WASHINGTON, Feb. 18 (UPI) -- All but six states have complied with federal requirements to seek an extension of the deadline they face for implementing more secure driver licenses for U.S. citizens or legal residents only under the REAL ID Act.

The list of state governments falling into line in the past couple of weeks includes former hold-outs like New Jersey and Washington, according to documents posted on the Web Friday by the Department of Homeland Security.

New Jersey filed for an extension after Homeland Security Secretary Michael Chertoff personally called Gov. Jon Corzine, according to one account.

Of the six states that have so far not filed, only Delaware was expected to ask for an extension by the May deadline, according to Brian Zimmer, president of the non-profit lobby group Coalition for a Secure Driver's License.

Zimmer said the governors of Maine, Montana, New Hampshire, Oklahoma and South Carolina "appear to have turned their face against implementing the law" -- setting their citizens up for additional document requirements at airports and federal buildings.
