Overcoming the Helmet Defense in North Dakota Motorcycle Injury Cases

Cruising bareheaded along Interstate 94 near Bismarck or down US Highway 83 is a completely legal personal choice for adult motorcyclists in North Dakota. Yet the moment a distracted motorist turns left across your lane or rear-ends your bike at a stoplight, insurance defense lawyers immediately attempt to turn that lawful choice into a weapon against your financial recovery. Even when the other driver was 100% responsible for causing the collision, adjusters routinely raise the "helmet defense" to argue that you failed to mitigate your own injuries.

Left unchallenged, this defense tactic can strip tens or hundreds of thousands of dollars from a settlement under North Dakota's modified comparative fault system. Overcoming the helmet defense in North Dakota motorcycle injury cases requires a precise mastery of state traffic statutes, biomechanical engineering evidence, and the strict evidentiary boundaries established by the North Dakota Supreme Court, Bismarck.

Minor vs. Adult Helmet Rules

Since repealing its universal adult helmet mandate in 1977, North Dakota has maintained an age-specific headgear statute codified at N.D. Cent. Code § 39-10.2-06. Understanding the exact statutory text is essential, because the law contains a little-known passenger rule that frequently catches adult riders off guard during insurance investigations:

• Riders and Passengers Under Age 18: Under N.D. Cent. Code § 39-10.2-06(1), no person under eighteen years of age may operate or ride upon a motorcycle unless wearing a safety helmet that meets U.S. Department of Transportation (DOT) standards, except when participating in a lawful parade.
• Adult Operators Carrying Minor Passengers: Under N.D. Cent. Code § 39-10.2-06(3), an adult operator is prohibited from operating a motorcycle if a passenger under age 18 is on the bike without a compliant safety helmet.
• The Adult Passenger Trap: Under N.D. Cent. Code § 39-10.2-06(1), if the operator of the motorcycle is required to wear a safety helmet (meaning the operator is under age 18), any passenger must also wear a safety helmet regardless of the passenger's age. Thus, a 45-year-old parent riding on the back of a 17-year-old's motorcycle is legally required to wear a helmet.
• Statutory Exemptions: Under N.D. Cent. Code § 39-10.2-06(2), the helmet requirement does not apply to individuals riding within an enclosed cab or on a golf cart.

Traumatic Brain Injury Valuations Without a Helmet

When an unhelmeted adult motorcyclist suffers a concussion, skull fracture, or severe Traumatic Brain Injury (TBI), insurance adjusters immediately cite North Dakota's modified comparative fault statute, N.D. Cent. Code § 32-03.2-02. That statute includes "failure to exercise reasonable care to avoid an injury or to mitigate damages" within the definition of fault under N.D. Cent. Code § 32-03.2-01, and bars recovery altogether if a plaintiff's contributing fault is 50% or greater.

However, insurers rarely tell injured riders about the strict legal protections established in the landmark case Halvorson v. Voeller, 336 N.W.2d 118 (ND Supreme Court 1983). In that decision, the North Dakota Supreme Court, Bismarck ruled that unless the failure to wear a helmet actually caused the accident itself (which the court noted is virtually inconceivable), helmet nonuse is irrelevant to liability and applies solely to the mitigation of damages. Furthermore, a jury cannot speculate about whether a helmet would have helped. Under Halvorson v. Voeller, 336 N.W.2d 118 (ND Supreme Court 1983), the defendant bears the burden of proving two distinct elements through competent expert testimony:

1. That a reasonably prudent person would have worn a safety helmet under the specific circumstances; and
2. That the motorcyclist would not have sustained some or all of the specific head injuries had a helmet been worn.

Experienced North Dakota trial attorneys defeat or minimize TBI reductions by retaining biomechanical engineers and neurosurgeons to expose flaws in the defense expert's math. Standard motorcycle helmets governed by federal standard 49 C.F.R. § 571.218 (FMVSS 218) are tested primarily for linear impact attenuation at approximately 13 to 15 mph. They often cannot prevent severe rotational acceleration forces that cause diffuse axonal injury (DAI) or high-speed coup-contrecoup brain trauma when a biker is struck at highway speeds of 55 to 75 mph. Additionally, if you suffered $400,000 in orthopedic fractures, spinal cord damage, or internal organ trauma alongside a concussion, the defense is legally barred from applying a helmet reduction to your orthopedic and bodily damages.

Fighting Facial Disfigurement Bias

A secondary battleground involves riders who suffer broken jaws, lost teeth, orbital fractures, or severe facial lacerations-either while riding without a helmet or while wearing a legal "half-helmet" or open-face three-quarter helmet. Defense attorneys frequently attempt to blame the rider for not wearing a full-face helmet with a chin bar.

Your legal team can neutralize this bias before a jury ever hears it. First, under 49 C.F.R. § 571.218 and N.D. Cent. Code § 39-10.2-06, DOT-certified half-helmets and three-quarter helmets fully satisfy federal and state safety standards; there is zero legal duty anywhere in the United States to wear a full-face racing helmet. Second, if the defense cannot produce a qualified biomechanical reconstructive expert who can prove with scientific certainty how a standard helmet would have prevented a specific maxillofacial injury, your attorney can file a formal Motion in Limine under N.D. R. Evid. 403 to exclude all mention of helmet usage at trial on the grounds that its unfair prejudice substantially outweighs any probative value.

Step-by-Step Process in North Dakota

If an insurance adjuster in Fargo, Bismarck, Grand Forks, or Minot is blaming you for not wearing a helmet, taking these structured steps protects the value of your injury claim.

Step 1: Refuse Recorded Statements About Your Riding Gear

Insurance adjusters are trained to ask leading questions such as, "Do you own a helmet, and why did you leave it in the garage that day?" to manufacture evidence of unreasonable conduct under the first prong of Halvorson v. Voeller, 336 N.W.2d 118 (ND Supreme Court 1983). Decline recorded interviews and refer the adjuster to your attorney.

Step 2: Preserve Your Riding Gear and Obtain the Crash Report

If you were wearing a half-helmet, shatterproof eyewear, or protective riding jacket, place those items in sealed storage immediately and photograph every scuff mark. Request the official police crash report from the North Dakota Department of Transportation, Bismarck using Form SFN 4901, North Dakota, Department of Transportation, Request for Crash Report Information to verify how the officer coded safety equipment and crash fault.

Step 3: Segregate Head Trauma from Orthopedic and Spinal Damages

Work with your treating physicians and billing specialists to clearly separate diagnostic and surgical bills for neck, back, chest, and limb injuries from cranial treatment. Because a helmet only covers the skull, 100% of your non-head medical expenses and related pain and suffering must be insulated from any helmet mitigation argument.

Step 4: Retain a Biomechanical and Neurosurgical Expert

If the defense hires an engineer to claim a helmet would have prevented your TBI, your lawyer will counter with biomechanical modeling of impact speed, rotational G-forces, and angle of ejection to demonstrate that the trauma exceeded standard DOT helmet thresholds.

Step 5: File a Motion in Limine in North Dakota District Court

When filing suit in the Cass County District Court, Fargo, the Burleigh County District Court, Bismarck, the Grand Forks County District Court, Grand Forks, or the Ward County District Court, Minot, your attorney will petition the judge before trial under N.D. R. Evid. 403 and N.D. R. Evid. 702 to bar speculative helmet arguments from reaching the jury.

How Much Does it Cost in North Dakota?

Overcoming a contested helmet defense requires specialized litigation resources, nearly all of which are advanced by your injury law firm:

• District Court Civil Filing Fees: Filing a civil complaint in a North Dakota District Court costs $160.00 under N.D. Cent. Code § 27-05.2-03(1)(a), while the defense pays a $100.00 answer fee under N.D. Cent. Code § 27-05.2-03(1)(c).
• Biomechanical and Medical Expert Fees: Hiring a credentialed biomechanical engineer, accident reconstructionist, or neuropsychologist to rebut the helmet defense typically costs between $5,000 and $15,000. Reputable personal injury firms advance these litigation costs upfront and only recover them if they win or settle your case.
• Crash Records and Service Costs: Retrieving the crash report via Form SFN 4901, North Dakota, Department of Transportation, Request for Crash Report Information costs $2.00 to $7.00, and sheriff service of process costs $40.00 to $85.00.
• Attorney Contingency Fees: North Dakota motorcycle lawyers represent injured bikers on a no-win, no-fee contingency basis, typically receiving 33.3% of pre-suit settlements or 40% if the case requires formal District Court litigation.

How Long Does the Process Take?

Cases involving the helmet defense and head trauma take longer to resolve than simple fender-benders because neurological recovery cannot be rushed:

• Neurological Stabilization and MMI (6 to 18 Months): Brain injuries evolve over time. Neurologists and neuropsychologists generally require 6 to 18 months of post-crash observation before issuing a final permanency rating and life-care plan.
• Expert Discovery and Daubert Motions (6 to 12 Months): Once a lawsuit is commenced in District Court, both sides exchange expert witness disclosures, conduct depositions of the biomechanical engineers, and argue pre-trial Motions in Limine.
• Overall Case Resolution (12 to 24 Months): While North Dakota allows up to 6 years to file a personal injury lawsuit under N.D. Cent. Code § 28-01-16(5), most contested helmet-defense cases settle at mediation or reach a jury verdict within 12 to 24 months of filing.
