What speed must slow-moving vehicles be designed to operate at or below?

Slow-moving vehicles are typically designed to operate safely at speeds that are significantly lower than the normal traffic flow on most roadways. In Texas, legislation states that a slow-moving vehicle is defined as one that cannot maintain a speed greater than 25 miles per hour. This speed limit ensures that the vehicles can operate without posing a danger to themselves or other motorists on the road, as they are equipped with appropriate warning devices, such as a slow-moving vehicle emblem. Therefore, the specification that slow-moving vehicles should be designed to operate at or below 25 mph aligns perfectly with safety regulations and promotes safe interactions between slower and faster vehicles on the road.
