This Memorial Day weekend is officially the beginning of summer, and traffic is expected to be heavy.

Local law enforcement will be on high alert watching for aggressive and drunk drivers.

Lt. Tim Carnahan with the Wisconsin State Patrol believes because of the economy, many travelers may hit the highway instead of flying to their holiday destination.

And unfortunately there are more roadway accidents on Memorial Day weekend.

"There tends to be. There's a spike as you can imagine with that much traffic you're gonna have more opportunity, if you will, to collide with somebody else," Lt. Carnahan said.

According to the state Department of Transportation, a person is killed or injured in a speed-related crash in Wisconsin approximately every 47 minutes.

Troopers will enforce 'Click it or Ticket,' and encourage all travelers to buckle up.

They'll also be on the lookout for speeders, tailgaters, and drunk drivers.

If you notice an erratic driver it is okay to pull over, call 911 and report them.
