A Milwaukee County deputy is recovering after being pinned under a highway traffic signboard.
The sheriff's office says a semi hit the sign into the median Tuesday night and left it hanging over part of a lane on southbound I-41/94 in Oak Creek.
The deputy tried to move it, but another truck hit the sign and it fell onto the officer.
Other drivers stopped to help.
The deputy is in stable condition.
The driver of the first truck was ticketed. Authorities are still looking for the second truck.
