Drivers have accused fellow motorists of causing longer queues than necessary during roadworks on Tay Road Bridge.
A number of locals have taken to social media to criticise those not using both lanes when traffic is merging on the Fife approach to the bridge.
Resurfacing work has been taking place on the crossing since June.
The roadworks have been largely free from major disruption, but there have been reports of longer delays in recent days.
Many are blaming drivers for moving lanes too early on the A92, south of the bridge, instead of waiting until they are forced to merge.
Drivers ‘don’t understand traffic merging’ at Tay Road Bridge roadworks
In a thread on Reddit, one driver wrote: “What’s with people not understanding traffic merging on the roadworks (at the) Tay Bridge?
“It backs up to the (Forgan) roundabout with everybody queuing in the left lane, blocking people coming down the right.
“That blocks the roundabout behind. Just use both lanes and zip merge like God intended.”
Another driver hit out in a second Reddit thread, writing: “I work in Fife but live in Dundee. A lot of the time I’m coming from the Forgan Roundabout at around 5.45pm.
“Sometimes at this time of the day the left lane is backed up onto the roundabout. For (safety’s) sake, it’s better to take the right lane.
“The signs clearly say ‘use both lanes’ and ‘merge in turn’ but last week a guy pulled out of the left lane into the centre, so I couldn’t continue past… he was clearly really angry and driving erratically at this point, so I pulled in behind him to de-escalate the situation.
“Why are people so against others using both lanes?”
Tay Road Bridge roadworks: Drivers ‘blocking road’
One user of X – formerly Twitter – also called for action against those blocking drivers from using both lanes.
Tagging police and roads officials, they wrote: “When are you going to do something about the idiots who block people from using the right-hand lane on the A92 approach to the bridge?
“Someone is going to get seriously hurt!”
Several drivers responded to the threads to agree.
What does the Highway Code say about merging at roadworks?
Although some motorists can get irate at those driving up an empty lane before merging, the Highway Code encourages motorists to merge as they reach the cones.
Rule 134 says: “You should follow the signs and road markings and get into the lane as directed
“In congested road conditions do not change lanes unnecessarily.
“Merging in turn is recommended but only if safe and appropriate when vehicles are travelling at a very low speed, e.g. when approaching roadworks or a road traffic incident.
“It is not recommended at high speed.”
The Tay Road Bridge roadworks will run until November with a second phase planned next year.
