Motorists "breaking the lights" at road works in Ballybofey are committing an offence, Donegal County Council has warned.
As a result the Council is appealing to drivers to obey the traffic signals "for their own safety and for the good of everybody trying to get around."
The warning comes as "essential roadworks" along the N15 south of Ballybofey to the Cappry road junction (Roadhouse Bar) continue.
A council spokesperson said they were aware that this was "causing significant disruption and delays" to motorists.
The spokesperson added: "The works are being carried out on/or adjacent to the existing road and therefore significant disruption and delays are unavoidable.
"In addition, traffic volumes on the N15 can be quite significant at times through Ballybofey and Stranorlar and there is no reasonable or safe alternative or diversion route available for this location.
"For this reason we are appealing to motorists to obey the traffic signals for their own safety and for the good of everybody trying to get around.
"Drivers breaking the lights is the single biggest problem effecting the current traffic lights arrangement. It is an offense to do so and has significant knock on effects.
"The traffic management contractor for this project is local to the site and is on 24-hour call.
"They, with the Gardai, attend and address issues arising as soon as possible.
"This includes resolving any issues arising out of driver behavior, faults, accidents or incidents.
"Once a problem occurs significant tailbacks rapidly increase and unfortunately it can take some significant time to resolve and clear tailbacks.
"This has resulted in some very considerable delays arising on occasions.
"Again we are sorry for the inconvenience that these works are causing but they are essential and we are asking all motorists to bear with us, obey the traffic signals and allow extra time for journeys."
The spokesperson concluded: "Thanks to all your patience and co-operation."
