Police have issued one with a fixed penalty notice
Police say they've already had to stop people trying to go against the one-way system on the Mountain Road, with one person having been issued a fixed penalty notice.
Every year it's made one-way for the TT fortnight in the interests of safety.
The Mountain Road is currently closed as today's racing gets underway.
Inspector Paul Kemp says it's something they have to deal with every year:
Cost of land pushing would-be farmers away from sector
Charity wants to hear from those who've benefitted from oxygen therapy
Festival of Motoring 'dream rides' take place today
Drop-in session offers support for households ahead of rising winter costs
