When operating a disabled vehicle on the Autostrada, how far should a warning triangle be placed behind it?

Answer: D — 200 meters

When operating a disabled vehicle on the Autostrada, a warning triangle should be placed 200 meters behind it. This distance is established to provide adequate warning to approaching vehicles, giving drivers ample time to react and maneuver safely around the obstruction. The Autostrada, being a high-speed roadway, requires motorist safety measures to be particularly vigilant. Positioning the warning triangle further away increases visibility for oncoming traffic, reducing the risk of accidents. The significant distance is crucial, as it allows drivers to notice the triangle and take necessary precautions well before reaching the disabled vehicle.
