New Hampshire Car Accident Laws: A Complete Driver’s Guide
Navigating the aftermath of a car accident in New Hampshire requires knowledge of state-specific regulations on fault, insurance, reporting, and compensation. This guide breaks down key legal principles to help drivers, passengers, and victims understand their rights and responsibilities.
Immediate Steps After a Crash in New Hampshire
When involved in a vehicle collision, prioritize safety and compliance with state protocols. First, move to a safe location if possible and check for injuries. Call emergency services if anyone is hurt. Exchange information with other drivers, including names, contact details, vehicle details, and insurance info. Document the scene with photos of damage, road conditions, and skid marks.
New Hampshire mandates prompt reporting for serious incidents. Drivers must notify the Division of Motor Vehicles (DMV) in writing within 15 days if the crash results in injury, death, or property damage over $1,000. No separate report is needed if police investigate on-site.
- Ensure all parties are safe and seek medical attention.
- Notify police for official report, especially with injuries or disputes.
- Gather evidence: witness contacts, photos, and dashcam footage.
- File DMV report within 15 days for qualifying accidents (N.H. Rev. Stat. § 264:25).
Fault Determination: New Hampshire’s At-Fault System
New Hampshire operates as an at-fault state, meaning the driver responsible for causing the accident bears financial liability for damages. Insurance companies or courts investigate using police reports, witness statements, traffic camera footage, and expert reconstructions to assign fault.
Proving fault often hinges on negligence: a driver breached their duty of care, causing the crash and injuries. For instance, rear-end collisions typically presume the following driver at fault due to statutes prohibiting tailgating (N.H. motor vehicle laws).
| Fault Evidence Type | Description | Importance |
|---|---|---|
| Police Report | Official accident summary | Primary document for insurers |
| Witness Statements | Independent accounts | Corroborates events |
| Vehicle Damage | Pattern of impact | Indicates direction/speed |
| Expert Analysis | Accident reconstruction | Resolves complex cases |
Comparative Negligence: Sharing Blame in NH
New Hampshire applies a modified comparative negligence rule (N.H. Rev. Stat. § 507:7-d). Injured parties can recover damages if they are 50% or less at fault; compensation reduces proportionally to their fault percentage. If over 50% responsible, no recovery is allowed.
Example: In a $100,000 damage claim, if you’re 30% at fault, award drops to $70,000. This rule encourages careful driving while allowing partial recovery.
- 51% Bar Rule: Total bar on recovery if fault exceeds 50%.
- Encourages evidence gathering to minimize assigned fault.
- Courts apportion based on evidence, not assumptions.
Insurance Mandates and Financial Responsibility
Unlike many states, New Hampshire does not require drivers to carry auto insurance upfront but demands proof of financial responsibility post-accident. Drivers must cover damages via insurance, cash deposit, bond, or self-insurance certificate.
Minimum liability coverage, if insured, is 25/50/25: $25,000 per person/$50,000 per accident for bodily injury, $25,000 property damage. Insurers must offer uninsured motorist (UM) and medical payments (Med Pay) coverage.
| Coverage Type | Minimum Amount | Covers |
|---|---|---|
| Bodily Injury Liability | $25K/person, $50K/accident | Others’ medical, lost wages |
| Property Damage Liability | $25K | Others’ vehicle/property repairs |
| Uninsured Motorist BI | Matching liability | Your injuries from uninsured drivers |
| Med Pay | $1K minimum | Your medical bills regardless of fault |
Optional coverages include collision (own vehicle repairs), comprehensive (non-collision damage), towing, and rental reimbursement.
Deadlines for Filing Claims and Lawsuits
The statute of limitations for most car accident personal injury and property damage claims is three years from the accident date (N.H. Rev. Stat. § 508:4). Wrongful death claims start from the date of death, still within three years.
Minors have until age 20 to file. Missing deadlines bars lawsuits. Notify insurers promptly, even if under three years, as policies have shorter limits.
- Personal injury/property: 3 years from crash.
- Wrongful death: 3 years from death.
- Governmental claims: May have 180-day notice.
Types of Compensation Available
Victims seek economic damages (medical bills, lost wages, repairs) without caps, and non-economic (pain, suffering) up to $875,000 in some cases. Property damage has no cap.
Lawsuits arise if insurance limits are exceeded or liability disputed. Most settle out-of-court via negotiations.
- Economic: Quantifiable losses like bills and income.
- Non-Economic: Intangible harms, capped variably.
- Punitive: Rare, only for egregious conduct.
Special Scenarios: Pedestrians, Motorcycles, and More
Pedestrians, cyclists, and motorcyclists follow the same fault and comparative rules. Drivers must yield to them. Uninsured drivers complicate claims, relying on UM coverage.
Off-highway vehicles have separate liability under recreational statutes.
