More Englishy translation of that page:

Drivers report that an interesting radar camera has been installed on Rt. 94.

The camera scans license plates of cars that exceed the speed limit, and a few hundred feet further there's a special display that shows this:

[DW 530GS SLOW DOWN]

I wonder what will happen when a car like this drives down Rt. 94?

The whole thing reminds me of this old XKCD strip
