A testament to Connecticut’s industrial past; these plates are used on vehicles which are largely confined to operation within large industrial mills and manufacturing complexes, with limited on-highway use.

The fee for these plates is based on the distance of public road traveled – measured in increments of 200 feet.

This type started in the mid-1920s, with a “FAC” legend slanted downwards on the right side of the plate after the serial number. The type progressed through the years on various bases; in the 1950s the plates were 6×9, black on silver or aluminum, with “FAC” stacked vertically after the serial number. Eventually the plates were made in the red on white seen below, and have remained of the same basic design as Commercial plates.

When Factory plates were reissued on the new base plate in 2000, a number of the “F” types (Factory, Farm, Fire Apparatus) were made with blue numbers instead of red. Presently, this type appears on the “Blue fade” base with red numbers, and “Factory” screened below the lower bolt holes.

Reference: Chapter 246 Sec. 14-49 (l); 13a-117.

Prior to this, blue on white plates were used.
