The infraction or offense of speeding in a school zone is committed when the driver of a motor vehicle in a marked school zone exceeds the posted speed limit or exceeds the speed limit that is reasonable and prudent under the circumstances or conditions—conditions such as the road (straight, curved, wet, dry, icy, flat, hilly); the weather (clear, foggy, raining, snowing); the visibility; and the presence of children in a crosswalk, for example.

Laws regarding speeding in a school zone vary from state to state and among cities and towns and are usually located in a state’s statutes and sometimes in local ordinances enacted by cities or towns.

The penalty for speeding in a school zone is usually a fine and demerit points added to the driver’s license or driving record. But the fines and penalties for speeding in a school zone are usually much greater than for a typical speeding ticket or citation.

In Nevada, speeding in a school zone is considered a more serious offense than regular speeding due to the increased risk to children. The specific regulations and penalties are outlined in Nevada Revised Statutes (NRS) 484B.363 and local ordinances. The law stipulates reduced speed limits in school zones when children are present, typically during school hours or when a school crossing sign is flashing. Fines for speeding in a school zone in Nevada are generally higher than for standard speeding violations and can also include demerit points on the driver's license. The exact amount of the fine and the number of demerit points can vary depending on the jurisdiction within the state and the speed at which the driver was traveling over the posted limit. Additionally, repeat offenses may lead to increased penalties, and in some cases, community service or traffic school may be required.
