A horse-drawn buggy is coming toward you on a two-lane road. What does the Driver's Handbook say to do — and what should you do differently if you are passing one from behind?

Correct answer: D. Move to the far right of your lane when meeting one, and give as much room as possible when passing

Meeting one, "move to the far right of your lane"; passing one, "give as much distance between you and them as possible." Both are about the same risk, stated plainly by the Handbook: "Passing too closely could scare or startle the horse, causing it to change direction suddenly on the roadway." An animal is not a machine — it reacts to a close, fast, noisy pass in a way no vehicle does, and the person in the buggy has very little ability to correct it. Horse-drawn vehicles usually travel on the shoulder, but the Handbook notes they "may straddle or enter the paved lane where shoulders are narrow or no shoulder exists — such as bridge crossings," so do not assume the shoulder is where they will stay.
