Six taxis were ordered off the road because of concerns about faults in a crackdown on dodgy drivers in east Leeds.
A further 11 vehicles were seized and four clamped for not being correctly taxed in the operation by police and other organisations in Swarcliffe and Whinmoor.
During the two-day initiative 14 out of 100 vehicles that were checked were ordered off the road until repairs had been carried out and and MOT had been passed.
Five drivers were fined for having no excise licence or insurance.
The initiative was welcomed by residents when details were given on Facebook.
Joy Shaw wrote: “Good. I don’t want one of these clowns crashing in to me and all the hassle it would cause with the insurance.”
Andrew Murphy added: “Great policing, quick crime solving with guaranteed closure.
“To make things even better it increases our road and public safety.”
The crackdown was part of the wider Operation Champion – aimed at dealing with issues in specific neighbourhoods.
Police visited 800 houses to and out crime prevention advice and given out crime-prevention equipment including fake televisions, shed alarms and driveway sensors.
Sgt Vicky Cocliff, of the Outer East Neighbourhood Policing Team, said: “This operation was about tackling issues that really matter to our local communities.
“Prevention is better than cure and by meeting people and speaking to them about how best to protect their property we can help to further reduce crime in the area.
“And by handing out free crime prevention tools we are making life even more difficult for criminals in the area.”
As part of the operation, six locations were selected where officers along with staff from HM Revenue and Customs, taxi licensing and the government’s Vehicle and Operator Services Agency (VOSA) could check vehicles.
The off-road motorcycle team went on patrol, carrying out nearly 100 speed checks.
Three warning notices were issued to riders for travelling in an anti-social way.
The Leeds anti-social behaviour team also went on walk-about to deal with issues being raised by residents.
More than £400 in previously unpaid fines was also recovered from people who had been dodging payment.
Similar initiatives take place across the city at regular intervals.
“By working together with partners we can ensure we make the maximum impact to make our communities safer and to help residents to feel safer”, added Sgt Cocliff.
