How many caution triangles are required on trucks for emergency situations?

In emergency situations, trucks are required to carry three caution triangles. These triangles serve as essential safety equipment that helps alert other drivers of the truck's presence, especially if the vehicle is disabled on the road. The three triangles provide a clear warning to approaching traffic from multiple directions, significantly enhancing visibility and helping to prevent accidents or further incidents. Their proper placement can be critical in ensuring that other vehicles maintain a safe distance while the truck is stationary. This regulation underscores the importance of maintaining safety measures on the road, particularly for larger vehicles that may be harder to see.
