I use signal's all the time I ride, was heading for a stop light, started to signal, then a car pulled up beside me and the driver stated: What does that signal you just gave mean?? I wanted to laugh but didn't and told him it ment "STOP". He was a 20 something and actually didn't know what hand signals mean!! For what it's worth, I've gotten a few smiles from auto drivers when I use my hand signals, think they appreciate knowing where, "I'M" going!
