Hand signals should be used when:

• A. Turn signals are hard to see
• B. Driving over 50 km/h
• C. Driving in rural areas
• D. Only when riding a bicycle

Answer: (A)

Hand signals serve as an effective way to communicate your intentions to other road users, particularly in situations where turn signals may not be easily visible. This could occur, for example, when driving a larger vehicle, such as a truck or bus, where the tail lights might be obstructed or not as easily seen by vehicles behind. Therefore, using hand signals ensures that your intentions to turn or stop are clear to other drivers, enhancing safety and reducing the risk of collisions.

While there may be specific scenarios that warrant hand signals, such as riding a bicycle or driving in a rural area, the primary focus here is on the visibility of your turn signals. The effectiveness of hand signals in ensuring communication is crucial, regardless of speed or specific driving environment, making this choice the most appropriate for the question.
