§ 28-644. Obedience to and required traffic control devices
A. Unless otherwise directed by a traffic or police officer and subject to the exemptions granted the driver of an authorized emergency vehicle in this chapter, the driver of a vehicle shall:
1. Obey the instructions of an official traffic control device applicable to the driver that is placed in accordance with this chapter.
2. Not drive over or across or park in any part of a gore area. This paragraph does not apply to the driver of a vehicle that is disabled while on the paved or main traveled portion of a highway in a manner and to an extent that it is impossible to avoid stopping and temporarily leaving the disabled vehicle in that position. For the purposes of this paragraph, "gore area" means the area that is between a through roadway and an entrance ramp or exit ramp and that is defined by two wide solid white lines that guide traffic entering or exiting a roadway. Gore area does not include a safety zone.
B. Any provision of this chapter that requires signs shall not be enforced against an alleged violator if at the time and place of the alleged violation an official sign is not in proper position and sufficiently legible to be seen by an ordinarily observant person. If a particular section of law does not state that signs are required, that section is effective even though no signs are erected or in place.
