Mercedes stopped doing 129mph on the M5

560 drivers were stopped, of these 132 were drivers of light commercial vehicles which have a lower speed limit.

Operation Logjam was organised by the newly formed Devon and Cornwall Police No Excuse team.

MPC Ralph Delbridge of the No Excuse Team, who led the Operation, said: “We were able to offer discretionary words of advice to several commercial drivers. Additionally, Highways England staff conducted surveys with drivers as part of their ‘Driving for Better Business’ approach and will follow these up with company and fleet managers to further educate, not only the drivers but also the employers.

“This helps to ensure that employers are aware of the speed restrictions their drivers have to work within and to ensure not only that realistic scheduling is compiled, so that they do not have to speed between jobs or deliveries, but also that they take into account the Health and Safety of their driving staff. This further protects all road users from the risk of harm or serious injury."

Here's some of the "highlights" of their day: 

• One car driver was recorded at 129mph on the M5

• One was reported for inconsiderate driving, ironically having headlight flashed an unmarked ‘No Excuse’ vehicle to get out of his out of his way as he sped along the A38.

• A driver was caught using a mobile phone whilst driving and a delivery driver was found to have a tyre with only 1.2mm tread remaining with a further light commercial tyre worn with structural cord exposed.

MPC Delbridge continued: “I’m pleased to report that all the breath tests conducted on drivers stopped for offences were negative.

“Working with our partner agencies is a superb way of ensuring that the education does not cease at the roadside and is taken forward as a joint approach to making the roads safe for all to use.

With Christmas approaching we would like to see all our road users enjoying it with their families and not become the subject of a serious or fatal collision on our road network”.
