Speed cameras are to be installed on the A9 in Scotland in a bid to improve safety on one of the country's most dangerous roads.
An average speed monitoring system will be set up to reduce "unacceptable" levels of speeding on the single carriageway between Perth and Inverness.
The A9 is one of Scotland's most notorious accident blackspots, with a high number of fatal crashes every year. A £3 billion scheme has been launched by the Scottish Government to turn 80 miles of the route into a dual carriageway by 2025.
Construction work is now under way to install the new cameras at 27 sites along the road, with the system due to go live in October.
A9 Safety Group chairman Stewart Leggett welcomed the announcement and said speed cameras would help to improve driver behaviour.
Mr Leggett added: "Average speed cameras have proven effective in reducing casualties where they have been deployed and they are a key part of the wider plan to improve the safety of everyone using the A9, both in advance of, and during the dualling of this vital route."
