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:
Cannan administration 'at its weakest point at the moment'
Tim Crookall spoke to the media for the first time earlier this week since his reappointment to DOI
Braddan Commissioners says rates increase will 'strengthen' essential services
Chair Neal Mellon says budget is 'prudent' and 'community focussed'
Island's bathing waters meet highest European standards
Eight beaches graded as either 'excellent' or 'good'
Public sector NDAs only confidential between involved parties, says solicitor for AGC
Philip Farrar says any line to the contrary would make them 'void'
