Final answer:
Tractors, animal-drawn vehicles, and roadway maintenance vehicles typically operate at 25 mph or less due to their specific functions that prioritize precision and safety over speed. Over time, older tractors can corrode if left exposed to the elements.
Step-by-step explanation:
Farm tractors, animal-drawn vehicles, and roadway maintenance vehicles usually go 25 mph or less. These types of vehicles are designed for specific tasks that do not require high speeds. Tractors, for instance, are used in agricultural settings where they perform a variety of tasks at low speeds to ensure precision and safety. Roadway maintenance vehicles also move slowly to ensure thorough and careful work is done on road repairs and maintenance. As technology has advanced, older tractors have often been abandoned in favor of newer models with better efficiency and functionality, leading the older models to be left to the elements and potentially corroding over time.
