A person may not operate a vehicle at a speed greater than is reasonable and prudent under the existing conditions, giving regard to the actual and potential hazards then existing, including when: approaching and crossing an intersection or railroad grade crossing; approaching and going around a curve; approaching a hill crest; traveling upon any narrow or winding roadway; traveling in, through, or approaching other hazards that exist due to pedestrians, other traffic, weather, or highway conditions; and the speed causes the person to fail to maintain control of the vehicle or stay within a single lane of travel. Subject to Subsections (1) and (4) and Sections 41-6a-602 and 41-6a-603, the following speeds are lawful: 20 miles per hour in a reduced speed school zone as defined in Section 41-6a-303; 25 miles per hour in any urban district; and 55 miles per hour in other locations. Except as provided in Section 41-6a-604, any speed in excess of the limits provided in this section or established under Sections 41-6a-602 and 41-6a-603 is prima facie evidence that the speed is not reasonable or prudent and that it is unlawful. A violation of Subsection (1) is an infraction. For an individual convicted of a speed violation where the individual was operating at a speed of 100 miles per hour or more, the court shall impose a fine not less than 150% of the suggested fine in the uniform fine schedule authorized in Section 76-3-301.5 and in effect at the time of the citation. The governor by proclamation in time of war or emergency may change the speed limits on the highways of the state.
