The signs, measuring 8ft by 4ft, were spotted by planning officers on their way to work and the company was asked to take them down as they did not have a permit.
Instead of taking them down, however, the drivers covered them up with black bin bags and applied for a retrospective permit for the billboards.
In the meantime, to continue advertising their business the company has put a small van on the site in front of the covered up adverts with an A-frame billboard attached to it.
Roy Boschat, who put up the signs, said: ‘In the worst tourist season I can remember we are just a few locals advertising what we do. We are just trying to make a living during these tough times.’
Keith Bray, a compliance officer with the Planning Department, declined to comment on Call A Cab’s latest move but confirmed that they did not need planning permission for the van.
