Oregon law requires headlights to be on at all times and limits the number of white headlights to between 1 and 3. What is the maximum number allowed?

• A. One to three
• B. Two to four
• C. Three or more
• D. One only

Answer: (A)

Oregon sets a range for white headlights: you must have at least one and no more than three. So the highest number you may legally use is three. That’s why the description of the allowable range as one to three is the correct choice—the upper bound of that range is the maximum. If you were thinking four or more, you’d be over the limit; if you thought it had to be only one, you’d understate the allowed range; if you thought three or more, you’d exceed the maximum.
