The National Performance Management Measures; Assessing Pavement Condition for the National Highway Performance Program provided in Subpart C of 23 CFR Part 490 permitted the use of PSR as an alternative method for reporting pavement conditions for Interstate and non-Interstate National Highway System locations where the speed limit is less than 40 mph.
