When driving in Italy, there a few key things to remember:

• You cannot make a right turn on a red light, even if you have stopped and traffic is clear.
• In certain cities, street names are engraved on the sides of buildings rather than on road signs.  
• When parking in a lot or on the street, most areas require you to pay for a ticket from a parking meter. Place it in a visible spot on your dashboard to avoid parking tickets. 
• Be sure to ask a branch employee what type of fuel your vehicle requires. Diesel fuel is more common in Italy than it is in the US.
