AUGUSTA — Maine Gov. Paul LePage faces a stack of bills he must decide whether he will sign. But one he’s sure to sign will make it a crime to drive a commercial vehicle while on methadone.

Lisa Ronan plans to be in the governor’s office on Friday to witness the methadone bill signing. Her husband, Shannon Ronan, was killed in December 2009 when his UPS Inc. truck was rear-ended by a large utility truck whose driver was taking methadone. Shannon’s truck was forced into oncoming traffic and he was killed instantly.

LePage had about 70 bills to deal with that were sent to him in the closing days the 2011 session, giving him until the end of the week to deal with them. He’s already signed about half of them.
