Andrew Caudle Leece, aged 42, of Tynwald Road, Douglas, has been fined £160 for having no vehicle tax.
He was also ordered by magistrates to pay £50 prosecution costs.
Police spoke to Leece after he had been driving a Ford Transit van on the Mountain Road on February 27.
The vehicle’s licence had expired in October 2022.
The court heard that the vehicle was taxed within an hour of the police speaking to the defendant.
He agreed to pay the fine and costs forthwith.
