Placards for vehicles belonging to permanently disabled persons will be phased out starting July 1 and the Department of Motor Vehicles will begin issuing new ones. DMV Director George Meese said that by Oct. 1, only the new placard will be legal. A law enacted last year authorizes the department to set up a computerized roster that can quickly identify the placard owner. It also permits the agency to give each eligible applicant an identification card with a number matching the one on the placard. Placards will cost $6. The department expects to issue up to 400,000 permanent and 10,000 temporary placards by October.
