Traffic enforcement cameras are an essential part of road safety in the UK. These devices are designed to detect and deter unlawful driving behaviours such as speeding, red light violations, and entering restricted zones without payment. Whether you're a new driver, a commuter, or a tourist navigating British roads, understanding how traffic enforcement cameras work is crucial to avoiding penalties and staying safe. Here is a map of traffic enforcement cameras in the UK.
In this guide, we’ll explain what traffic enforcement cameras are, how they work, where they are used, and how you can stay compliant with UK driving laws.
What Are Traffic Enforcement Cameras?
Traffic enforcement cameras are surveillance systems installed on roads and intersections across the UK. They automatically record traffic violations, such as:
-
Speeding
-
Running red lights
-
Driving in bus lanes or restricted areas
-
Entering congestion or clean air zones without payment
-
Driving uninsured or untaxed vehicles
These cameras capture photographic or video evidence, including the vehicle’s registration number, location, date, and time of the offence. This information is used by law enforcement and local councils to issue fines or penalties to offending drivers.
Types of Traffic Enforcement Cameras in the UK
1. Speed Cameras
Speed cameras monitor vehicle speeds and issue penalties for drivers exceeding the legal limit. Common types include:
-
Gatso Cameras (rear-facing, radar-based)
-
Truvelo Cameras (front-facing, infrared)
-
Average Speed Cameras (monitor speed over distance)
How Fast Do You Have to Go to Trigger a Speed Camera?
Most speed cameras in the UK are triggered when a vehicle is travelling at 10% over the speed limit plus 2 mph. For example:
-
In a 30 mph zone, the trigger speed is typically 35 mph
-
In a 70 mph zone, it's around 79 mph
However, this is a guideline, not a guaranteed threshold. Enforcement policies vary slightly between police forces, and some cameras have zero tolerance, especially in accident-prone areas.
2. Red Light Cameras
Installed at busy intersections, red light cameras detect vehicles that cross junctions after the traffic lights have turned red. These systems use high-resolution imaging to capture violations in real time.
There are currently an estimated 1,500+ red light cameras in operation across the UK, with the highest concentrations in major cities like London, Manchester, and Birmingham.
3. ANPR Cameras (Automatic Number Plate Recognition)
ANPR cameras scan vehicle number plates and compare them to databases to detect:
-
Stolen vehicles
-
Untaxed or uninsured vehicles
-
Vehicles entering zones like the London Congestion Charge or ULEZ without payment
4. Bus Lane and Box Junction Cameras
These cameras ensure only authorised vehicles use bus lanes and that cars do not block box junctions. They are primarily managed by local councils.
How Do Traffic Cameras Work?
Most traffic enforcement cameras use radar, laser, or infrared sensors to detect violations. When triggered, the camera records the incident, capturing:
-
Vehicle registration
-
Date and time
-
Speed or violation type
-
Location coordinates
If the offence is validated by the relevant authority, the registered vehicle owner receives a Notice of Intended Prosecution (NIP) or Penalty Charge Notice (PCN) through the post.
How to Pay Traffic Fines in the UK
If you receive a traffic fine, you’ll be given payment instructions on the NIP or PCN.
Ways to Pay:
-
Online: Visit the official government or local council website listed on the notice (e.g., GOV.UK Pay a PCN)
-
By phone: Call the number on your notice and pay via debit or credit card
-
By post: Send a cheque or postal order with your reference number
-
In person: Some councils allow payment at designated offices or banks
Discounts and Deadlines:
-
Many fines offer a 50% discount if paid within 14 days
-
Failing to pay on time may result in increased penalties or legal action
Always check the exact instructions on your notice, as procedures vary by council and offence type.
Are Traffic Cameras Always Active?
Yes. Most traffic cameras operate 24/7, regardless of time or weather conditions. Many are clearly signposted, but not all.
Where Are UK Traffic Cameras Located?
Traffic enforcement cameras are widely distributed across the UK. You’ll find them in:
-
City centres: Especially in London, Birmingham, Manchester, and Glasgow
-
Motorways: Such as the M1, M6, and M25
-
School zones and residential areas: To reduce local speeding
-
Congestion and clean air zones
-
Bus lanes and box junctions

How Many Traffic Cameras Are in the UK?
As of recent estimates, there are over 7,000 traffic enforcement cameras in operation, including:
-
3,000+ fixed speed cameras
-
1,500+ red light cameras
-
1,000+ average speed camera systems
-
2,000+ ANPR cameras
-
Hundreds of bus lane, box junction, and congestion charge cameras
This number continues to grow as more areas adopt smart enforcement systems.
How to Avoid Fines from Traffic Enforcement Cameras
-
Stick to posted speed limits
-
Never run red lights
-
Avoid bus lanes during restricted hours
-
Don't enter clean air or congestion zones unless compliant
-
Ensure your vehicle is taxed, insured, and MOT certified
-
Follow box junction rules and signs
