Beyond the Myths: A Technical Guide to Defending Speeding Allegations
For many drivers, the flash of a speed camera or the sight of a police officer with a laser gun feels like the end of the story. The assumption is that the evidence is conclusive and the case is closed before it has even begun. However, the area of law that governs the detection and prosecution of speeding offences is incredibly technical and bound by strict procedural rules. A successful defence often lies within these very technicalities.
This guide goes beyond the common myths to explore the real, substantive legal arguments that can form the basis of a robust and successful defence against a speeding allegation. This is the specialised, in-depth knowledge that sets expert solicitors apart from general legal advisors. Challenging the evidence in a speeding case requires a deep understanding of both the law and the technology involved, and at Motoring Defence, our expert speeding offence solicitors have a formidable track record of winning cases by leveraging these very defences.
Technical Defence 1: The Notice of Intended Prosecution (NIP) and Procedural Errors
Before the substance of the speeding allegation is even considered, there is a fundamental procedural hurdle that the police must clear.
The Law: Under Section 1 of the Road Traffic Offenders Act 1988, for most camera-based offences, the police must send a Notice of Intended Prosecution (NIP) to the registered keeper of the vehicle within 14 days of the alleged offence.
The Defence: This 14-day time limit is strict. If the NIP arrives on day 15, it is invalid, and this can provide a complete defence to the charge. A specialist solicitor will meticulously check the dates on the NIP and the postmark to ensure this crucial deadline was met. The notice must also be sent to the correct address on the DVLA database. An administrative error by the police in complying with this statutory requirement can be fatal to their case. The first thing our speeding offence solicitors at Motoring Defence do is verify these procedural details, as a simple error can be enough to have the entire case dismissed.
Technical Defence 2: Challenging the Reliability of the Speed Detection Device
The prosecution bears the burden of proving that the reading from their speed detection device is accurate and reliable. This is not something that can simply be taken for granted.
The Law: Any device used to provide evidence of speeding must be of a type approved by the Home Office, and it must be working correctly.
The Defences: An expert solicitor can challenge the device's reliability on several grounds:
· Calibration: Every device, whether a fixed camera or a mobile laser gun, must have a valid, in-date calibration certificate. Your solicitor can demand that the prosecution produce this document. If it is out of date or does not exist, the evidence from the device is inadmissible.
· Type Approval: The specific model of camera or gun used must be on the Home Office's list of approved devices. Any unapproved device cannot be used to secure a conviction.
· Corroborating Evidence: For some devices, particularly older radar guns, the law requires the police officer's own opinion of your speed to support the machine's reading. A solicitor can challenge whether the officer actually had a clear, unobstructed view for a long enough period to form a valid independent opinion.
We never take the prosecution's technical evidence at face value. The speeding offence solicitors at Motoring Defence are experts at scrutinising the evidence, from calibration records to operational police logs, to find the critical flaws that can win a case.
Technical Defence 3: Issues with Signage, Location, and Identification
The context and location of the alleged offence are just as important as the reading itself.
The Law: For a speed limit to be enforceable, it must be clearly and lawfully signposted, informing drivers of the maximum permitted speed.
The Defence: If the speed limit signs leading up to the location of the alleged offence are missing, incorrect, obscured by trees, or defaced, this can form the basis of a strong defence. The argument is that the driver could not have known what the applicable speed limit was. A solicitor can use photographic evidence, videos of the road layout, and even site visits to prove that the signage was inadequate. Furthermore, in cases relying on a camera photograph, if the quality is too poor to clearly identify the driver behind the wheel, this can also form the basis of a challenge. The team at Motoring Defence investigates every aspect of the case, including the location itself, when building a defence strategy.
These are not "loopholes"; they are legitimate legal and procedural safeguards designed to ensure that no one is wrongly convicted.
