Can You Make a U-Turn When There's No Left-Turn Signal and the Straight Light is Red?

[Mendoza]

Whether you can make a U-turn when there's no left-turn signal and the straight light is red depends on two scenarios. If there is a sign indicating that left turns and U-turns are allowed, then you can make a U-turn. If there is no such sign, then U-turns are prohibited. Circumstances under which U-turns are allowed include: Presence of U-turn signals or signs: When there is a U-turn signal at an intersection, you can make a U-turn when the U-turn signal is green. If there is a U-turn sign at the intersection or a U-turn indicator on the lane, you can make a U-turn while ensuring the safety of yourself and others. No U-turn signs but left turns are allowed (no prohibition of U-turn signs or markings): Vehicles can make a U-turn at intersections where left turns are allowed and there are no signs or markings prohibiting U-turns. It is important to note that vehicles must proceed according to the left-turn signal and without affecting the normal traffic flow of other vehicles. If you need to make a U-turn at an intersection with a left-turn waiting area, you can enter the waiting area when the straight light is green and wait until the left-turn light turns green to make the U-turn. U-turns are allowed at dashed lines: Whether it's a white dashed line or a yellow dashed line, U-turns are permitted. For double yellow lines (one solid and one dashed), check if your side is the dashed line. If it is, you can make a U-turn safely; if it's the solid line, U-turns are not allowed.
