Unit 03 Lesson 01 - Understanding the Basic Speed Law

In Utah, there is the “Basic Speed Law” §41-6-46(1) which 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:
 
  • 20 miles per hour
    1. When passing a school building or grounds during school recess.
    2. While children are going to or leaving school during opening or closing hours or when flashing lights are operating.
  • 25 miles per hour – In any business or residential area.
  • 45 miles per hour – MINIMUM SPEED on a freeway under normal conditions.
  • 55 miles per hour – On major highways, as posted.
  • 65/75/80 miles per hour – On rural interstate highways. Because “rural” interstate is defined by census boundaries, it may be difficult to know which areas are 65 mph and which are 75, or 80 mph. “I thought this was a 75-mph zone” is not a valid response if you are pulled over. Remember, only when posted on interstate highways is 65, 75, or 80 mph allowed. The 65/75/80-mph 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:
  1. When approaching and crossing an intersection or railroad crossing.
  2. When approaching and going around a curve.
  3. When approaching the top of a hill.
  4. When traveling upon any narrow or winding road.
  5. When special hazards such as people walking beside the road, heavy traffic, or dangerous road conditions exist.
  6. During poor weather conditions. Driving on an icy road at 10 miles per hour or driving on an open highway on a rainy night at 25 miles per hour may be too fast.
  7. Any time when you cannot see clearly.
  8. In any highway work zones where construction, maintenance, or utility work is being done.
  9. When approaching any authorized vehicle which is flashing red, red and white, or red and blue lights. On the other hand, do not drive so slowly that you become a source of danger on the road. Traffic officers are allowed to issue tickets if you are interrupting the normal flow of traffic.
