So how do you signal to car drivers that you’re pulling out to avoid parked cars? I use the turning right signal for two reasons – firstly that is what was taught in cycling proficiency when I was a nipper, and secondly because that’s what drivers will understand. After all, cars only have one set of indicators for all actions of this nature.
So if you’re otherwise using roadie signals, and you indicate right to simply move out, this would confuse other roadie cyclists that you are actually turning right. But if you instead use the arm behind the back signal, the car drivers won’t understand you and run into you. Paradox?
