Legalized recreational marijuana is almost here, and police in Michiana are getting ready for a possible increase in impaired driving.

Police in Roseland are planning a traffic blitz, including a possible checkpoint, on State Road 933.

Officers say there have been numerous fatal accidents on the roadway and they are concerned that fatal crashes could go up if people are using weed and then getting behind the wheel.

Recreational marijuana will become legal in Michigan on Dec. 6, however law enforcement officials on both sides of the state line remind everyone that it’s illegal in any state to smoke it and drive.
