Bicycles don't come with turn signals and brake lights. Fortunately, there's already a universal language for indicating turns and stops on a bike.
Step 1: Prepare to turn left Learn how to signal a left turn. About 50 yards before the turn, take your left hand off the handlebars and extend it to the left, perpendicular to your body.
TIP: These signals apply to countries where motorists and cyclists drive on the right side of the road. For countries that use the left side of the road, check with local cycling organizations or direct.gov.uk.
Step 2: Turn left Hold your hand open and point it in the direction you're turning. Keeping your arm extended, start riding from the right shoulder of the street to the left side of the lane. Once you reach the intersection, turn left.
TIP: Don't assume that cars behind you have noticed your hand signal. Always glance backwards quickly before you initiate your turn to check for traffic.
Step 3: Turn right Know how to signal a right turn. About 25 yards before you turn right, raise your left hand with the elbow bent 90 degrees, your hand pointing skyward, and your left arm forming an "L." Check for traffic before entering the intersection to turn.
TIP: It's also acceptable to extend your right arm perpendicular to your body to signal a right turn.
Step 4: Stop Learn the signal for a stop. About 50 yards before you come to a stop, raise your left elbow until it is perpendicular to your body. Point your fingers down to the pavement, palm facing the traffic or riders behind you, so your arm forms a reverse "7." Hold this position until you come to a stop.
Step 5: Signal for a group Know the signal for a group of riders. If you are riding with a group behind you, signal drivers in front of you by raising your left hand straight above your head, palm forward.
FACT: Drivers and motorcyclists whose turn signals and brake lights aren't working can also use the same signals.
