A bill to amend title 23 of the United States Code to permit States to monitor certain Federal-aid primary roads with speed limits less than 55 miles per hour for purposes of determining compliance with the national maximum speed limit.

Permits States which have a general speed limit less than the national maximum to monitor (for purposes of compliance with the national 55-mile-per-hour speed limit) Federal-aid primary highways posted at less than a 55-miles-per-hour.

Directs the Secretary of Transportation to apportion previously withheld Federal funds to any State from which they were withheld for failure to comply with enforcement of the national 55-mile-per-hour speed limit, if such State is now found to be in compliance.
