Truck Plates

This page is a new endeavor. When this website was started almost 15 years ago, I never planned to do anything but current plates. As that goal became reachable, the site was expanded to several groupings of older plates. And so it continued to grow until almost every type except older passenger and trucks were included. That said, I'm going to need much help and many photos.

Truck / Commercial, 1914 to present

Description / History

Comments, what's needed?

1914, this was the first year for state issued truck plates.

Plates were white on black porcelain.  Serial number from 20000 to 39999 were reserved for trucks, and cars with solid rubber tires, but only some 6000 were issued.  Aluminum weight strip on left with 1 to 5 stars indicating the weight rating.  PENNA over the makers number on the aluminum keystone over 1914 on left side of plate.  Issued in pairs.  Plate size is 6" by 15¼".  Manufacturer was Brilliant Manufacturing Co., Phila., PA.

1916 Truck

Plates were black on orange painted steel.  To the left side of the serial number PENNA embossed over embossed keystone. Maker's number was stamped into the keystone.  1916 embossed below keystone.  An aluminum keystone was only used if the plate was transferred to another vehicle.  On the far left were 1 to 5 stars arranged vertically indicating the weight rating.  Issued in pairs.  Manufacturer was Brilliant Manufacturing Co., Phila., PA. 

It appears that truck and solid rubber tire vehicles plates were generally in the 20000 to 29999 range, however, truck plates outside of this series are known.  Nominal measurements are considered 6" by 16", actual measurement is 6⅛" by 16⅛".

Nominal measurements are considered 6" by 14" and 6" by 16", actual measurement of the larger plate is 6⅛" by 16⅛".

1920 Truck
