What is Oregon law regarding horns on a motorcycle?

• A. You must have one horn.
• B. Two horns are required.
• C. No horn is required.
• D. At least three horns are required.

Answer: (A)

In Oregon, a motorcycle must have a working horn to serve as a warning device for other road users. The statute sets the minimum as at least one horn in proper working order, so you’re required to have one horn. It isn’t about having multiple horns, or about having no horn at all—those options don’t match the rule. The practical takeaway is: keep a functional horn on your bike so you can alert others when needed.
