One Way System to Begin on Saturday 29th.
The one-way system over the Mountain Road will commence next Saturday.
It was introduced in 2007 in an effort to cut down on head on collisions, since it's introduction there's been a drop in fatalities on the Mountain.
Motorists and bikers are reminded however to keep a safe distance from the vehicle in front in the event of an emergency stop.
The road will still be two way up to the Creg Ny Baa pub from Douglas.
The road will go back to normal after the TT finishes on June 11th.
