Senior citizens do need to retake driving tests at regular intervals to ensure that they are able to drive safely. The laws concerning seniors and their driving privileges vary from state to state.
In most states, the licenses of senior citizens are only valid for one to four years at a time. Once their licenses expire, they are usually required to renew them in person. Depending on the state, they may have to undergo a combination of vision tests, written tests or driving tests. In some cases, a case worker interviews or assesses senior citizens and makes a determination as to whether to grant driving privileges.
