What is the speed limit on major highways?

The speed limit on major highways in Utah is set at 55 mph for most vehicles. This regulation is designed to provide a balance between safety and efficiency on roadways that accommodate higher volumes of traffic and longer distance travel. By maintaining a speed limit of 55 mph, it helps reduce the likelihood of accidents, as higher speeds can result in more severe collisions and increased reaction times for drivers.

While some highway segments may have speed limits that are higher, particularly designed for certain types of vehicles or specific areas, the general standard for major highways is indeed 55 mph. This limit encourages drivers to maintain a safe distance from other vehicles, improves overall traffic flow, and reduces wear and tear on road infrastructure.

In this context, options reflecting lower speed limits, such as 45 mph, would be more appropriate for residential areas or certain city streets, whereas a limit of 65 mph or higher would not be the standard across most major highways, therefore making 55 mph the correct and commonly enforced limit in these areas.
