Did you know about this?
Motorists in a number of U.S. states can be fined for failing to slow down or change lanes when passing parked emergency vehicles.
I’d noticed during my crosscountry drive that a lot of people did it. I just thought they were being either polite or cautious. I had no idea they were being law-abiding. I started doing it as well, just because it seemed like a good idea, but I didn’t do it every single time. Maybe I just got lucky. That tends to be a pattern in my life.
