Your car's horn stops working. A friend offers to connect a small electronic siren to the horn button in its place. What does Minnesota law require?
Correct answer: Repair the horn, since sirens, whistles and bells are not allowed as a car's warning device.
Why
A horn is your quick way to warn another driver, a bicyclist or a pedestrian of danger. Use it when you need it to prevent a crash, not to show anger or to announce that you have arrived. A siren on a private car could make other drivers think that an emergency vehicle is coming. Check your horn when you check your lights, wipers and tires.
