Which type of vehicle is most likely to be traveling slowly on the road?

Farm equipment is most likely to be traveling slowly on the road due to its design and purpose. Equipment such as tractors and combines are built for agricultural tasks, which often require low-speed operations, especially when working in fields or transporting goods within rural areas. The speed of farm machinery on public roads is typically much lower than that of other vehicles, and this is a significant safety consideration for both operators and drivers of faster vehicles.

While delivery trucks, bicycles, and motorcycles can also be slower than regular passenger vehicles, they generally do not have the same consistent limitations on speed as farm equipment. Delivery trucks, depending on their load and road conditions, can travel at normal traffic speeds. Bicycles, while they can be slower, are designed for mobility and often share road space with faster-moving traffic. Motorcycles usually travel at similar speeds to cars and can accelerate quickly, making it less likely for them to be categorized with slower vehicles compared to farm equipment.
