Two Road Signs That are Easy to Mix Up
Can you tell them apart?
The symbols on these two road signs sometimes create confusion. New drivers often mix up the “Slippery When Wet” sign with the “Winding Road” sign.
For your driver exam, it is important that you can tell them apart and know what both signs mean.
Slippery When Wet
The Slippery When Wet sign is used to warn of unexpected slippery conditions. This usually means that a part of the roadway becomes more slippery in wet or cold weather.
Expect to see the sign close to bridges and overpasses, which freeze first in cold and wet weather. Bridges and overpasses also dry out last. In wet or cold weather, you must slow down and drive with caution.
Signs may emphasize the risk by a supplemental plaque with a legend such as ice or when wet.
Plaques with the words “Steel Deck” or “Excess Oil” are also used to indicate other reasons for slippery conditions.
Such signs can be orange (work zone) or pink (incidents) to indicate a temporary condition.

Reverse Turn – Reverse Curve Signs
When there are two turns or two curves ahead, you will typically see the yellow Reveres Turn or Reverse Curve sign. These signs tell you to slow down and be prepared to turn first to the right or left, and then in the opposite direction.
When you approach any of the signs above, you turn left and then right.
When there are more than two turns or two curves, you will see the Winding Road sign. Turns or curves on this roadway are normally separated by less than 600 feet.
You may find an advisory speed plaque below the sign. For safe driving, you should always slow down to the recommended speed. In adverse weather conditions, you should slow down even more.
There may also be a distance plaque, telling you how many miles of winding road you should expect ahead.
You may also see repeated Winding Road signs along such a roadway.
Will These Signs Be on Your DMV Written Test?
Yes, since they cause confusion for many new drivers, there is a great chance you will see one of these signs (or both) on your test.
