In a street with two designated left-turn lanes, from which lane may you start a U-turn?

• A. Either lane
• B. Only the left-most turn lane
• C. Both lanes, unless a sign prevents
• D. None

Answer: (B)

When you’re approaching a street with two left-turn lanes, the lane closest to the center of the road is the one that is typically used for a U-turn, if a U-turn is allowed at all. That left-most left-turn lane is aligned with the space and traffic flow needed to reverse directions safely, giving you a clear path back across the opposing lanes. The other left-turn lane is intended for turning left into the cross street, not for a U-turn, so starting a U-turn from that lane would create conflicts with traffic and those turning left from the cross street. So, if a U-turn is permitted, you begin from the left-most left-turn lane; always obey any signs or signals that prohibit U-turns.
