The Truck legend resumed after a ten year absence, and was
embossed at the bottom of the plate. The serial format was once again Cx-00000
until this was exhausted in 1982; then serial format 00000-Cx was issued on this base
until partway through the CD series. Un-stickered plates used in 1978, 1979 stickered plates, and 1980
stickered plates cannot be distinguished between light and heavy truck usage, unless they also have subsequent
month-year expiration stickers. May expiration stickers were only isused to heavy trucks over 26,000 pounds
G.V.W., while expiration stickers for months other than May indicate a light or medium truck under this
weight.
