HARRISBURG (AP) — Pennsylvania is closer to complying with a federal law that requires people to prove they are legal U.S. residents in order for their driver's licenses to be valid for federal purposes.

The state Senate voted Tuesday 49-1 to approve a bill directing state government to comply with the 2005 Real ID law. The bill still requires House approval.Residents wouldn't be forced to obtain a so-called Real ID, and the bill would allow the Department of Transportation to continue producing driver's licenses and photo identification cards that don't meet the heightened standard.Pennsylvania faces a June 6 deadline to become compliant for Pennsylvania licenses to be sufficient to get into federal facilities, such as military bases. Next year, Real ID's heightened standards kick in for people boarding commercial airliners.About half the states are compliant.
