GREEN BAY, WI -- A new law says all traffic must yield to semi trucks in Wisconsin's roundabouts.

And it doesn't just apply to semis.

In short, Wisconsin Act 139 makes it so all vehicular traffic must yield to any semi or truck 40 ft. or larger when approaching, or in a roundabout, regardless of which lane the smaller vehicle occupies when in the roundabout with the semi.

The law says semi-trucks also legally have as much freedom as they need to negotiate a turn, which often includes cutting into the next lane while turning in a roundabout.
