The idea that you can safely exceed the speed limit by a certain amount is one of the most common myths in motoring
Ever pondered how much you can nudge over the speed limit before getting snapped by a speed camera? With around 350 lives lost annually on UK roads, enforcing speed limits is crucial for keeping our roads safe.
Car experts at BigWantsYourCar.com are cautioning motorists against banking on hearsay or speculation when it comes to speed limits and offer one essential piece of “best advice”.
“We regularly speak with drivers who think there’s a guaranteed buffer – but the truth is, as soon as you exceed the speed limit, you’re breaking the law,” an expert from the company warned.
How speed cameras work
“Not all cameras flash anymore,” the specialist pointed out. “Some operate silently and some mobile units are manually operated – so relying on a flash as a warning is a risky game.”
These high-tech digital machines log:
- The speed of the vehicle
- The time and place of the offence
- The vehicle’s registration details
- The applicable road speed limit
In certain instances they can even snap a crisp photo of the driver and any passengers.
What speed actually sets off a speed camera?
Dispelling a common motoring myth, there’s no legally enshrined “10% plus 2mph” leeway.
The expert spokesperson clarified: “The idea that you’re safe doing 35mph in a 30 zone is one of the biggest myths we hear. Technically, you’re liable for a fine the moment you go even 1mph over the limit.”
Although the National Police Chiefs’ Council (NPCC) suggests a “10% plus 2mph” margin to allow for officer discretion, it’s not set in stone and can differ by area or officer.
Mobile speed cameras vs fixed speed cameras
When it comes to speed enforcement, fixed cameras usually have an undisclosed trigger speed, while mobile cameras offer more human judgement. “Mobile speed units are particularly unpredictable,” noted the expert, explaining that they’re often used in high-risk areas, leading to stricter enforcement.
Best advice? Don’t risk it
The unequivocal advice from the expert is to avoid any temptation to exceed speed limits. They advised: “Don’t gamble with the grey area,” stressing the dangers of even minor speeding infractions, including fines, points, or court dates.
“If you’re even slightly over the limit, you’re putting your licence, insurance and safety at risk. No journey is worth that.”
