Two sets of solid double yellow lines spaced two or more feet apart are treated as:
-
A.
A barrier you may not drive on, turn across, or U-turn across except at designated openings Correct
-
B.
A carpool-lane divider that may be crossed at any point to enter or exit the HOV lane
-
C.
The same as a single set of double yellows, which drivers may cross to enter a driveway
The answer is "A barrier you may not drive on, turn across, or U-turn across except at designated openings"
Two sets of solid double yellow lines spaced two or more feet apart form a barrier that drivers must not drive on, turn left across, or U-turn across, except at designated openings. Choice C tempts drivers who lean on the rule of thumb that double yellow only forbids passing (so a driveway crossing must be fine) and miss the separate case the manual carves out when the two sets sit two or more feet apart.
The traps in the wrong answers
B. A carpool-lane divider that may be crossed at any point to enter or exit the HOV lane
The two-set spacing defines a barrier crossable only at designated openings, and the manual marks the edge of a carpool lane with double solid white lines, not yellow. Reads any wide painted yellow divider along an HOV lane as the carpool boundary and assumes HOV lanes admit drivers wherever traffic opens up, instead of only at the designated entrance the manual requires.
C. The same as a single set of double yellows, which drivers may cross to enter a driveway
The manual singles out the two-set marking as a barrier; the driveway and U-turn exception belongs only to a single set of double yellow lines. Leans on the rule of thumb that double yellow only forbids passing, so extends the single-set driveway exception across the two-set barrier as well.
