What does it mean when a lead rider bends their left arm at the elbow, points upward, and swings their arm toward their helmet?

Answer: B — Pull over

When a lead rider bends their left arm at the elbow, points upward, and swings their arm toward their helmet, this gesture signals the group of riders to pull over. The upward motion is a clear communication that all riders should be prepared to make a stop or come to a halt safely at the next opportunity. This hand signal is important for maintaining safety and coordination within a group, especially when navigating traffic or busy roads. Understanding this signal is crucial for all riders in a group to ensure everyone is aware of what to expect next and to minimize confusion. Being familiar with these hand signals fosters better communication and ensures the group's safety during their ride.
