The Mountain Road is one way from Ramsey to Douglas for the duration of TT fortnight.
It was introduced at the Centenary TT in 2007, to try and eradicate head-on collisions.
Inspector Terry Stephen of the Roads Policing Unit says despite the change, people still need to drive and ride responsibly up there:
