Sometime, probably about 1979 , as an O/O, I was following 3 LTL trucks down 17, I believe it was (Four lane, divided, limited access). Paper logs, of course. Hadn’t slept in about 2-3 days. Watched first one go under the underpass, no problem. Watched the second, no problem. As the third went under I realized the sign said 12’! And the LTL trailer was 11 1/2’! Or, as my hazy memory remembers it- all I knew was I was 13’6”!!!!
I slammed on the brakes, slid to a stop on the shoulder, short of the underpass. Had to back up over a mile, probably more like 2, to get to an exit. Went back north to the Thruway…… Man- those were the days!
