Two taxis have been seized and drivers have had their licences suspended in a crackdown on illegal driving in Peterborough.
BBC News reports that Cambridgeshire police said the action in Millfield had resulted in more than 40 taxis and PHVs being stopped and checked, with several warnings handed out.
The two vehicles seized were found to be uninsured and one was in a dangerous condition.
A driver had also fraudulently created their own licence.
There were other breaches of licences too and several vehicles were reported for having tyres that were too worn.
The stops by police also involved licensing officers from Peterborough City Council and examiners from the Driver and Vehicle Standards Agency.
PC Nick Southern, casualty reduction officer, said: "The vast majority of taxi drivers are professionals and help keep the public safe by ensuring their vehicles are safe."
