RB-15
The no-turns sign (a T-shaped arrow crossed out in a red circle) prohibits all turns — left, right, and U-turns — at the intersection. You may only continue straight through.
Regulatory signs control how you may use the road — they must be obeyed.
Proceed straight. If you needed to turn, continue to the next intersection that allows it. Do not try to beat the restriction by turning from an adjacent lane.
Regulatory signs are usually white rectangles or squares with black or red markings. A few have special shapes: a red octagon means Stop and a red-and-white downward triangle means Yield. A red circle with a slash means something is prohibited.
Don't confuse it with "no left turn" or "no U-turn" — this one bans every turning movement at once.
Road signs are one of the five areas the 30-question Alberta Class 7 knowledge test covers, and the largest block in our mock exam at 8 questions. When you can name this one without thinking, move on to the free Alberta learner's practice test and see how the rest of the exam treats you.
