Running with the big dogs

This photo was taken on I-275 southbound near Detroit. Lots of tractor-trailers were present on this highway on a weekday evening. The top speed limit in Michigan for cars is 70 mph, surprisingly allowed even on this roadway in the Detroit suburbs. Michigan however has a lower maximum speed limit for trucks: 60 mph. Ohio and Indiana also have split speed limits on their rural interstates. I like this idea: Even though the trucks generally do go faster than their speed limit, they generally do not travel at 70 mph, which makes it easier for cars to get around the trucks. Also on highways with 3 or more lanes in the same direction, trucks are not allowed in the far left lane. The situation pictured above was a little dicey, because there was essentially no left shoulder, but rather only a high Jersey barrier dividing the opposing roadways. Still, we got through with no difficulties.
