"No smiling".

No more happy days for licensing, the states have declared, drivers must adopt "neutral facial expressions. (source)Many other states are considering similar approach. Some states though are resisting the movement. Pennsylvania Transportation Department spokesman Craig Yetter, states, "People can smile here in Pennsylvania."
