Why is it advised to set up a warning triangle 200 meters behind a disabled vehicle on the Autostrada?

Setting up a warning triangle 200 meters behind a disabled vehicle on the Autostrada is crucial for notifying oncoming traffic of a hazard. This distance is recommended to ensure that drivers have ample time to notice the warning and safely react, thereby minimizing the risk of collisions. The Autostrada often has high-speed traffic, and visibility of a hazard is critical for preventing accidents. Placing the triangle at this specified distance gives drivers enough warning to slow down and maneuver appropriately in response to the disabled vehicle ahead.

Other options, while relevant in broader traffic context, do not specifically address the primary purpose of the warning triangle, which is to enhance safety by alerting drivers to potential dangers on the road.
