State Highway Naming
The approved format for State Highway naming in Utah is: SR-##
In Utah we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
|Highest rank of connected segments|
Utah follows the Waze USA speed limits guidance. Please read that page carefully before editing any Speed Limits (SLs).
Utah does not alter speed limits for work zones, or other temporary reductions in speed limit.
