A crackdown on illegal delivery drivers resulted in five vehicles being seized.
Officers from Kent Police and the Home Office checked whether people had the proper documentation and insurance.
They stopped a total of 28 drivers using cars or scooters on Friday, October 25.
Five vehicles were seized over insurance issues while seven people were reported for traffic offences including not having a licence or MOT.
Delivery drivers are required by law to have business insurance, which traditionally costs more than the standard agreement.
A 38-year-old woman from Ramsgate, who was not a delivery driver, was also arrested during the evening, on suspicion of drug driving and driving without insurance. She was released on bail pending further enquiries.
Sergeant James Cattermole said: “People who regularly use vehicles on public roads as part of their job should ensure they are fully aware of legislation surrounding driving for a living.
“If they are not insured, they present a risk to themselves and others if a collision takes place.
“Like all road users, they have a role to play in keeping the roads safe.
“It is important during the colder wetter weather that they carry out regular checks on the vehicles to ensure they are kept in a roadworthy condition.
“Taking the time to check lights and brakes, and making sure they have the correct business insurance can mean the difference between working or watching your vehicle get seized and a trip to court.”
