State Police

Undated, narrow dies
Private ALPCA collection


Issued to State Police vehicles. Instead of white characters, they use yellow., as well as a significantly darker background on some plates (like this one). Supposedly a lower number desginates a higher-rank officer, but I'm not sure if that's accurate. This is a slightly older style, as current base SP plates do not have the maple tree.

As low as it gets. This is the current SP style, with different fonts. However, the bottom corners are cut a little strangely on this plate, so I don't think that's standard procedure.

10 years newer than the last one. The colors are the same, but the font on the top and bottom rims has changed.

Apparently there are some S000 series plates floating around. This plate was on an unmarked Ford Explorer (which is pointless because it has these plates), I also saw S series State Police plates on a Toyota Tacoma. Maybe this series is only for unmarked vehicles?
