What speed actually sets off a camera and the 'myth' you shouldn't gamble on
A motoring expert has revealed how speed cameras actually function and the exact speed that triggers them to catch you out.
With nearly 350 people killed on Britain's roads each year, speed enforcement remains a crucial part of road safety measures. Therefore, drivers have been warned that just because they didn't spot a camera flash, it doesn't mean they've escaped punishment. Car valuation specialists at BigWantsYourCar.com are now warning motorists against believing myths or guesswork about speed limits.
Their spokesperson said: "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 technically breaking the law." This comes after UK drivers were warned over 'avoiding' road instead of having to follow new rule.
How speed cameras actually work
"Not all cameras flash anymore," explains the BigWantsYourCar.com expert. "Some operate silently, and some mobile units are manually operated - so relying on a flash as a warning is a risky game".
They added that, in some cases, the cameras are able to capture crystal clear images of both the driver and passenger, reports the Express.
These systems are able to record: the vehicle's speed; it's registration; the location and time of the speeding incident; and the speed limit of the road.
What speed sets off a camera?
Whilst the National Police Chiefs' Council (NPCC) does suggest a "10 per cent plus two" margin to allow for police discretion, this is not a legal requirement and can differ based on the enforcement area or the officer in charge.
It is important to note that there is a distinction to be made between mobile and fixed cameras. Fixed cameras usually have a predetermined trigger speed, but the exact figure is often kept a closely guarded secret. Handheld cameras, however, are controlled manually by officers.
This means that whether you get fined with a penalty or not can depend on how much you're breaking the limit and the circumstances at the time.
"Mobile speed units are particularly unpredictable," says the spokesperson, adding that "they're frequently set up in areas known for accidents, leading officers to adopt a stricter approach".
With speeding penalties varying from fixed fines to points on your driving licence and even court dates, the smartest move is straightforward. "Don't gamble with the grey area," warns the BigWantsYourCar team, adding that "if you're even slightly over the limit, you're putting your licence, insurance, and safety at risk. No journey is worth that".

Spectacular new £460m road now connecting two major UK motorways
The multimillion pound investment is one of the country's most significant road developments in years, designed to eliminate traffic bottlenecks Gloucestershire is set to see a major transformation in its travel infrastructure with the A417 Missing Link project, which promises to be one of the county's most pivotal road upgrades in recent times. The initiative aims to enhance safety, alleviate traffic jams, and bolster connectivity between the Midlands and the South. A new dual carriageway is being constructed to link two crucial motorways, aiming to eradicate notorious traffic snarls and prevent drivers from using local roads as detours. The "Missing Link" itself is a notorious three-mile single-lane section on the A417, stretching from the Brockworth bypass to the Cowley Roundabout in Gloucestershire. In November 2022, the Government greenlit a £460 million investment to transform the current single carriageway into a state-of-the-art dual carriageway. National Highways has highlighted the importance of the A417/A419 route as it provides an alternative link between Gloucester and Swindon, circumventing the M5 and M4 near Bristol. The planned route will partly trace the existing A417 corridor west of the Air Balloon roundabout, while a new segment will forge a fresh path south and east, skirting around the current road, reports the Express. Additionally, the project includes constructing a new Shab Hill junction to facilitate connections between the A417, A436 towards Oxford, and Birdlip, as well as a new junction close to Cowley to take over from the existing Cowley Roundabout. Moreover, the current A417 stretch between the Air Balloon and Cowley roundabouts is set for a revamp: sections will be transformed into exclusive routes for pedestrians, cyclists, and equestrians, while other parts will remain accessible to local residents. Yet, motorists in Gloucester should brace for disruptions as the A417 will be shut between the Air Balloon roundabout and the A429 Burford roundabout across three weekends. The A417 is slated for temporary closure from the Air Balloon Roundabout to the A429 Burford Road junction over three weekend intervals this summer. The planned shutdowns are scheduled from 11pm on Friday 25 July until 6am on Monday 28 July, from 11pm on Friday 1 August to 6am on Monday 4 August, and once more from 11pm on Friday 29 August to 6am on Monday 1 September. These closures form part of the ongoing enhancement works and are likely to impact travel within Gloucestershire during these periods. National Highways Senior Project Manager Celine Acard commented: "We're making good progress on the scheme but to maintain the programme we need to employ the full closures on this section to facilitate essential work on the utilities chambers. "We fully appreciate that road closures can be frustrating, but we're unable to carry out the work while the road is open to traffic. "We've planned the diversions to minimise disruption, we're anticipating an additional 25 minutes to drivers' travel time and in the meantime we thank people for their co-operation and patience, and advise people to plan ahead and allow a little extra time for their journeys."

Drivers told they risk £1,000 charge if they don't 'take photo' on holiday
A road expert has issued a warning to British holidaymakers in order to avoid 'unexpected charges'. Damage excess fees are a big consideration in car hire contracts Motorists have been warned by an automotive specialist to snap pictures when hiring vehicles during their August holidays. A motoring expert has issued alerts for British travellers regarding the pitfalls holidaymakers should be aware of. Darren Miller from explained: "When it comes to car hire, the cheapest option is often not the best. Many firms offer low quotes initially but compensate by raising excess fees and adding hidden costs. It's important to research thoroughly and consider the total cost rather than just the base price. "Booking a car on arrival at airports, stations, or ferry terminals can be a costly mistake. Fatigue and urgency can lead to overlooking contract details, resulting in unexpected charges. Pre-booking and reviewing the contract carefully can save time, money, and stress." It comes after UK drivers were warned over 'avoiding' road instead of having to follow new rule. "Most car hire companies require the driver to pay with a credit card in their name to cover potential liabilities. This often includes 'ring-fencing' a deposit, which restricts the use of those funds for the duration of your trip. "It's a safeguard for the company, ensuring they can cover any damage or dispute costs," he continued. He went on: "Damage excess fees are a big consideration in car hire contracts. These fees can exceed £1,000, and firms may charge for repairs without providing proof. "To protect yourself, document the car's condition with photographs before you drive off, ensuring any existing damage is recorded." " Car hire companies often push their own expensive insurance policies to cover excess fees, costing up to £200," the expert explained. "However, more affordable and comprehensive policies can be found independently for as little as £20 to £40. It's important to ensure the policy covers the specific make and model of the vehicle you're hiring," he added. "Car hire contracts can have confusing petrol policies and mileage limits, leading to additional charges if not followed correctly. Various 'add-on' fees, such as out-of-hours pick-up, late arrival, and extras like roof racks or child seats, can significantly increase the cost. Understanding and clarifying these terms beforehand can prevent unpleasant surprises."

Wheeler Dealers' Mike Brewer says cars are getting 'harder to fix' as one is 'almost impossible' to repair
Mike Brewer, who is best known for hosting Wheeler Dealers, has slammed modern cars and says they are becoming increasingly difficult to repair as he names one vehicle that is 'almost impossible' to fix Wheeler Dealers favourite Mike Brewer has singled out one motor that is "almost impossible to fix" whilst taking aim at today's vehicles. The telly star has built his reputation by snapping up second-hand cars and restoring them for profit. Yet Mike reckons contemporary motors are becoming increasingly tricky to mend. He claims the troubling trend kicked off with the Audi A2, where drivers were unable to lift the bonnet, being limited to just a "service hatch" instead. Mike reckons we're now stuck in a "disposable society" and suggests drivers are more likely to trade in their motor rather than keep it running, reports the Express. He argues people no longer show their cars the "respect" they once did. On the Talkin' Shop podcast, he said: "Back in my day or your dad's day, when you bought your new car, or your nearly new used car, you would wash it every weekend, you would, every three months, change the oil, change the filter, and hoover it out, and clean it. "We sell cars at One Automotive that are six months old, one year old, and they might come back six months later and it's never seen a car wash. Never had an oil filter, never had the screenwashed." However, Mike reckons manufacturers have deliberately made it tougher to service vehicles. He explained: "I think Audi started it with the A2 when they made that car deliberately with no bonnet. "All you could do was put water in it at the front for your screenwash. It was almost impossible to service the car yourself and then other manufacturers followed suit." Mike claims that many modern vehicles have become a "sea of plastic coverings" beneath the bonnet. He continued: "The manufacturers are saying, 'Don't touch it, leave it alone, bring it back to us and we'll charge you' or 'Don't touch it and wait for it to die'." The television specialist maintains that motors can "go on forever" if they are "looked after right". He referenced lorries which routinely clock up higher mileage as proof of longevity. Mike revealed that vintage automobiles can frequently outlast their modern counterparts when restored with contemporary components. He elaborated: "Today we have different gasket compounds, we have different water compounds, we have different rubber and viscosity in rubber, so the chances are, if you're restoring a car today, the chances are it will run much better and much longer and last forever than it would have done when it came out of the factory." The automotive authority launched his broadcasting journey on Channel 4's Driven - created to compete with BBC Top Gear - before transferring to the Discovery Channel with Wheeler Dealers. He presented 18 series of the programme. Mike has also presented programmes including Wrecks to Riches and Auto Trader. He currently presents the British Rally Championship on Sky Sports.
