How do hand signals enhance safety at unmarked intersections?

• A. They reduce congestion
• B. They provide clear direction
• C. They attract police attention
• D. They eliminate the need for signage

Answer: (B)

Hand signals enhance safety at unmarked intersections primarily by providing clear direction to both motorists and pedestrians. At intersections where traffic signs or signals are absent, hand signals serve as a vital communication tool that conveys the intentions of drivers and cyclists. This clarity helps to reduce uncertainty about who has the right-of-way and what actions other road users may take, thereby minimizing the risk of accidents. When drivers and cyclists use hand signals to indicate turns or stops, they foster a more predictable traffic environment, which is essential for maintaining safety in areas lacking formal traffic control devices.

While the other options discuss aspects of road safety, they do not capture the primary function of hand signals at unmarked intersections as effectively as the provision of clear direction does.
