Transport Scotland has warned Edinburgh and Fife drivers to be aware of brand new high-tech speed cameras that are set to be installed to catch motorists 'speeding excessively'.
A variable mandatory speed limit (VMSL) is in place across a 22km stretch of road between the M90 at Halbeath and the M9 north of Newbridge.

More than 200,000 vehicles travel across the section of road every single week, with one in five drivers 'speeding excessively' across the stretch.
The Highway Agency Digital Enforcement and Compliance System (HADECS) camera system will go live between the M90 at Halbeath and the M9 north of Newbridge from May 23, 2022.
The HADECS camera system is a six-camera spot speed system capable of detecting the national speed limit and variable speed limit.
Chief Inspector Mark Patterson, Police Scotland Road Policing, said: "Police Scotland is pleased to work in partnership with Transport Scotland to regulate the flow of traffic approaching and crossing the Forth.
"Key outcomes of Scotland’s Road Safety Framework to 2030 are for drivers to know and comply with road rules and drive at an appropriate speed for the conditions.
"HADECS cameras will enforce the variable speed limit to encourage compliance, improve driver behaviour and should be a reminder to drivers of the importance of complying with the mandatory variable speed limit at all times."
