How can you ensure your safety while riding a bike by using proper signaling techniques?

To ensure your safety while riding a bike, use proper signaling techniques by extending your arm to indicate your intentions to other road users. Signal left by extending your left arm straight out to the side, signal right by extending your right arm straight out to the side, and signal a stop by extending your left arm downward. This helps communicate your movements and intentions to others, reducing the risk of accidents.
