Scotland’s main transport body insists there are more than enough signs to let drivers know of average speed cameras on the A9 Perth to Inverness road.
Transport Scotland were reacting to claims from motorists who contacted The Courier to complain of a lack of signage for the speed cameras.
They were installed in October as £3 billion work continues to dual the length of the road.
One motorist, Iain Sommerville, said he travels on the A9 almost every day from Pitlochry to Perth but feels there should be more signs to let drivers know when they are about to approach the speed cameras.
He said: “My main worry is that there are no or very few signs to let visitors and tourists know what the average speed should be, and that if there were more signs it will make it even safer.
“I can honestly say the speed, driving and awareness of drivers has improved since the cameras went up, including mine.”
A spokeswoman for Transport Scotland said that recently-published performance data showed the cameras have been successful in improving driver behaviour, but stressed there is a “comprehensive signing regime” in place for the A9 average speed camera system.
