Nevada Bans Lane Splitting and Filtering by Motorcycles

Nevada answers this question with an express prohibition rather than by silence, which matters because it removes any argument that lane splitting is merely unaddressed. NRS 486.351(1) reaches the space between lanes and forbids a motorcycle or moped from being driven between vehicles occupying adjacent traffic lanes. The words "moving or stationary" are doing real work: filtering between cars stopped at a Las Vegas signal is prohibited on exactly the same terms as splitting at speed on US 95, so a rider gains nothing by waiting for traffic to halt first. The only carve-out is a police officer in the performance of his or her duty, and it applies to that subsection alone.

Subsection 2 covers the other half of the problem, the space inside a lane. No person may drive a motorcycle, moped or trimobile abreast of, or overtake or pass, another vehicle within the same traffic lane. That is why a rider cannot squeeze past a car by hugging the lane line while technically staying between the markings. Note who is listed: subsection 2 names trimobiles alongside motorcycles and mopeds, while subsection 1 names only motorcycles and mopeds. Nevada also grants one deliberate exception in subsection 3, and it is narrow. Motorcycles and mopeds may be operated no more than two abreast in a single traffic lane, and only with the consent of the drivers, so two riders may share a lane with each other but never with a car and never three across. Trimobiles are absent from that allowance.

The prohibition sits next to a right that runs the other way. NRS 486.341 entitles every motorcycle or moped being driven on a highway to the full use of the traffic lane it is occupying, and forbids the driver of another motor vehicle from driving in a manner that would deprive the motorcycle of that use. Nevada therefore refuses to treat a lane as shareable in either direction: a car may not crowd a rider out of a lane, and a rider may not slip between lanes. NRS 486.331 completes the frame by giving motorcycle and moped riders all the rights and duties of other drivers "except as otherwise provided in NRS 486.351," naming the splitting ban as the specific departure.

The shoulder is not an alternative route. NRS 484B.210 permits overtaking on the right only in the listed situations, such as when the vehicle ahead is signaling a left turn or where the pavement is wide enough for two lines of moving vehicles in each direction, and subsection 3 flatly bars passing on the right where the movement requires driving off the paved portion of the highway. Where signs do allow shoulder running, subsection 4 names the vehicles that qualify: authorized emergency vehicles, vehicles permitted to operate as such under NRS 484A.490, traffic incident management vehicles, tow cars, coroner vehicles and public transit motor buses. Motorcycles are not on that list.

Mopeds carry an additional lane-position duty that motorcycles do not. Under NRS 486.351(4) a moped rider on a highway with two or more marked lanes running in the rider’s direction must stay in the extreme right-hand lane, unless preparing to turn left, unless doing so would not be safe, or unless following a police officer’s directions. Subsection 5 lets a moped rider preparing to turn left enter the turning lane, but not more than one-quarter of a mile before the turn is made.

Since Nevada’s decriminalization of most traffic offenses took effect, this is no longer a criminal matter. NRS 486.381 provides that any person violating NRS 486.011 to 486.361, inclusive, is guilty of a civil infraction unless one of those sections specifically declares the violation a misdemeanor, gross misdemeanor or felony. NRS 486.351 declares nothing of the kind, so lane splitting is a civil infraction. NRS 484A.7043 sets the exposure at a civil penalty of not more than $500 per violation unless a greater penalty is authorized by a specific statute, plus the administrative assessments that would apply if the penalty were a misdemeanor fine under NRS 176.059, 176.0611, 176.0613 and 176.0623. The citation itself must carry a statement that a civil infraction is not a criminal offense, under NRS 484A.7035(1)(b).

A rider who ignores the citation is not simply left alone. NRS 484A.7047 adds a collection fee of up to $100 where the delinquency is under $2,000, up to $500 where it is between $2,000 and $5,000, and 10 percent of the amount above that, and the city or county may contract with a licensed collection agency to pursue it. Cities and counties cannot make the underlying conduct worse: NRS 486.385 bars a local authority from enacting an ordinance that imposes a criminal penalty for a violation of chapter 486 for which the chapter prescribes a civil penalty, so a Las Vegas, Henderson or Reno ordinance cannot turn lane splitting back into a misdemeanor. Where splitting is done aggressively, the conduct can also feed a separate charge such as reckless driving under chapter 484B, which is punished on its own terms rather than as a civil infraction, and a crash caused by riding between lanes leaves the rider carrying the fault in any civil claim.
