The TSA is attempting to live up to it's name, the Transportation Security Administration, by monitoring our highway system too:
This notice announces that the Transportation Security Administration (TSA) has forwarded the new Information Collection Request (ICR) abstracted below to the Office of Management and Budget (OMB) for review and approval under the Paperwork Reduction Act (PRA). The ICR describes the nature of the information collection and its expected burden. TSA published a Federal Register notice, with a 60-day comment period soliciting comments, of the following collection of information on May 29, 2012 77 FR 31632. TSA received four comments in response to this notice. Two comments were unrelated to the ICR. The remaining two comments were requests for program information. This voluntary information collection allows TSA to conduct transportation security-related assessments during site visits with security and operating officials of surface transportation entities.
