Washington drivers with a record of drunken driving could be required to have special license plates designated with the letter Z.
Legislation introduced by Rep. Norma Smith of Clinton would require that drivers pay an additional $100 for the Z-plate, which would be good for three years. The drivers would be allowed to drive only vehicles with a Z-plate.
The Z would appear as the last symbol at the end of any sequence of license plate letters and numbers.
Motorcycle riders with a drunken-driving offense also would be required to have a Z-license, but the charge would be only $25.
