These plates are issued to to pickup trucks, as well as all types of vehicles used for both business and private purposes with a Gross Vehicle Weight Rating up to 12,500 lbs. Up until October 1, 2005, the weight limit was 10,000 lbs.
In 2004, P.A. 04-199 changed the requirements for issuance of combination plates to pickup trucks. Starting June 3, 2004, non-commercial pickup trucks with a GVWR under 8500 lbs could now display regular passenger plates. Before this, ALL pickup trucks had to be registered with Combination plates.
This type started in 1922, with the same size, colors and format as regular passenger plates but with a ‘C’ prefix. “Comb’n” was first spelled out in 1932. At this time, a stacked 2-letter prefix came into use.
In 1940, these plates took on the same look as regular passenger plates of the time, but always starting with a ‘C’ as the first letter. In 1946 and 1947, the same variations which passenger plates experienced were also applied to combination plates – i.e. brass base metal (around the C/4 series), and thin aluminum plates towards the end of the series.
In 1948, plates were reissued on the new reflective yellow scotchlite base. The reflectorization didn’t hold up well, and around 1951 the white scotchlite was introduced. At the very end of this reflective white base, the numbering format was expanded to C/A 1234. This lasted until 1955, when, like passenger plates, black on bare aluminum plates were issued.

Second year for this type.
Near the end of the numbering series.
This plate once had reflective yellow sheeting on the background.
The changeover between yellow and white scotchlite apparently happened between the C/5 and C/7 series.
Again, missing the yellow scotchlite.
Somewhere around a 1948/1949 plate, revalidated until 1956.
