ONE in seven speeding offences detected by police in Dorset were cancelled last year, figures reveal.

The RAC Foundation said the hundreds of thousands of fines cancelled each year across England and Wales are evidence that the system for catching and prosecuting speeding motorists is not working.

The charity's analysis of Home Office data shows that Dorset Police recorded 16,640 speeding offences in 2020-21.

Of these, 13,143 (79 per cent) were dealt with by fixed penalty notices and 301 (2 per cent) by speeding awareness courses, while 746 (4 per cent) resulted in someone being taken to court.

A further 2,250 (14 per cent) were dismissed – up from 11% the year before.

Among the reasons why offences could be cancelled are faulty or incorrectly calibrated speed cameras, a lack of resources to bring cases to court, or cloned vehicles carrying a false number plate, according to the RAC Foundation.

Across England and Wales, 17 per cent of all speeding offences were cancelled last year – an increase from 13% in 2019-20.

Steve Gooding, director of the RAC Foundation, said it is important that the systems of detection and prosecution for speeding are robust.

But he added: "The hundreds of thousands of ‘cancelled’ offences each year indicate they are not.

"At the very least it is an administrative burden the police could do without.

“We urge the Home Office to start collecting data from police forces about these cancelled offences so we can understand where the problem lies.”

The 2.4 million speeding cases detected nationally in 2020-21 – a period which included travel restrictions imposed to combat Covid-19 – was down 6% on the previous year.

The number of speeding offences also fell in Dorset, down 30 per cent from 23,825 in 2019-20, making it the lowest number since comparable records began in 2012-13.

A Home Office spokeswoman said: “How the police deal with speeding offences is an operational matter and will be enforced at the discretion of the individual police force.

“Motorists must obey the speed limit, which is there to protect and benefit all road users.

"Forces may take a different approach to speed enforcement depending on local issues, such as targeting dangerous roads to reduce harm or cracking down on high-risk offenders.”
