What is the function of the mobile barrier on the road?
Signage: Beacons and temporary signage
The main function of movable barriers is to temporarily prohibit passage to ensure safety during risk situations, such as train crossings or bridge movements.
Explanation
**Mobile barriers** on the road, such as those found at level crossings or movable bridges, serve the function of **temporarily prohibiting the passage** of vehicles. This occurs when the barriers are closed or in motion to open or close the passage. During this time, all vehicles must wait in their lane until the passage is clear. Once the barriers are raised and the passage is clear, vehicles can cross quickly. This measure is temporary and is used to ensure safety, preventing vehicles from crossing when there is a risk, such as the passage of a train or the movement of a bridge.
