Cowboy wheelclampers who will soon be outlawed could turn their attention to illegal parking ticket rackets, the AA has warned.
From October 1, it will become a criminal offence to clamp on private land as the Protection of Freedoms Act comes into force.
But the AA, which campaigned to have the cowboys banned, said the illegal clampers might try to shift their business to bogus parking tickets on private land.
AA president Edmund King warned drivers to be particularly vigilant about where they park until the October 1 ban takes effect.
The new clamping law applies to England and Wales, but not Northern Ireland. Clamping and towing away on private land has been banned in Scotland since 1992.
Mr King said: "We are delighted that cowboy clampers will have to hang up their clamps in a fortnight. This campaign had become a personal crusade for me over the last decade. The outright ban on wheelclamping on private land is a victory for justice and common sense.
"Too many clampers have been acting like modern-day highwaymen for too long. Many elderly and vulnerable people have been ripped off by these callous cowboys."
He continued: "We have noticed that some of the cowboys, drinking in the last chance saloon, are cashing in before they are finally outlawed so we advise drivers to be particularly vigilant over the next two weeks."
