Which of the following vehicles does NOT require a driver license in Utah?

In Utah, a road roller does not require a driver license because it is considered specialized equipment primarily used for construction and road maintenance. Such machinery is not typically driven on public roads in the same way that passenger cars, motorcycles, or all-terrain vehicles are. These other types of vehicles generally require a valid driver’s license, as they are designed for use on public highways and have specific rules and standards for operation.

Passenger cars and motorcycles require licenses because they are used for general transportation and must adhere to traffic laws, while all-terrain vehicles, which might also be used off-road, still have licensing requirements in various contexts, especially when operated on public streets. Understanding the specific regulations that apply to different types of vehicles helps ensure that drivers comply with state laws regarding their operation and safety.
