Officers from the roads policing team are carrying out operations on dangerous roads in different parts of the county throughout this week.
The A303 was the first port of call because it has had the highest number of deaths and serious injuries related to crashes over the last year.
In just two hours on Wednesday morning, officers arrested a 40-year-old man on suspicion of driving whilst under the influence of drugs and being in possession of cannabis, and issued 10 traffic offence reports along with two for mobile phone use.
The suspect has since been released under investigation. The highest speed spotted by police between 8.30am and 10.30am was 110mph. Police seized two vehicles for not having a licence to drive while other motorists received advice about how they drive and their vehicle's condition.
A/PS Ben Cox, of the Roads Policing Unit, said: “We are pleased to be showing our support to Project EDWARD with both a show of enforcement on some of Wiltshire’s most dangerous roads and also by educating all road users, which includes cyclists and pedestrians.
“While we are constantly out patrolling the roads of Wiltshire to ensure that everyone is using the roads safely, action weeks like this help to really highlight some of our key messages to road users.
“A big focus is the fatal four factors and too often we are stopping drivers for speeding, using a mobile phone whilst driving, not wearing a seatbelt and drink/drug driving.
“These are all incredibly dangerous and increase the risk of an accident being fatal and having devastating, life-changing impacts on not only the victims but their families, friends and the wider community.
“We hope that by targeting some of the well-known hotspots with enforcement and education, we can help to make our roads safer and most importantly, save lives.”
Wiltshire Police is supporting the national road safety campaign Project EDWARD (Every Day Without A Road Death).
Some of this activity will have a focus on the fatal four factors that significantly increase the risk for road users to be seriously or fatally injured if involved in a collision – speeding, using a mobile phone whilst driving, not wearing a seatbelt and drink/drug driving.
Project EDWARD is hosting a virtual road-trip in which they speak to a variety of organisations, experts and projects about road safety, with the road-trip making a stop at FleetCheck’s headquarters in Malmesbury this Friday to look at how fleet management software can help in managing road risk.
