CARS used by criminals are being cleared off Huddersfield's roads.
The vehicles are being clamped and later taken away.
All are untaxed and many are thought to be so-called `pool cars' used by criminals.
These cars are old, untaxed, uninsured and with no MOT.
Criminals use them to drive around and then leave them by the roadside for other criminal associates to use.
The keys are usually left inside the car somewhere.
Det Chief Insp Tony Craven, head of Huddersfield CID, said: "It is important to get these cars off our roads and curtail criminals' ability to get around. Clearly these cars present a danger to the public."
Already this week, 34 cars have been removed from Huddersfield's streets and by Friday teatime police expect to have shifted around 55.
Areas already visited by clampers include Newsome, Almondbury, Birkby, Fartown, Deighton, Lockwood, Thornton Lodge and Moldgreen.
Senior traffic warden Bob Armitage said: "People who continue to evade paying road tax are becoming a minority thanks to operations like this.
"We will continue to pursue them and take the vehicles off the road and we are already planning the clampers' next visit."
Untaxed cars being sold at the roadside also face being clamped.
Once a car has been clamped the owner must pay an £80 declamping fee and pay a £120 surety fee.
They then have two weeks to tax the car and if they do they get their £120 back.
If the car is not claimed within 24 hours it is lifted from the street, put on the back of a lorry and taken to a compound in Barnsley.
The motorist then has to pay a compound release fee of £160 plus a £15 a day storage charge.
After 14 days if they do not get a tax disc the car is sold or destroyed.
A DVLA spokesman said: "Most of the vehicles are crushed because they are not roadworthy."
