The sign "Curve" indicates that there is a curve in the road ahead. It warns drivers to reduce their speed and be prepared for a change in direction. In Germany, this sign typically appears with an illustration of a curved road and is usually placed before the curve to alert drivers in advance.

When you see this sign, it's important to stay in control of your vehicle and to be aware of the road conditions. If the curve is sharp, you may need to slow down considerably. This sign is especially important in adverse weather conditions, such as rain or snow, where the road surface may be slippery.

Always remember to keep a safe distance from the vehicle in front of you, as the curve may lead to unexpected braking or maneuvering from other drivers. Familiarizing yourself with such warnings helps ensure your safety and that of others on the road.
