A trial project was launched by police in Maidenhead on Monday to continue their crack down on metal theft.
Officers will stop every vehicle carrying scrap metal they see while on patrol.
The scheme aims to build a database of genuine scrap metal collectors and prosecute those who are operating outside the law.
PC Kristopher Lovell said when police are called about suspicious vehicles they often find they are scrap metal dealers collecting scrap at the request of the owner of the metal.
"All neighbourhood and patrol officers in Maidenhead are aware of the initiative and will be stopping any vehicles they see carrying scrap metal," he said.
"Genuine scrap metal dealers have nothing to worry about as long as they follow current legislation, however those who are not risk being stopped by officers and facing prosecution."
