SPEED RESTRICTIONS 39-09-01. Basic rule - Penalty for violation. No person may drive a vehicle at a speed greater than is reasonable and prudent under the conditions and having regard to the actual and potential hazards then existing. Consistent with the foregoing, every person shall drive at a safe and appropriate speed when approaching and crossing an intersection or railroad grade crossing, when approaching and going around a curve, when approaching a hill crest, when traveling upon any narrow or winding roadway, and when special hazards exist with respect to pedestrians or other traffic or by reason of weather or highway conditions. Any person who drives a vehicle upon a highway or private or public property open to the public for the operation of motor vehicles without heed to the requirements or restrictions of this section has committed careless driving and must be assessed a fee of thirty dollars. Any person who, by reason of careless driving as herein defined, causes and inflicts injury upon the person of an operator of snow removal equipment engaged in snow removal operations or causes damage in excess of one thousand dollars to snow removal equipment engaged in snow removal is guilty of an infraction. As used in this section, "snow removal equipment" means a vehicle that is operated by a person employed by or on behalf of an authority in charge of the maintenance of the highway to perform winter maintenance snow and ice removal, including plowing, hauling away, salting, and sanding. 39-09-01.1. Care required in operating vehicle.

No person may drive any vehicle upon a highway in a manner to endanger the life, limb, or property of any person. 39-09-02. Speed limitations. 1. Subject to the provisions of section 39-09-01 and except in those instances when a lower speed is specified in this chapter, it presumably is lawful for the driver of a vehicle to drive the same at a speed not exceeding: a. Twenty miles [32.19 kilometers] an hour when approaching within fifty feet [15.24 meters] of a grade crossing of any steam, electric, or street railway when the driver's view is obstructed. A driver's view is deemed to be obstructed when at any time during the last two hundred feet [60.96 meters] of the driver's approach to such crossing, the driver does not have a clear and uninterrupted view of such railway crossing and of any traffic on such railway for a distance of four hundred feet [121.92 meters] in each direction from such crossing. b. Twenty miles [32.19 kilometers] an hour when passing a school during school recess or while children are going to or leaving school during opening or closing hours, unless a lower speed is designated or posted by local authorities. c. Twenty miles [32.19 kilometers] an hour when approaching within fifty feet [15.24 meters] and in traversing an intersection of highways when the driver's view is obstructed. A driver's view is deemed to be obstructed when at any time during the last fifty feet [15.24 meters] of the driver's approach to such intersection, the driver does not have a clear and uninterrupted view of such intersection and of the traffic upon all of the highways entering such intersection for a distance of two hundred feet [60.96 meters] from such intersection. d. Twenty miles [32.19 kilometers] an hour when the driver's view of the highway ahead is obstructed within a distance of one hundred feet [30.48 meters].

Twenty-five miles [40.23 kilometers] an hour on any highway in a business district or in a residence district or in a public park, unless a different speed is designated and posted by local authorities. f. Fifty-five miles [88.51 kilometers] an hour on gravel, dirt, or loose surface highways, and on paved two-lane county and township highways if there is no speed limit posted, unless otherwise permitted, restricted, or required by conditions. g. Sixty-five miles [104.61 kilometers] an hour on paved two-lane highways if posted for that speed, unless otherwise permitted, restricted, or required by conditions. h. Seventy miles [112.65 kilometers] an hour on paved and divided multilane highways, unless otherwise permitted, restricted, or required by conditions. i. Seventy-five miles [120.70 kilometers] an hour on access-controlled, paved and divided, multilane interstate highways, unless otherwise permitted, restricted, or required by conditions. The director may designate and post special areas of state highways where lower speed limits apply. Differing limits may be established for different times of the day within highway construction zones which are effective when posted upon appropriate fixed or variable speed limit signs. Except as provided by law, it is unlawful for any person to drive a vehicle upon a highway at a speed that is unsafe or at a speed exceeding the speed limit prescribed by law or established pursuant to law. In charging a violation of the provisions of this section, the complaint must specify the speed at which the defendant is alleged to have driven and the speed which this section prescribes is prima facie lawful at the time and place of the alleged offense.
39-09-03. When local authorities may or shall alter maximum speed - Limits - Signs posted. 1. Whenever local authorities in their respective jurisdictions, on the basis of an engineering and traffic investigation, determine that the maximum speed permitted under this title is greater or less than is reasonable and safe under the conditions found to exist upon a highway or part of a highway, the local authority may determine and declare a reasonable and safe maximum limit thereon which: a. Decreases the limit at intersections; b. Increases the limit within an urban district but not to more than fifty-five miles [88.51 kilometers] per hour; or c. Decreases the limit outside an urban district. 2. Local authorities in their respective jurisdictions shall determine by an engineering and traffic investigation the proper maximum speed for arterial streets and shall declare a reasonable and safe maximum limit thereon which may be greater or less than the maximum speed permitted under this chapter for an urban district. 3. Any altered limit established as hereinabove authorized shall be effective at all times or during hours of darkness or at other times as may be determined when appropriate signs giving notice thereof are erected upon such street or highway. 4. Any alteration of maximum limits on state highways or extensions thereof in a municipality by local authorities may not be effective until such alteration has been approved by the director. 5. Not more than six such alterations as hereinabove authorized may be made per mile [1.61 kilometers] along a street or highway, except in the case of reduced limits at intersections, and the difference between adjacent limits may not be more than ten miles [16.09 kilometers] per hour. 39-09-04. Alteration of maximum speed limits on state highways. The maximum speed limits specified in section 39-09-02 may be altered on all or any part of the state highway system by an administrative order by the director after a public hearing has been held. Such determination must be based on engineering and traffic investigations with primary consideration given to the establishment of reasonable and safe speeds, highway

conditions, enforcement, and the general welfare. Speed limits established pursuant to this section shall be effective only when appropriate signs giving notice thereof are erected and such maximum speed limits may be declared to be effective at all times or at such times as are indicated upon said signs. Differing limits may be established for different times of the day, different types of vehicles, varying weather conditions, and other factors bearing on safe speeds, which shall be effective when posted upon appropriate fixed or variable signs. 39-09-04.1. Special speed limitations. 1. No person may drive any vehicle equipped with solid rubber tires at a speed greater than a maximum of ten miles [16.09 kilometers] per hour. 2.

The director or other authority having jurisdiction may conduct an investigation of any public bridge, causeway, or viaduct and if the director finds that such structure cannot safely withstand the traveling of vehicles at the speed otherwise permissible under this chapter, such director or other authority shall determine and declare the maximum speed of vehicles such structure can withstand. The director or other authority shall cause or permit signs to be erected and maintained at a distance of one hundred feet [30.48 meters] from each end of such structure. Such signs must state the maximum speed permissible over such structure. The findings and determination of the director or other authority are conclusive evidence of the maximum speed which can be maintained without hazard to any such structure. 39-09-05. Driving vehicle upon bridge, causeway, or viaduct at greater than maximum speed prohibited. Repealed by S.L. 1975, ch. 348, § 17. 39-09-06.
