If a large vehicle becomes disabled on a two-way highway, how far ahead should warning devices be placed?

When a large vehicle becomes disabled on a two-way highway, it is essential to place warning devices at a distance that provides ample warning to other drivers. The correct distance is 3 meters in front of the disabled vehicle. This spacing is designed to alert oncoming drivers in a timely manner, allowing them to react appropriately and avoid a potential collision with the disabled vehicle.

The choice of 3 meters is considered effective because it strikes a balance between being close enough to the vehicle to indicate danger while still being far enough away to give approaching drivers adequate time to observe and respond to the situation. Ensuring the warning devices are visible from a distance helps reduce the risk of accidents and enhances safety for both the vehicle occupants and other road users.
