So the other day, I was riding at night and I encountered a runner in the bike lane. He didn't have any reflective clothing, so he was somewhat hard to spot. Anyway, he was in the bike lane, and going with traffic. I didn't know what to do, so I looked back for cars and passed into a traffic lane around him and went back into the bike lane. Is this the proper thing to do? Should I have a bell/horn to warn him that I'm about to pass?
