U-turn cannot be made where:

U-turn cannot be made where:

• A. curbs or grades
• B. where you are not visible
• C. where specified
• D. on a one-way street

Answer: (C)

U-turns are controlled by signs and road markings. You may not make one where there is a posted restriction, such as a “No U-turn” sign or equivalent marking. That’s why the correct choice is “where specified,” because the prohibition is defined by the traffic control device at that location. The other scenarios can affect safety or feasibility, but they aren’t universal prohibitions in the same way a sign or marking that specifies “no U-turn” is.
