Which vehicles can cause serious accidents when this traffic sign is ignored?

The sign indicates a height restriction of 3.8 meters. Vehicles exceeding this height may pose risks, particularly in underpasses, bridges, or areas with low overhead obstacles. Ignoring this sign can lead to serious accidents or collisions.

Heavy and tall vehicles, such as buses and trucks, are more likely to be involved in such incidents if they attempt to pass under a structure with this restriction. It's crucial for drivers of larger vehicles to adhere to height regulations to ensure safety on the road. In Germany, traffic regulations clearly define these limitations to prevent accidents and maintain traffic flow.
