It seems so, if you agree to the "Privacy Act and Security Statement".
". . . When logged on to the CARS system, your computer is considered a Federal computer system and is property of the U.S. Government. . . Any or all uses of this system and all files on this system may be intercepted, monitored recorded, copied, audited, inspected, and disclosed to authorized CARS, DoT, and law enforcement personnel, as well as authorized officials of other agencies, both domestic and foreign."
I'm predicting continued silence from both the ACLU and MSM on this one.
