A driver went supermarket shopping in a second-hand ambulance with the emergency lights flashing, police said.
The ambulance was reportedly carrying a family when it arrived at the Asda store in the Harpurhey area of Manchester on Wednesday.
Traffic officers tweeted that the group then "promptly went inside to do their shopping".
The ambulance was seized and a man was later charged with a range of driving offences.
The 32-year-old is due before magistrates in Manchester charged with driving while disqualified, without a licence, without insurance, and using a vehicle with unauthorised blue lights.
He also faces a charge of failing to appear at court at an earlier date.
