The roads open car leaves the Grandstand at the end of each practice or race session to confirm the course is open to traffic again, but each section remains closed until the car has passed.

Police say the biker will be dealt with firmly as the overtake means they were travelling on closed roads.

The incident comes just a day after a spectator entered closed roads at Crosby, resulting in a four-week prison sentence and an exclusion order.

The rider of this motorbike, a 44yr old man from Stoke on Trent, will be appearing at Court tomorrow.

A UK man who overtook the roads open car on his motorbike this week is warning other riders to be careful after he was prosecuted at Douglas Courthouse.

44 year old Jason Horn of Blurton in Stoke-on-Trent admitted riding on closed roads and was fined £400 with costs of £50 by magistrates.

The court heard he'd handed himself in to police after an appeal social media, and hadn’t realised what the roads open car was.

After his conviction, he told Manx Radio he felt lucky not to have been jailed.
