random stops or roadblocks? Canada (BC at least) does roadblocks.

  The road is not actually physically blocked, but every vehicle that comes on that road is hailed to stop for the test. If someone takes a U-turn to avoid the test, there's typically a motorbike or a patrol car ready to chase.

    The U.S. does this too. Happens maybe once a month around San Jose, for example. Usually you can avoid it because Google Maps detects the huge back-up and routes you around it :) if you know what to look for (half-mile stretch of red traffic in a place where that's not the norm on a week-end evening), it's generally not hard to spot.
