Today is traditionally known by TT fans as Mad Sunday, a day when many fans enjoy a lap or two of the TT course themselves.
However, this year is different because this afternoon there will be racing on the course.
The Superbike race was put back to today from Saturday to allow for more time for practices.
The schedule for the day is:
1pm: Roads closed, mountain section
1.30pm: Roads closed rest of the course
2.15pm: Dainese Superbike race
5pm: Roads open around the course.
The police have appealed for fans driving or riding around the course this morning to take extra care.
Inspector Derek Flint said: ‘Even though the benefits of the mountain being one way are in place for the entire two weeks these days, Mad Sunday is traditionally a time for that little bit of extra exuberance, which creates us problems when people run out of skill, then run out of road.
‘With a dry and sunny day forecast, we are expecting large numbers of cars and bikes to be out from early doors.
‘We are totally geared up for this, and will be out there at peak strength to quell any over-enthusiasm, and deal with people whose standards of road use fall below the expected standard.
‘The Mountain section of the course is due to close at 1pm, so we expect that people will be making the most of the morning to enjoy it.
‘What needs to be remembered though, is that if we have a collision on up there, then we shut it so we can deal with the scene safely.
If it is a bad one, there is every possibility the police could be the only ones up there from early morning until racing begins.
‘If people want to have a good time, they have to take to the roads in captain sensible mode, otherwise it is going to be an awfully long day waiting around for them, asking the bobby stood doing point duty when the road will re-open.
‘The same applies to the rest of the course, which closes for racing at 1.30 pm.
‘Everything is scheduled to be re-opened at 5pm, and we will still out there pressing home safety until darkness falls. All we ask is for people to stay safe, and keep it real. Mad Sunday doesn’t mean a it’s public racetrack.’
