In which situation is it appropriate to use hand signals?

• A. When driving in low visibility conditions only
• B. When making a right turn
• C. When turn signals may not be visible
• D. When driving at night only

Answer: (C)

Using hand signals is particularly appropriate when turn signals may not be visible. This situation can occur in various scenarios, such as when driving alongside larger vehicles that might obscure the vehicle’s signaling lights or in situations where there are many distractions that could prevent other drivers from noticing electronic signals.

Hand signals provide an additional, clear method of communication with other road users. This is especially critical for ensuring safety on the road, as all drivers need to be aware of each other’s intentions. While hand signals can certainly be helpful in low visibility conditions or during nighttime, they are primarily designed as a complementary method when the regular turn signals might not be effectively seen. Therefore, hand signaling enhances visibility and helps convey the driver's intentions more clearly in such circumstances.
