Pleased with the revenue from roadside speed cameras, the Port Authority in La Spezia, Italy has announced plans to expand the use of speed cameras to the sea. Although current law provides no specific speed limit for boats -- ships are to travel at "safe speeds" -- the cameras will be used to issue fines for whatever the officials deem to be excessive.

Italy has been aggressive in its use of the technology. In March, the Italian government hired top Australian model Megan Gale to become the spokesman for the country's land-based photo enforcement efforts.
