP arrives after 14 days — check the date on the notice and the postmark — the prosecution cannot proceed unless the delay was caused by the keeper's own failure to notify the DVLA of a change of address.
The 14-day clock starts from the date of the alleged offence, not the date police process the footage. Courts have been strict on this: if the NIP was served on day 15, challenge it immediately.
Section 172 Notices — Who Was Driving?
When a NIP is issued, you will typically receive a s.172 notice asking you to identify the driver. You are legally required to respond. If you were driving, say so. If someone else was driving, name them. If you cannot identify the driver despite taking all reasonable steps, this is a statutory defence — but "I can't remember" alone is generally insufficient.
If the vehicle was stolen, report it to police first and include the crime reference number in your response. The prosecution cannot proceed if you are not the driver and have provided the correct information.
Camera Calibration and Type Approval
Fixed speed cameras and mobile devices must be type-approved and calibrated. You can request disclosure of the calibration certificate and device type approval number. If the device was not operating within its approved parameters, or the calibration certificate had expired, this is a legitimate challenge.
Gatso and Truvelo cameras must have two white lines on the road separated by a set distance. The distance between the lines in the photograph should match the vehicle's travel distance. A discrepancy can indicate a fault.
Temporary Speed Limits and Signage
If you received a speeding fine in a temporary speed limit zone (roadworks, for example), check whether the temporary signs were correctly erected under the Traffic Signs Regulations and General Directions 2016 (TSRGD 2016). Temporary signs must be illuminated at night. If they were missing, damaged, or non-compliant, challenge the notice.
Fixed Penalty vs Court Summons
Most speeding offences result in a Fixed Penalty Notice (FPN) offering 3 points and £100, or a speed awareness course if eligible. If the speed was excessive (typically more than 10% + 9mph over the limit), you may be summoned to court where a magistrate decides the penalty. In court cases, the burden of proof is on the prosecution — beyond reasonable doubt.

What is the 14-day NIP rule for speeding fines?
Under the Road Traffic Offenders Act 1988 (RTOA 1988), a Notice of Intended Prosecution (NIP) must be served on the registered keeper within 14 days of the alleged offence. If it arrives late, the prosecution cannot proceed — unless the delay was caused by the registered keeper failing to update their address with the DVLA.
Can I appeal a speeding fine if I wasn't driving?
Yes. Under s.172 of the Road Traffic Act 1988, you must identify the driver. If you were not driving, you should name the actual driver in your s.172 response. Failure to do so is a separate offence. If the car was stolen, report it to police and provide the crime reference number.
Can a speed camera error invalidate a speeding ticket?
Potentially yes. Fixed speed cameras must be calibrated and type-approved. You can request the calibration records and device approval documentation via the police disclosure process. A device operating outside its approved parameters, or without a valid calibration certificate, may render the evidence inadmissible.
