Smoking cannabis while driving and not knowing the speed limit are some of the reasons why drivers have been stopped on the M4 this week.

Wiltshire's Roads Policing Unit has been pulling over reckless drivers.

One man was arrested for drug driving and drug possession after he was found to be smoking weed while driving.

A search revealed he had a sizeable amount of cannabis wrapped in plastic in the vehicle too.

 

Wiltshire Specialist Operations tweeted: "RPU did not need the services of this personal security ‘dog handler’ to sniff out the cannabis after this driver was puffing away down the M4 earlier this week."

And in a car seizure, officers pulled over a driver who was swerving all over the M4.

It transpired that the driver had no licence so they then gave false details of a different person with no licence.

Another driver was stopped because he was caught speeding at 107mph.

The RPU tweeted: "The other driver was caught on the M4 and did not know the speed limit for the motorway (mainly because they never took a test!)"

 

This vehicle was also seized.

The officers involved received praise for their actions on social media.

One tweeted: "Great work as always team. Thanks!"
