emailed to the dept of the interior

Driving down from Mt. Lemmon in Tucson, Arizona this afternoon, I was doing the legal and safe speed limit when I was passed, at considerable risk to myself and others on the road, on a blind curve by a Department of the Interior vehicle going at a high rate of speed.The license plate on the truck was I255904. Since I as a taxpayer own this vehicle and pay for the driver's salary as well as all pertinent insurance, I would appreciate it if someone would ask him to take more care of public property and less risk with public liability. Please either forward this to the appropriate authorities or send me the information I need to do it myself.

Thank you.
