Safety checks on commercial vehicles — trucks or cars used for business — started today, officials at the Maine Department of Public Safety said.

Roadcheck 2008 is a national law enforcement endeavor that promotes the inspection of such vehicles. The checks will span three days, including today.

Troopers and motor carrier inspectors will check commercial vehicles at the York and Kittery weigh stations. There will be additional patrols performing checks on the turnpike and Interstate 95.

More than 3,000 commercial vehicles were inspected by Maine State Police last summer.
