    IDAHO

    Issuance by county began 1926.
    Twin Falls Co. assigned #36-801 - 47-000, T-4101 - T-5200 in 1930.
    Truck began 1924.  Truck registration figures begin 1921, so highest
    passenger number blocks may have been reserved for trucks 1921-23.
    On 9/16/24, 60,000 pleasure car plates had been issued; Idaho ran out
    of plates and ordered 20,000 more.  When 1944 windshield sticker pairs
    were issued, 1942 plates were to be removed from vehicles.
