At what distance should a warning triangle be placed if a vehicle breaks down on any road except the autobahn?

A warning triangle should be placed at a distance of 100 meters (approximately 300 feet) from a broken-down vehicle on roads outside of the autobahn. This distance is critical for safety as it provides adequate warning to other drivers about the hazard ahead, allowing them to slow down and navigate safely around the obstacle.

The 100-meter distance is a widely accepted standard, aligning with safety guidelines designed to prevent accidents and ensure the visibility of the warning triangle from a sufficient distance. It ensures that approaching vehicles have enough time to react, especially on roads where speeds may still be significant, even if they are not as high as those on the autobahn.

Other distances, while they may also seem reasonable, are not mandated as the appropriate safety measure in this context. For instance, shorter distances would not provide sufficient warning, while longer distances might be impractical in certain situations. Therefore, 100 meters strikes a balance between visibility and practical deployment in the event of a breakdown.
