Footage of a lorry driver reversing on the A90 near the Forth Road Bridge has emerged online.
The incident involving a red lorrytravelling against the flow of traffic in the southbound lane is believed to have taken place on Tuesday morning.
The vehicle slowly reverses in the inside lane on the approach to the bridge from Fife, causing a steady stream of cars to have to move to the outside lane.
It is thought the driver realised too late that heavy goods vehicles are not permitted to cross during the day.
The video was filmed near the exit to North Queensferry and ends with a police car approaching the lorry with its blue lights flashing.
It has been viewed more than 10,000 times.
The clip was shared on social media by Fife man Christopher Bain, who wrote: “Couldn’t believe what I was watching this morning feeling shocked at Forth Road Bridge.”
Dashcam footage of a driver passing the reversing lorry along the dual carriageway has also emerged.
The vehicle is seen to the left of the driver on the inside lane of the A90 just before the Forth Road Bridge.
Police Scotland wereunable to confirm what action was taken.
Restrictions on HGVs have been in place since the bridge reopened after a complete closure at the end of last year.
The times that HGVs can cross the Forth Road Bridge were recently extended by an hour-and-a-half. They are now permitted to cross the bridge between 11pm and 5.30am but drivers face a detour via Kincardine at other times.
On Monday transport Minister Derek Mackay said good progress was being made as the bridge strengthening work continued.
He said: “Work to restore the bridge to its full capacity is continuing at pace and this is another step towards that goal.
“The HGV trial has been running for more than a week now and our careful monitoring shows that we can now allow more vehicles across the bridge.”
