The county council increased its potholes repair team
Motorists in Gloucestershire are being urged to obey stop and go signs after safety concerns for road workers.
Road repair teams in the county have been increased to fix potholes caused by freezing weather in January.
Operations manager Chris Panes said a "significant minority" of drivers were ignoring the signs and putting workers at serious risk of injury or death.
Offenders can be issued with a £60 fine and three points on their licences or can be summonsed to court.
Mr Panes said there had been a number of "near misses" as a result of motorists driving through stop signs.
"I realise that roadworks are inconvenient and can be frustrating but the stop-go signs are a quick and effective way to control traffic while maintaining the safety of our workers," he said.
