The red light signals drivers to stop and approach the intersection cautiously. It warns them to be aware of potential issues with traction, such as wet or icy surfaces that can cause skidding and accidents.
Drivers should pay attention to this traffic sign and adjust their driving behavior appropriately, reducing their speed and maintaining a safe distance from other vehicles to prevent skidding or being involved in an accident. They may also need to be prepared to adjust their braking and steering to account for decreased traction due to the slippery road surface.
