There are a few different hand signals that cyclists use to communicate with each other while riding. Here are some of the most common:
-Pointing up or down with one arm extended straight out to indicate which way the person is going
-A clenched fist held up in the air to signal stop
-An open palm held out to the side at shoulder level to signal that it is safe to pass
-A pointed finger held up in the air to signal that there is a hazard ahead
Using proper hand signals is important for both the safety of the rider and those around them. It allows people to be aware of what actions the rider intends on taking, and can help avoid potential accidents.
