Section 9: Rules of the Road

Speed

In Utah, the basic speed law states that you may never drive faster than is reasonably safe. However, when there is no sign and where no special hazards exist, the following speeds are permitted:
speed limit 20
  • When passing a school building or grounds during school recess.
  • While children are going to or leaving school during opening or closing hours or when flashing lights are operating.
speed limit 25
  • In any business or residential area.
speed limit 55
  • On major highways, as posted.
speed limit 65, 70, 75, 80
  • On rural interstate highways.
  • The transition zones in Utah are indicated with pavement markings and additional signs.

In addition to the above speed limits, there are times when the law requires that you slow down.

SOME OF THOSE TIMES INCLUDE:
  • When approaching and crossing an intersection or railroad crossing.
  • When approaching and going around a curve.
  • When approaching the top of a hill.
  • When traveling on any narrow or winding road.
  • When special hazards such as people walking beside the road, heavy traffic, or dangerous road conditions exist.
  • During poor weather conditions. Driving on an icy road at 10 miles per hour or on an open highway on a rainy night at 25 miles per hour may be too fast.
  • Any time when you cannot see clearly.
  • In any highway work zone construction, maintenance, or utility work is done.
  • When approaching any authorized vehicle flashing red, red and white, or red and blue lights.
  • When speed causes the person to fail to maintain control of the vehicle or stay within a single lane of travel.

On the other hand, do not drive so slowly that you become a source of danger on the road. Peace officers are allowed to issue you a citation if you are impeding the normal flow of traffic.
