What should you do if you lose sight of the guide while backing?

• A. Tap the horn
• B. Stop immediately
• C. Adjust your mirrors
• D. Slow your reversing speed

Answer: (B)

When backing, you must have a clear view of the guide and the area behind you. If you lose sight of the person guiding you, the safest move is to stop immediately. This stops the vehicle before you drift into an obstacle or into the guide’s path, and it lets you re-establish communication and visibility—either by re-seeing the guide, moving to a position where you can see them, or having the spotter guide you from a better angle. Tapping the horn won’t restore visibility or communication, adjusting mirrors while still moving won’t fix the immediate risk, and slowing down without stopping still leaves you without a confirmed view of your surroundings. Stop to reassess, then proceed only when you can clearly see and coordinate with the guide.
