Average speed cameras installed along a section of Scotland’s longest road will be switched on at the end of the month.
The A9 Safety Partnership announced that the controversial go-slow zone, between Inverness and Dunblane, will start on Tuesday, October 28.
The £2.5million project has seen bright yellow camera units set up at 27 sites along the A9 route.
It is part of a wider package of measures aimed at improving safety along the busy trunk road. More than £50million has already been invested in safety and structural improvements since 2007.
Critics have argued that the cameras won’t do enough to prevent bad driving on the A9.
However, a campaign group called A9 Average Speed Cameras Are Not The Answer has called for alternative measures to address reckless overtaking.
In the run-up to the switch-on, the safety partnership is launched a campaign to raise awareness of speed limits along the trunk road.
Group chairman Stewart Leggett said: “Average speed cameras encourage motorists to improve their general driving behaviour by reducing excessive speed and we are already seeing this on the A9 where the number of people going over the limit is falling without the cameras even being operational.”
