Some disabled people use a special card when they park their cars. These are called disabled placards, which are removable signs that can be hung from the rear-view(后视) mirror of a car. These placards are only supposed to be for disabled people.
These placards are meant to help disabled people in a number of ways. They allow the person to park in special parking spaces. They can also be used when disabled people are being dropped off or picked up. Disabled people can even use them to park without having to pay.
Parking officials think that some people are cheating. Not all people who have these placards are disabled. Today, one in sixteen drivers in California carries the sign. There are a lot more people who have disabled placards today than ten years ago. An official from the DMV(加州车辆管理局) says that there are many reasons for the increase. As people get older, they may develop health problems and need to have one. There are also other reasons why more drivers have them today. Finally, there are a number of people who have them that should not.
Last year the DMV cancelled more than 25,000 permits. They found that lots of people who had the disabled placards had died. These permits are no longer valid.
Some people are worried that the system is being abused. They are worried that access to the program could be limited because of the misuse. More rules could make it harder for people with real disabilities to get these placards.
