To signal a left turn, remove your left hand from the corresponding handlebar grip. Extend your left arm out to your side until it's parallel with the ground. Maintain control of the handlebars with your right hand. The National Highway Traffic Safety Administration recommends turning your head to make sure you have a clear path before executing the turn.
There are two different ways to signal a right turn. The conventional right turn signal utilizes your left arm. Extend your left hand out to your side until it's parallel with the ground, then bend your elbow to create a 90-degree angle. Point your left hand vertically to complete the safety signal. An second option entails using your right arm by extending it out horizontally from your side to signal a right turn.
Slowing or Stopping
The slowing or stopping signal can be executed with either your left or right hand. Extend your hand out to your side at a 45-degree angle. Rotate the hand so that your palm faces the following motorist or cyclist. Engage the brake lever while keeping your hand extended. Decrease your speed slowly to avoid being rear-ended.
Group Cycling Signals
Group safety signals are designed to alert fellow riders of your next moves and hazards in the riding path. Extend your left arm horizontally out to your side. Bend your elbow at a 45 degree angle. Point your hand downward to inform the group members you are breaking away from the pack by moving to the left. Execute the signal with your right hand when breaking toward the right. To indicate a pothole coming up on the left, extend your arm downward with your palm parallel to the ground. Rotate your hand in a circular motion. Mimic the signal with your right hand to warn against potholes on the right.
