Kilometers per hour isn't used on any US road shields

Though not common in the United States, a speed limit may be defined in kilometers per hour (km/h) as well as miles per hour (mph). The Federal Highway Administration's Manual on Uniform Traffic Control Devices, which provides guidelines for speed limit signage, states that "speed limits shown shall be in multiples of 10 km/h or 5 mph." If a speed limit sign indicates km/h, the number is circumscribed and "km/h" is written below. Prior to 2003, metric speed limits were designated using the standard speed limit sign, usually with yellow supplemental "METRIC" and "km/h" plaques above it and below it, respectively.
The 1995 National Highway System Designation Act prohibited use of federal funds to finance new metric signage.

It depends heavily on for whom. I'd bet for those living outside of the Imperial part of the world it surely is not - it does not even mention the kilometers.
