How far before making a turn should you begin signaling on a motorcycle?

Answer: C — 100 feet

When riding a motorcycle and preparing to make a turn, it is essential to signal in advance to inform other drivers of your intentions. Signaling at least 100 feet before making a turn gives other road users enough time to react to your upcoming maneuver. This distance allows vehicles behind you to adjust their speed and position, enhancing overall safety on the road. Additionally, signaling early helps prevent sudden lane changes and reduces the risk of accidents. Therefore, signaling 100 feet before making a turn is the correct choice.
