Sample question from test 4
signs
What movement is prohibited by the crossed left-turn arrow?
- A U-turn only at a railroad crossing
- Passing a slow vehicle in the left lane
- Going straight through an intersection
- A left turn
Answer: A left turn. The crossed arrow depicts a left turn, so the restriction is aimed at that movement. A no-left-turn sign does not automatically prohibit U-turns, passing, or proceeding straight, although other signs or markings may control those actions elsewhere. The manual identifies no-left-turn and no-U-turn as examples of red-slash regulatory messages, which means the pictured symbol must be read precisely. When this sign appears, choose another permitted direction and check for lane arrows or signal indications before moving through the intersection.
