Under Oregon law, what is the minimum number of brakes that must be operable?

• A. One brake.
• B. Two brakes.
• C. At least one brake.
• D. All four brakes.

Answer: (C)

The main idea being tested is the legal minimum number of brakes that must be able to function on a motorcycle in Oregon. The correct interpretation is that at least one brake has to be operable. This means the vehicle must have a braking system that can be used to stop, even if the other brakes are out of order. In practice, motorcycles typically have two separate braking systems (front and rear) for safety and redundancy, so you should maintain both in good condition. The other options suggest more brakes than the law requires, or a scenario that isn’t the legally defined minimum.
