Nebraska Studded Tires: Legal Only November 1 to April 1

The Nebraska rule is drafted as a prohibition with exceptions, which is why the season matters so much. Section 60-6,250(2) says no tire on a vehicle moved on a highway shall have on its periphery any stud, flange, cleat or spike, or any other protuberance of a material other than rubber that projects beyond the tread of the traction surface. Studs are legal only because subdivision (2)(a) suspends that prohibition for a defined winter period. Outside November 1 through April 1 there is no permission left standing, so a set of studded snow tires that is perfectly lawful on March 31 is an equipment violation on April 2. The offence attaches to moving the vehicle on a highway, so studded tires stored in a garage or mounted on a trailer parked off the road are not what the section reaches.

Two dimensions control whether a stud qualifies at all. The stud may not exceed five-sixteenths of an inch in diameter, and the statute specifies that the measurement is taken "inclusive of the stud-casing," so the metal jacket counts toward the limit rather than being measured separately. The second figure is an average, not a ceiling on any single stud: the tire must show "an average protrusion beyond the tread surface of not more than seven sixty-fourths of an inch." A worn set whose remaining studs sit proud after the tread has gone down can fail that average even though it passed when new, which is the practical reason to check protrusion at the end of a Nebraska winter and not only at the start.

Three categories of vehicle are exempt from the calendar entirely. Subdivision (2)(a) closes with the words "except that school buses, mail carrier vehicles, and emergency vehicles shall be permitted to use metal or metal-type studs at any time during the year." The exemption is written by vehicle type, not by the driver, the errand or the county, so a rural mail carrier vehicle keeps its studs through a Nebraska July while the ordinary commuter behind it does not.

Chains are handled separately and on a different logic. Subdivision (2)(c) makes it "permissible to use tire chains of reasonable proportions upon any vehicle when required for safety because of snow, ice, or other condition tending to cause a vehicle to slide or skid." There is no date range on that allowance and no size table, only the twin tests of reasonable proportions and actual need. Nebraska does not pair this with any chain-control power in the same section: the only administrative authority § 60-6,250 grants is in subsection (4), where the Department of Transportation and local authorities may issue special permits for traction engines or tractors with movable tracks carrying transverse corrugations, and for farm tractors and other farm machinery.

The rest of the section fills in what may touch a Nebraska road. Subsection (3) bars operating any motor vehicle, trailer or semitrailer with a metal tire in contact with the roadway or with solid rubber tires, and exempts farm vehicles with a gross weight of ten thousand pounds or less and implements of husbandry. Subsection (1) requires any solid rubber tire that is on the road to carry at least one inch of rubber above the flange edge over the entire periphery. Subdivision (2)(b) allows farm machinery with protuberances "which will not injure the highway," a damage test rather than a dimensional one. The neighbouring section, § 60-6,249, requires pneumatic tires on all vehicles including trailers except those operated at twenty miles per hour or less, and § 60-6,252(2)(c) sets the separate tread-depth floor at two thirty-seconds of an inch measured in any two tread grooves at three locations equally spaced around the circumference.

No Nebraska city or county can lengthen the stud season. Section 60-6,108(3) provides that the Nebraska Rules of the Road are applicable and uniform throughout the state and in all political subdivisions and municipalities, and that no local authority shall enact or enforce any ordinance directly contrary to them unless expressly authorized by the Legislature. The stud window is therefore the same in Omaha, in Scottsbluff and on a county road in the Sandhills, and a local snow emergency changes plowing and parking rules rather than tire equipment rules.

Section 60-6,250 sits inside the Nebraska Rules of the Road, so under § 60-682 a violation for which no other penalty is declared is a traffic infraction rather than a misdemeanor. Section 60-689 sets the fine for a traffic infraction with no specific penalty at not more than one hundred dollars for a first offense, not more than two hundred dollars for a second within a one-year period, and not more than three hundred dollars for a third or subsequent offense within a one-year period.

Under the point system in § 60-4,182, subdivision (17) assigns one point to all other reportable traffic violations, and the list of items excluded from that catch-all covers occupant protection systems, parking, driving without the license in possession, mufflers, overwidth or overheight or overlength loads, helmets and overloaded trucks. Tire equipment is not on that exclusion list, so a stud violation is a one-point offense. Enforcement is roadside: § 60-683 makes enforcing the Rules of the Road part of every peace officer's official duty and authorizes arrest upon view without warrant for a violation committed in the officer's presence, and § 60-683(4) lets a uniformed officer require the driver to present the vehicle within five days for correction of defects the officer reasonably believes make the vehicle unlawful, which is the usual disposition for late studs.
