Part of the reason I like driving on the Autostrada in Italy is that trucks are speed-restricted. Their speed limit is posted on the back of the truck itself so it's easy for anybody to see if the truck is speeding, and I'm led to believe that the penalty for speeding trucks is pretty severe. This may also be true in other countries; I don't know. It's not the case in the US and I wish it were.
