Winding Road Sign

When we talk about winding road sign, some persons may not be familiar with the name. Some may have seen it on the road but it didn’t spark their curiosity.

But since every road sign is important, you need to understand what the winding road sign means, because sooner or later you will come in contact with it if you haven’t yet. You may also be asked during a road sign test.

Above is the sign we are talking about. Having a close look at the sign colour setting one thing is evident that it is a warning sign.

Winding Road Sign: What Does It Mean

Winding road signs are used in situations where there are three or more curves in the road where each curve is separated by a tangent distance of less than 600 feet. A supplemental distance plaque may be placed below the winding road sign to inform drivers of the distance of the winding section of road.

How It Looks

These signs are typically triangular with a black symbol on a yellow background. The symbol usually depicts a winding road to alert drivers to be prepared for changes in direction and adjust their speed accordingly.

Why Is It Important

The winding sign is important as it wakes the drivers attention by providing valuable information about the upcoming road conditions, helping to ensure safe and smooth navigation through the twists and turns of the roadway. Drivers encountering a winding road sign must be prepared to slow down as the sign designates a section of curved road ahead.

Standards, Guidelines for Use and Guidelines For Placement For Winding Road Sign

According to Alberta Infrastructure and Transportation;

Standard

The Winding Road sign (WA-6) is introduced in advance of a roadway section comprising of three or more curves in succession. Each curve within a winding road section must meet the requirements for a Curve sign as defined in Table 1, included in the guideline entitled Turn and Curve signs. If the first curve is to the right, the right version of the sign (WA-6-R) is used.

If the first curve is to the left, the left version (WA6-L) is used. If the length of a multiple curve road section exceeds 1 km, a Distance tab (WA-28S) may be attached below the sign indicating the length of the winding section ahead.

Guideline of use

In general, the Winding Road sign should only be considered when it is impractical to sign adjacent curves with separate Curve signs. Curves on higher class provincial highways should be signed with separate Curve signs. Curves on lower class roadways with lower traffic volumes are better candidates for signing with a Winding Road sign provided the installation of a combined sign is practical and does not pose safety concerns.

When the speed differential between the speed along any of the curves and the roadway approach speed (i.e., posted speed) exceeds 15 km/h, the curves must be signed separately. The Winding Road sign should only be installed if the successive curves within a candidate section are separated by a tangent of less than 120 m. If the tangent separating the successive curves exceeds 120 m, the configuration must be signed as separate curves, regardless of the roadway class.

Guideline for placement

The Winding Road sign should be installed in advance of the winding roadway section. (one for each direction of travel). Signs should be placed in accordance with the criteria specified in Table 2 included in the guideline entitled Turn and Curve Signs.

Supplementary Information On Winding Road Sign

Winding Road Sign

Winding road signs are essential for promoting road safety, especially in areas where the terrain is hilly or mountainous. The presence of these signs warns drivers to anticipate changes in the direction of the road, encouraging them to reduce speed and exercise caution. Negotiating winding roads requires greater attention and control, as the driver may encounter sharp turns, elevation changes, or other challenges that demand careful handling.

These signs come in various designs, but they commonly feature a black arrow or series of arrows curving to represent the nature of the upcoming road. The color scheme, with black symbols on a yellow background, enhances visibility and ensures that the warning is easily discernible to drivers. Road authorities strategically place these signs in advance of the winding section, giving motorists ample time to adjust their speed and driving behavior accordingly.

In addition to the visual cues provided by winding road signs, drivers should also pay attention to speed limit signs and other relevant traffic regulations. Adhering to recommended speed limits and adjusting speed based on road conditions is crucial for preventing accidents and ensuring the safety of all road users.

In summary, winding road signs play a crucial role in promoting road safety by alerting drivers to upcoming changes in road geometry. These signs are part of a comprehensive system aimed at guiding motorists through diverse and challenging road conditions, ultimately contributing to a safer and more efficient transportation network.
