THE number of speeding offences recorded by the average speed cameras on the A380 South Devon Link Road have been revealed by a Freedom of Information (FOI) request.

The FOI request covers the full stretch of the 50mph road monitored by the system, beginning just before Penn Inn Roundabout and continuing through to Edginswell.

The data, which is broken down by calendar year since the cameras were installed in 2019, shows the recorded speed of each contravention: offences recorded as more than ten mph over the limit, more than 20 mph over the limit and so on and so forth.

Since 2019, a total of speeding 11,158 offences have been recorded, with 1,699 occurring in 2025.

The vast majority fell either in the one to ten mph bracket or the eleven to 20 mph bracket - some 9,901 offences.

Twenty eight offences were recorded since 2019 as breaking the limit by between 61 and 70 mph, eight of which were in 2025, the FOI request shows.

Provided by National Highways, average speed cameras work by calculating the time taken for a vehicle to travel over a certain distance.

The detection set-up requires cameras in at least two locations. Each vehicle is detected by both an 'entry camera' and an 'exit camera'.

The vehicle registration plate is recorded using Automatic Number Plate Recognition (ANPR) as it passes the entry and exit cameras, then matches the vehicle data recorded.

It calculates the average speed from the known distance between the entry and exit camera locations and the time taken for the vehicle to pass.

If the average speed exceeds the legal speed limit, the system retrieves the ANPR data and recorded images of the passing vehicle together with date and time stamps from both cameras, creating an evidence record which is sent to the police.
