MENOMONEE FALLS — Menomonee Falls police on Friday posted photos to Twitter to warn motorists about distracted driving, and the post quickly went viral.

The photos show a car that drove off the side of the road while the driver was checking a cell phone. The guard rail smashed through the front window and out the back.

“This is a consequence of checking a cell phone while driving,” police wrote in the post.

Fortunately, the driver sustained only minor injury.

“Nevertheless, distracted driving can end lives,” police said. “Please focus on the road and drive safely.”
