One way to respond to tailgaters is

1. yelling at them.
2. honking your horn.
3. maintaining a dominant lane position. ✓
4. None of the above

Answer: C. maintaining a dominant lane position.

Maintaining a dominant lane position is one way to respond to a tailgater.

Why this is the answer

The handbook's tailgater strategies include keeping a dominant lane position, usually the left position, so the rider is visible to the driver behind. The passage says this can discourage the tailgater from coming closer, and changing position and then returning to the dominant spot may catch their attention and make them drop back. So the rider's response is about making themselves seen and holding a position rather than reacting at the driver.

Why the other answers are wrong

• A. yelling at them. — Yelling at a tailgater is not one of the handbook strategies and does nothing listed in the passage to make you visible or discourage the driver.
• B. honking your horn. — Honking is not listed as a tailgater response; the handbook instead mentions double-flashing the brake lights to alert the driver.
• D. None of the above — This is wrong because keeping a dominant lane position is explicitly listed as a strategy for tailgaters.

Remember it

Remember: be seen and hold your spot—dominant position is your tailgater tool.
