For optimal visibility, place the warning triangle:
50-150 meters behind your vehicle on highways.
20-50 meters behind in urban areas or low-speed roads.
On the side of the road (never in the lane).
Firmly on the ground to prevent it from being blown away.
This alerts other drivers in time to slow down and avoid accidents.
