Special Sign Language
We all know how difficult it gets to communicate with someone while both of you are riding a bike, you can’t shout along the way for your pal to hear you. Since biker gang members spend a lot of time on roads, they have special sign language to communicate with other members.
Some of the hand signals used by the biker gangs are very common such as holding a single finger in the air to let other members know that they have to assemble in a single line. Another example includes tapping on the helmet to inform members that the police are ahead.
