Via Verde (literally "Green Lane") is an electronic toll collection system used in Portugal since April 1991.

If an exception is detected (the tag is invalid (or non-existent) or the vehicle's class (as detected by the lane sensors) does not correspond to the class encoded in the tag, amongst others) the vehicle is photographed and, if there is indication of fraud, a legal procedure is initiated.

Many carparks, some gas service stations (GALP) and even McDrive (equivalent to DriveThru) are now using it as a possible payment method.

Since 2010, some highways have used a system of electronic tolling – no manual cash or credit card payment is possible anymore.

These highways can be recognized by an icon showing a car driving under some curved lines and a Euro symbol.
