Speed Cameras in Southampton

Speed cameras in Southampton: what operates

Southampton has police speed enforcement, combined red light and speed-on-green cameras, motorway enforcement on the M27, and council camera enforcement for some moving traffic restrictions. These are separate programmes. A police speeding or red-light offence can lead to points, while a council School Street or bus gate Penalty Charge Notice is civil enforcement and does not add points to a driving licence.

Hampshire and Isle of Wight Constabulary confirmed the Southampton City Red Light Speed on Green initiative in 2025. It replaces older early-2000s camera equipment at selected junctions with modern systems that can check speeding and red-light offences. The police have also made clear that these cameras are not ULEZ, ANPR surveillance, facial recognition or mobile phone detection cameras.

There is no published Southampton-only timetable saying fixed speed cameras operate only at particular hours. Treat police speed and red-light cameras as capable of enforcement whenever they are live and the relevant limit or signal applies. On the motorway and at roadworks, National Highways average speed and variable limit systems are designed for signed limits that can apply day or night.

Where speed cameras in Southampton are concentrated

Confirmed city camera upgrades are concentrated on major radial and crossing routes rather than quiet residential streets. The first three Red Light Speed on Green locations named by Hampshire and Isle of Wight Constabulary are the A3024 Northam Bridge, the A3024 Northam Road near Brinton's Road, and the A335 Thomas Lewis Way near Dukes Road and Horseshoe Bridge. These are busy routes carrying traffic between the city centre, Bitterne, Portswood and the M27 side of the city.

For drivers searching for speed cameras Southampton, it is important not to confuse yellow police enforcement cameras with general traffic monitoring cameras, bus lane cameras, School Street cameras or CCTV at school keep-clear markings. Only the police speed and red-light systems create criminal motoring offences with points. Council cameras enforce restricted access, bus gates or parking-style restrictions by PCN.

Average speed checks may also appear around signed roadworks, especially on strategic roads such as the M27. These use paired cameras over a measured distance and enforce the signed temporary limit, commonly 50 mph in works, until signs show that the limit has ended.

• A3024 Northam Bridge and Northam Road
• A335 Thomas Lewis Way corridor
• M27 variable or roadworks limits
• Selected School Street entrances

School, red light, work zone and average speed cameras

Southampton does not publish a general school-zone speed camera programme. Instead, the council operates permanent School Streets at schools across the city. Most operate 08:00-09:30 and 14:15-15:45, with entry restricted to permitted or authorised vehicles during those times. Some sites are camera enforced, including bus-gate-style School Streets, and non-permitted vehicles can receive a PCN.

School Street cameras are turned off during published school holiday periods, but the council states that INSET days are enforced. These are access restrictions, not speed cameras, so the normal issue is whether a vehicle entered a restricted street without a permit, not whether it exceeded 20 mph.

Red light speed-on-green cameras combine two kinds of enforcement. When the signal is red, the system deals with red-light running. When the signal is not red, it can enforce the speed limit. Work zone average speed cameras, by contrast, calculate the average between camera points and send evidence to the police if the signed limit is exceeded.

Fines, points, notices and contesting a ticket

If a vehicle is caught speeding by a camera, the registered keeper should normally receive a Notice of Intended Prosecution and a Section 172 request within 14 days. The keeper must identify the driver within 28 days. Failing to provide driver details is treated seriously and can lead to six points and a court fine.

After the driver is named, the usual outcomes are a driver awareness course, a conditional fixed penalty, or a court summons. The normal fixed penalty for speeding is £100 and three points. Higher speeds, existing points, non-response or disputed cases may go to court. Twelve points within three years can lead to disqualification, and new drivers can have their licence revoked if they reach six points within the first two years after passing.

To challenge a police notice, follow the instructions on the notice and keep to the deadlines. Do not ignore it while gathering evidence. For a council School Street or moving traffic PCN, the challenge route is the representation process described on the PCN. A camera alert app such as Speed Camera Radar Detector can help with route planning before setting off, but it is not a substitute for signs, signals and the posted limit.

Local speed limits in Southampton

The default built-up road limit in England is 30 mph unless signs show otherwise. Southampton has expanded 20 mph limits across residential and local shopping areas, including Bassett and Flowers Estate, St Denys, Shirley and Freemantle, Old Redbridge, Woolston and Weston, with further areas considered through the council’s phased programme.

The council’s own evaluation says Southampton keeps 30 mph and 40 mph on a network of strategic, heavily trafficked routes into the city. The M27 is normally a 70 mph motorway for cars where no lower variable or roadworks limit is displayed. Always follow the last legal sign you have passed, including 20 mph residential signs, 30 mph built-up sections, 40 mph arterial sections and any temporary motorway limit.

• 20 mph in many residential areas
• 30 mph built-up default where signed or street-lit
• 40 mph on some strategic city routes
• 70 mph motorway limit unless varied
