Police stopped what they described as a 'three-wheeled wagon' in Co. Londonderry over the weekend.
In a social media post, published on Monday afternoon, the PSNI attached a photo of a trailer which, officers said, had been travelling for 'several miles' with a rim exposed to the road.
They were alerted to the vehicle by an 'observant driver'.
Officers tweeted: "Road Policing Officers from Maydown stopped this "three wheeled wagon" in Foyle over the weekend after an observant driver alerted us.
"The driver had continued like this for several miles. A Fixed Penalty ticket followed! #KeepingPeopleSafe #PSNI."
