The traffic sign for a traffic jam is typically depicted with a symbol showing vehicles in line or a static image that represents a queue of cars. In Germany, this sign indicates that there is congestion ahead, which may lead to delays in travel.

When you see this sign, you should be prepared for potential stop-and-go traffic. It's important to stay alert, maintain a safe distance from the vehicle in front of you, and be ready to respond to sudden halts or changes in traffic flow.

Additionally, it’s crucial to avoid aggressive driving behavior, such as weaving in and out of lanes, as this can increase the risk of accidents in congested conditions. Always keep an eye on the surrounding traffic and maintain your focus to ensure safety.
