Two fives = double nickels = 55 mph. Specifically the hated national speed limit imposed in the US by the 1974 Emergency Highway Energy Conservation Act, kept on the books until 1995. Truckers loathed it because it tanked their delivery times and revenue, and 'doing the double nickels' became code for crawling along under the federal limit just to avoid a ticket.

“Smokey thick through this stretch, better drop to the double nickels till we're past the scales.”
