NSW police say hoon driver laws working NSW'S car hoon laws have resulted in more than 120 cars being impounded and 500 sets of number plates being seized, the state government says. Under the laws introduced in July last year, police can immediately seize an offending driver's vehicle and have it towed to a holding yard where it will be impounded for three months. Officers also have the power to immediately remove an offending driver's number plates at the roadside - and they won't be returned for three months. Under the laws, if people drive their car after their number plates have been seized their vehicle can be permanently confiscated. Premier Barry O'Farrell said on Sunday that car hoon selfishly put others' lives at risk when they drive recklessly. The message to lunatics who treat our streets like racetracks is simple - if you want to keep your car, slow down and obey the law. The laws apply to car hoons involved in police pursuits, caught exceeding the speed limit by more than 45km/h or committing hoon type offences such as an aggravated burn-outs or participating in street races. Deputy Police Commissioner Catherine Burn said the laws were having a big impact, and since coming into force 123 vehicles have been impounded and 513 sets of number plates seized. Traffic and Highway Patrol Command chief, Assistant Commissioner John Hartley, said hoon drivers would not only lose their car or number plates for three months, they could also have their licence immediately suspended, lose points from their licences and receive heavy fines.
