A bill that would begin a road side drug testing program in Michigan is close to becoming reality. The bill passed the Senate and House on June 9 and would create a pilot program run by the Michigan State police to conduct a roadside saliva drug test for cocaine, marijuana, heroin and other drugs.

The intent of the new law is to allow the state to devise a reasonable standard for drug testing of drivers, just as it has in place for drunk driving.

The bill, which should be signed into law by the governor this month, is named after a couple who was killed in March 2013 by a tractor trailer that ran a red light and slammed into their car. The big rig driver was convicted for driving while intoxicated causing death, and was sentenced to at least 5 years in prison.

The trucker’s blood was drawn after the crash and was found to show THC, which is the key ingredient in marijuana.
