How many meters should Red Flag Lights be visible to other vehicles?

The correct answer is that Red Flag Lights should be visible to other vehicles from a distance of 50 meters. This distance is important for ensuring safety on the road, especially in situations where visibility may be reduced, such as during poor weather conditions or at night. By having the Red Flag Lights visible from 50 meters away, drivers have sufficient time to react and adjust their driving behavior in response to potential hazards, preventing accidents and ensuring smoother traffic flow.

In contexts where this type of visibility is specified, it allows other road users to identify vehicles that may be experiencing breakdowns or other issues requiring caution. This regulation emphasizes the importance of clear communication on the road, which is essential for maintaining safety for all types of vehicles.
