THREE LICENSES IN TWO DAYS

The most serious vulnerabilities appeared in California, where agents managed to complete the process to receive three temporary state driver's licenses within two days using the same fake information. On one occasion, after one agent failed the standard eye test, a second agent stepped in for him, passed the eye test, then handed the successful results to the first agent, who had his photo taken for the license.

Simultaneously, a third investigator was using the same data on another line in the same office; he also was issued a temporary license.

"No one at the DMV noticed that two individuals were simultaneously using the same fictitious name and same fraudulent supporting paperwork," the report says.

And perhaps more troubling, that undercover agent had already received a temporary license a day earlier from a different location, using the same name. On Aug. 20 of last year, the agent supplied a fake out-of-state West Virginia license as verification of identity and managed to get the California license. On Aug. 21, using the same name but a fake Texas license, he got a California license again, even after the clerk noticed the agent had received a temporary license the day before. The agent simply said he'd lost the first license, and the DMV clerk issued a second California license "without questioning the story further."

Other locations that ultimately failed the GAO test: Washington D.C., South Carolina, Arizona, Michigan, and New York.
