Two light commercial vehicles were seized for having no insurance in a multi-agency operation on the A259 at Peacehaven on Friday (April 26).
Operation Stinger was run jointly by Sussex Police, VOSA (the Vehicle and Operator Services Agency) and HM Revenue and Customs.
It involved checking light commercial vehicles and using mobile Automatic Number Plate Recognition to target uninsured drivers.
Another vehicle was reported for no insurance, two were reported for no MOT and three were given immediate prohibitions for unroadworthy vehicles.
This meant which they had to have work done to address the faults at the roadside before being allowed to continue.
Three heavy goods vehicles were also stopped and two were given immediate prohibitions by VOSA.
Sergeant Richard Trundle from Sussex Police’s road policing unit said: “We stopped 18 light goods vehicles and eight of them were found have some form of problem.
“Potentially, they could have gone on to have been involved in some sort of incident and the consequences could have been very serious.
“This is unacceptable and along with our colleagues in other agencies we will be running similar operations throughout the year, specifically targeting uninsured and dangerous vehicles.”
