Road Signs and Their Meanings: Reverse Turn
The “Reverse Turn” sign (W1-3) indicates that the road ahead will feature two sharp turns in opposite directions. In other words, you will first turn sharply in one direction (left or right) and then immediately turn sharply in the opposite direction (the distance between the turns is less than 600 feet).
The sign does not indicate gradual curves — the two turns are distinct and tighter and require you to slow down and steer carefully. Where curves are less sharp, you will see the reverse curve sign (W1-4).

The sign typically shows a black arrow bending sharply left and then sharply right (or vice versa) against a yellow diamond-shaped background.
Where You Can Expect to See a Reverse Turn Sign?
You will likely encounter a Reverse Turn sign in hilly, mountainous, or rural areas where the road cannot go straight due to natural terrain. It might also appear before sharp turns around rivers, cliffs, or other obstacles.
The sign is usually posted well before the turns, giving you enough time to prepare by slowing down.
What Should You Do When You See a Reverse Turn Sign?
When you spot a Reverse Turn sign, you should:
- Slow down immediately to a safe speed, even if no advisory speed limit is posted.
- Stay alert for sudden changes in the road’s direction.
- Keep a firm grip on the steering wheel to handle the sharp turns smoothly.
- Avoid passing other vehicles — the road conditions ahead aren’t safe for that.
- Stay in your lane, especially because sharp turns can cause your car to drift if you’re going too fast.
Driving cautiously in these situations will help you maintain control and prevent accidents.
Reverse Turn Sign vs. Winding Road Sign: What’s the Difference?
The “Reverse Turn” sign is often confused with the “Winding Road” sign, but they mean different things.
The Reverse Turn sign indicates exactly two sharp, opposite turns right ahead. The Winding Road sign: Indicates a series of three or more curves (both left and right) that are generally more gradual but continuous over a longer distance. Read more about the Winding Road sign
In short:
- Reverse Turn = Two sharp bends.
- Winding Road = Several curves over a stretch of road.

Understanding the distinction is important because the driving strategy is slightly different. On a winding road, you prepare for a longer section of continuous curves, often adjusting your speed throughout. With a reverse turn, you’re specifically getting ready for two quick, sharp turns that require immediate attention and precise control.
