May a motorcycle legally share a lane with your vehicle in California?
-
A.
Yes, and the manual calls it lane splitting Correct
-
B.
No, motorcycles must always have the full lane
-
C.
No, unless traffic is fully stopped
The answer is "Yes, and the manual calls it lane splitting"
California law makes lane sharing with motorcycles legal, and the manual calls the practice lane splitting. Choice B reflects a driver's instinct to treat one vehicle per lane as an absolute rule; the manual prints both 'give the motorcycle the full lane' and 'lane splitting is legal' in the same section, and only the first is a courtesy.
The traps in the wrong answers
B. No, motorcycles must always have the full lane
The full-lane practice is a courtesy in the same section, not a legal requirement that bars sharing. This answer reads the 'give the motorcycle the full lane' courtesy as if it were the rule, missing the sentence beside it that permits sharing.
C. No, unless traffic is fully stopped
The manual attaches no traffic condition to lane splitting and does not restrict it to stopped traffic. This answer invents a traffic-flow condition the manual does not print, borrowing a rule of thumb from stop-and-go freeway driving.
