How many times has that line been used when a relationship was headed downhill to disaster? Communication is important. Communication is very important when you are getting ready to change directions on your bike. The more you let the other drivers know what you are going to do, the less chance there is that they11 do something unexpected and get in your face. Signal your intentions.
When we are slowing or changing lanes, many of us feel that hand-signals are noticed quicker than light- signals by the cars close to us in traffic. A brain picks up motion quicker than light. A recent California law reads that if our bike is equipped with (working) electric signals, then we must use them; we aren't supposed to use just hand signals alone. But we certainly could use both, if we wish ... clicking on the directional signal and then using a hand signal for the drivers near us. Whatever works.
When you are downshifting for a stop or a turn, a couple of flashes on your brake light should wake up the driver behind you to the fact that you are slowing so you don't surprise them; You11 reduce the odds of being mowed down by someone who's not paying attention. And ... don't hesitate laying on your horn if someone near you looks like they might change into your lane without checking their blind spots. Wake 'em up!
Hey! There are a lot of different ways to communicate! Hand Signals; Horn; Directional Signals; High Beams on during heavy daylight traffic; Modulating Headlights; Reflector Vests; whatever fits your style! Communication! It will help us to avoid disaster and keep the Shiny Side Up!
