Speeding
Utah Code 41-6a-601 — 25 in an urban district and 55 elsewhere unless posted
No one may drive faster than is reasonable and prudent for the existing conditions and hazards, including at intersections, curves, hill crests, narrow roads, and where pedestrians, traffic or weather call for it.
Who handles this in Utah: legal aid programs and the state offices, listed in the Utah directory.
| Where | Lawful speed unless set otherwise |
|---|---|
| WhereA reduced speed school zone | Lawful speed unless set otherwise20 miles per hour |
| WhereAny urban district | Lawful speed unless set otherwise25 miles per hour |

- Any speed over the limit is prima facie evidence that the speed is not reasonable or prudent and is unlawful.
- A violation is an infraction, and at 100 miles per hour or more the court imposes a fine of not less than 150% of the suggested fine in the uniform fine schedule.
