California is to look at ways of tackling its debt by introducing number plates that display advertising
The idea would allow number plates to scroll a selection of paid for digital adverts on a number plate after a car has been stationery for more than 4 seconds. When the car starts moving again it would revert back to the plate number. Drivers could also be offered the opportunity to have a paid custom message scroll across the plate and the technology could be used to display safety and traffic information.
