Gov. Phil Bredesen’s legislative effort to restrict who can get a Tennessee driver’s license is moving through the state Legislature.

The driver’s certificate bill would give Tennessee one of the most restrictive driver’s license laws in the nation, prohibiting some legal immigrants and all undocumented immigrants from getting state licenses, The Tennessean reported.

The House Government Operations and Senate Transportation committees moved the proposal forward this past week.

Under the proposal, a new official document called a “certificate of driving” would be issued to state residents who want to drive but cannot prove they are legally in the country.

The certificate would also be issued to legal immigrants here temporarily, such as students and temporary workers, and would expire along with their immigration documents.

According to the newspaper, the document would be used only for driving and to obtain insurance. The certificate could not be used as official government identification, for example, either to board a plane or to buy a gun.

All other state residents, including legal immigrants here on permanent basis, would continue to receive the current state driver’s license.
