Faulty vehicles are being targeted by police officers in random roadside checks.
Around 200 vehicles have been stopped along the A46 at the Vale truck stop in a bid to catch up motorists with dodgy vehicles.
Gloucestershire Constabulary and West Mercia Police teamed up for four hours on Friday evening to carry out the searches.
They were targeting defective vehicles.
Fourteen drivers received prohibition notices for faults on their vehicle that were considered to be a significant road safety concern and six Vehicle Defect Rectification Scheme notices were handed out during the operation to drivers who had faults on their vehicle.
All drivers will be required to have the defects remedied, and attend an MOT testing station to prove their vehicles have had the faults identified by officers corrected.
Two drivers stopped will be required to produce their licenses, MOT and Insurance certificates at a police station within seven days, or face prosecution.
One driver was issued with a fixed penalty notice for failing to display a tax disc and two £1056 fines were issued for the use of red diesel.
Superintendent Rob Priddy from Gloucestershire Police said: "I would like to acknowledge the understanding and cooperation of the vast majority of drivers and passengers that we stopped and inconvenienced.
"They were very supportive of the operation and its aim to make communities in both Gloucestershire and West Mercia safer places to live and work."
