Data Reveals Cornwall Roads with Highest Speeding Offences

New figures have revealed the roads in Cornwall where the highest numbers of speeding offences were recorded last year.

Cornwall Dominates the Regional List

Legal Expert gathered data from Devon and Cornwall Police showing that Cornish roads accounted for six of the 15 worst in the region. Between April 2024 and March 2025, the force issued a staggering 215,047 Notices of Intended Prosecution (NIPs).

Speeding drivers typically face a £100 fixed penalty and a minimum of three penalty points. Reaching 12 points within three years results in disqualification. Devon and Cornwall Police confirmed that 14,240 Fixed Penalty Notices (FPNs) were sent to offenders during the period.

The A30 Roseworthy Dip near Camborne emerged as Cornwall’s worst speeding hotspot, ranking third in the entire region. Police recorded 8,013 speeding offences in just one year, an average of around 22 per day.

Of those, 610 offences led to an FPN, the highest number of fines issued from any single road on the list.

Other Cornish roads also appeared prominently, including:

• Longdowns – 7,267 offences (5th overall)
