In an effort to crack down on distracted driving, and as part of distracted driving month, MPS is getting into unmarked cars and acting as ghosts in "operation ghostrider."

It's not easy when troopers are in marked cars.  People tend to drive a lot more carefully when they see a police officer behind them or on the freeway.

One policer officer said that even if they're doing nothing wrong and we're just driving behind somebody, you' ll see them checking their mirror, and getting nervous.

That's why MSP has started operation ghostrider.  If a police officer rides around in an unmarked car, drivers may not notice and won't put their phone down.  That makes catching them a lot easier.  Here's more from WILX-TV 10.
