Drivers in Sheffield who try to speed up their journeys by nipping through bus lanes and tram "gates" face tough action from Monday.
Motorists using bus and tram lanes will face a £60 fine in Sheffield
Managers at Sheffield City Council are using CCTV cameras pointed at the bottlenecks to catch motorists using public transport lanes.
Enforcement starts at Hillsborough Corner and will be rolled out across the city.
Errant drivers will be fined £60 for each offence.
About 5,000 motorists are estimated to abuse the restrictions each day.
They are being blamed for causing delays to public transport services across the city, particularly during rush hour.
A publicity campaign "Free the Sheffield Bus and Trams" has begun to reinforce the message across the area.
Councillor Bryan Lodge, who is responsible for transport in the city, said: "We are one of a group of authorities leading the way on this type of enforcement, which has previously only been allowed in London.
"The levels of abuse across the city's bus lanes and bus and tram gates lead to significant delays for thousands of people using the network.
"We will be taking a tough line to enforce this, but motorists will be given warnings in the first couple of weeks before fines are issued."
The hours of operation of the bus and tram gate at Hillsborough Corner will also be relaxed from 24 hours-a-day to 0700 - 1900 on Langsett Road and Middlewood Road.
Mr Lodge added: "This isn't a money-making exercise - any revenue will be directly re-invested in the enforcement process.
"We just want drivers to respect the restrictions, which are there for a good reason, and keep the city on the move."
