And parents have been put on notice that they could face penalties.

Tasmania Police and the Parks and Wildlife Service have reported an increase in complaints about vehicles driving on beaches throughout the North.

The service's compliance officer Michael Spaulding said this included many motorists driving in prohibited reserves that covered beaches and coastal areas.

He said foreshore areas were particularly vulnerable to four-wheel drives and motorcycles.

``The enforcement of these regulations is particularly important in protecting flora and fauna as well as preventing erosion in fragile coastal areas and impacts on Aboriginal heritage,'' he said.

George Town police Inspector John King said there had been a rise in complaints regarding vehicles causing excessive noise near homes.

Motorists driving on public land, including beaches and reserves where vehicles are permitted, must be licensed and have registration.

``Parents should also be aware that under certain circumstances they may be proceeded against for allowing children to operate vehicles without licences and registration in public areas,'' Inspector King said. 

Tasmania Police and Parks and Wildlife Service officers will conduct joint operations over summer to ensure compliance with the law.
