Yes, studded tires are legal in North Dakota, but their use is tightly controlled under state and local traffic regulations. The North Dakota Department of Transportation (NDDOT) permits studded tires from October 15 to April 15 annually, aligning with seasonal road conditions. Municipalities like Fargo and Bismarck may impose additional restrictions during spring thaws to protect pavement integrity. Violations risk fines up to $100 under N.D. Cent. Code § 39-21-36, with enforcement prioritized in urban areas.
Key Regulations for Studded Tires in North Dakota
- Seasonal Window: Studded tires are lawful only from October 15 to April 15, as mandated by NDDOT. Outside this period, their use constitutes a traffic violation.
- Stud Specifications: Tires must comply with federal stud limits (≤ 1/16-inch protrusion) under 49 C.F.R. § 571.109. Non-compliant studs are prohibited year-round.
- Local Restrictions: Cities such as Fargo and Bismarck may impose temporary bans during spring melt periods to mitigate road damage. Check municipal ordinances for real-time updates.
