Will my speeding fine be cancelled after speed camera fault detected on UK roads?

Thousands of drivers across England are asking the same question after it emerged that a number of speed cameras have been switched off due to a software fault, with fines, court cases and penalty points already being scrapped.

The issue centres on variable speed cameras, most commonly found on smart motorways and major A-roads. These cameras are linked to overhead gantries that display changing speed limits, often lowered during congestion, accidents or bad weather.

A fault was discovered in the software that synchronises the speed limit signs with the cameras themselves. In some cases, the cameras were enforcing a lower speed limit than the one being shown to drivers, meaning motorists may have been wrongly caught speeding.

As a result, affected cameras have been temporarily switched off while the issue is fixed, and police forces are reviewing enforcement data going back several years.

So what does this mean if you have been fined?

Update January 2026: More drivers could have speeding penalties axed

More drivers could see speeding tickets scrapped after officials admitted the net must be cast wider following a fault in variable speed limit cameras.

According to MailOnline, more than 36,000 cases have already been thrown out after a glitch was found in the camera systems, with many linked to the rollout of new equipment around 2021.

But the Department for Transport has now confirmed the issue may go back even further. National Highways has been instructed to review cases from as early as 2019, when upgrade work on the cameras first began, raising the prospect that thousands more penalties could be overturned.

The problem has been traced to a timing fault, where overhead gantry signs changed the speed limit but the cameras did not always update at the same moment — meaning some drivers may have been wrongly caught speeding.

Who could be affected?

You may be in line for a cancellation or refund if you were caught by a variable speed camera rather than a fixed roadside camera, the offence took place on a smart motorway or managed A-road, and the alleged speeding occurred during a temporary or changing speed limit. Reports suggest the issue affects HADECS 3 cameras, which are commonly mounted on motorway gantries rather than yellow roadside poles.

Will my fine be cancelled automatically?

In most cases, yes. If you are affected, you should be contacted directly.

National Highways and police forces are working together to identify cases where drivers were wrongly penalised. If an error is found, fines will be refunded, penalty points will be removed, speed awareness courses will be cancelled or refunded, and court cases may be dropped. Drivers do not usually need to apply, as authorities say they will write to affected motorists once reviews are complete.

What if I have already paid or taken points?

Even if you have already paid the fine, accepted points or attended a speed awareness course, you may still be entitled to redress. Refunds and licence corrections are being processed where mistakes are confirmed.

However, this will not apply to every speeding offence. Fixed cameras, average speed checks and offences where the speed limit was clearly signed and static are not affected.

Where are HADECS 3 cameras installed

The recent software fault has primarily affected HADECS 3 cameras, which are used for variable speed enforcement on managed motorways. These cameras adjust to the changing speed limits displayed on overhead signs, making them the ones most likely impacted by the glitch.

Some known examples of HADECS 3 camera locations include:

• M25 between junctions in Surrey and Kent

• M1 sections in Derbyshire

• M6 in Staffordshire

• M20 in Kent

• M62 in West Yorkshire

• M4/M5 in Somerset

In Scotland, HADECS systems are deployed along the M90 and M9 corridors, covering stretches between Halbeath and Newbridge, with cameras positioned at locations such as Inverkeithing and Queensferry.

Important Notes
HADECS 3 cameras are particularly relevant because they rely on software to sync with variable speed limits. Other types of cameras, such as fixed roadside units or average speed cameras (SPECS / SafeZone), operate independently of variable limits and are not affected by this software issue.

Local police forces may maintain their own camera inventories, meaning the number and type of cameras deployed can vary by region. For instance, data from West Midlands Police shows a mix of HADECS and average speed cameras in their area.

Why This Matters for Drivers
If your speeding notice came from a smart motorway overhead camera, it could have been issued by a HADECS 3 unit affected by the fault. These are being reviewed, and fines or penalty points may be cancelled where errors are confirmed. By contrast, notices from fixed roadside, average speed, or mobile cameras are less likely to be impacted.

Over what period could speeding fines be affected

The software fault affecting HADECS 3 variable speed cameras appears to date back to January 2021. This means fines, penalty points, and speed awareness courses issued from that time on could potentially be affected. Authorities only fully recognised the problem in 2025, after reviewing camera data and court cases, and have since started cancelling fines and notifying motorists.

Drivers caught by smart motorway overhead cameras during this period are most likely to be impacted, while notices from fixed roadside, average speed, or mobile cameras are generally not affected.

What should drivers do now?

If you believe your fine could be linked to a variable speed camera, check the location and date of the offence, look at whether the speed limit was changing at the time, and wait to be contacted by police or enforcement authorities. Drivers are advised not to stop paying fines or ignore court paperwork unless formally told their case is being reviewed.

The bottom line

Not every speeding fine will be cancelled, but for drivers caught by variable speed cameras during temporary limits, there is a real possibility of refunds and points being wiped. If you were caught on a smart motorway and something did not seem right at the time, it may soon be worth checking your post.
