Key NH Car Accident Statistics at a Glance
The latest New Hampshire Office of Highway Safety data shows how often crashes occur, where the most serious crashes happen, and which driving behaviors remain major safety concerns.
Important starts include:
- Total Crashes: New Hampshire recorded 30,782 crashes in 2024, the most recent year with a reported statewide total.
- Traffic Fatalities: The state recorded 139 traffic deaths in 2025, compared with 133 in 2024. The 2025 figure remains preliminary.

How Many Car Accidents Happen in New Hampshire Each Year?
New Hampshire recorded 30,782 motor vehicle crashes in 2024, the latest year for which the state’s current annual report provides a statewide total. That was an increase from 27,997 crashes in 2023.
The New Hampshire Office of Highway Safety’s 2025 Annual Report doesn’t yet provide a final statewide crash total for 2025. It states that overall crashes increased 8.3% from 2024 to 2025, but the underlying 2025 total was not final when the report was prepared.
These statewide numbers provide context, but the evidence from your individual collision still determines your injury claim. Your lawyer looks at what caused your crash, who was responsible, and how the collision affected you.
For more information about how different collision types affect fault, see Coates Law Office’s discussion of rear-end collisions and other common types of car accidents.
What Are the Most Common Causes of Car Accidents in New Hampshire?
Distracted driving, speeding, and impairment remain major factors in New Hampshire crashes, but the state does not publish five crash causes using one directly comparable percentage measure. The latest annual report instead tracks several crash and fatality factors separately.
The most useful current figures include:
- Fixed-Object Crashes: New Hampshire recorded 4,895 nonfatal fixed-object crashes in 2023, representing 17.5% of nonfatal crashes.
- Distracted Driving: Distracted driving contributed to 4,520 crashes in 2023, or 16.1% of crashes statewide.
- Speeding: Speed was involved in 51 of New Hampshire’s 133 traffic fatalities in 2024, or about 38%.
- Alcohol-Impaired Driving: Drivers with a blood alcohol concentration of 0.08 or higher were involved in 34 traffic fatalities in 2024, representing 26% of the state’s traffic deaths.
- Unrestrained Occupants: New Hampshire recorded 33 unrestrained passenger vehicle fatalities in 2025. Not wearing a seat belt doesn’t cause a crash, but it remains an important factor in the severity of injuries and fatalities.
Since these figures measure different things, they should not be treated as a single ranked list of crash causes. A lawyer instead uses the evidence from your collision to determine whether distraction, speeding, impairment, or another negligent act caused the accident.
Where and How Do Motor Vehicle Accidents Happen in New Hampshire?
Reviewing crash data shows that trouble spots aren’t limited to unfamiliar territory for those harmed. The latest New Hampshire crash analysis identifies Hillsborough, Rockingham, and Merrimack counties as having the highest average numbers of fatal crashes based on fatality and serious-injury data from 2020 through 2024.
In cities like Nashua, accident clusters occur at major intersections, busy downtown crossings, and areas with heavy traffic. These hotspots reveal that recurring issues like poor signage, congestion, or high pedestrian activity often set the stage for serious injuries.
Rear-end collisions and intersection wrecks pop up regularly in reporting from across New Hampshire. These scenarios often involve distracted driving, speeding, or running red lights. Recognizing these repeat patterns underscores that many victims share similar stories—your case is not just an isolated twist of fate.
Which New Hampshire Counties and Cities Have the Most Car Accidents?
Hillsborough, Rockingham, and Merrimack counties have the highest average numbers of fatal crashes in New Hampshire’s latest statewide risk analysis. Hillsborough County includes Nashua and Manchester, putting the state’s two largest cities within one of its highest-risk counties for serious crashes.
The New Hampshire Office of Highway Safety used fatal and serious-injury crash data from 2020 through 2024 to identify areas where enforcement and other safety resources should be concentrated.
The report identifies:
- Hillsborough County: Home to Nashua and Manchester, it ranked among the three counties with the highest average number of fatal crashes.
- Rockingham County: The state also identified Rockingham County among its highest-risk counties based on fatal and serious-injury crash data.
- Merrimack County: Merrimack County rounded out the three counties identified as having the highest average number of fatal crashes.
The current annual report doesn’t provide a comparable city-by-city table of total crashes, so it doesn’t support ranking Nashua, Manchester, or other cities by an exact current crash count.
For someone injured in Nashua, the statewide data still helps show why Hillsborough County receives focused highway-safety attention.
Understanding Comparative Fault and Common Crash Circumstances
New Hampshire uses a modified comparative fault rule, allowing compensation if you’re not more than 50% at fault for an accident. Statewide statistics identify several recurring crash and injury risk factors, including speeding, impairment, distraction, and lack of seat belt use.
If your crash involves one of these factors, the statewide data can provide broader context about that type of risk.
With a car accident lawyer on your side, you gain an advocate who understands how these recurring patterns connect to proving your side of the story under New Hampshire laws.
How Many Car Accident Fatalities Occur in New Hampshire?
New Hampshire recorded 139 traffic fatalities in 130 fatal crashes in 2025, according to the latest state annual report. The figure represents a 4.5% increase in fatalities from 2024, although some 2025 data remained preliminary because investigations and toxicology results were still pending.
The same report lists 133 traffic fatalities in 2024, 127 in 2023, 146 in 2022, and 104 in 2021. Those figures show that the number changes considerably from year to year rather than following a steady trend.
The National Highway Traffic Safety Administration’s Fatality Analysis Reporting System, or FARS, supplies the federal fatality data used in New Hampshire’s highway-safety reporting.
High-Risk Spots, Vulnerable Road Users, and Recurring Themes
Hotspots for serious accidents often line up with major intersections, state highways, rural routes, and crosswalks in bustling neighborhoods. New Hampshire also recorded 4,895 nonfatal fixed-object crashes in 2023, or 17.5% of nonfatal crashes reported in the state’s most recent detailed analysis of that crash type.
Motorcycle and pedestrian crashes also persist as a significant concern—visibility, sharing the road, and following the rules all play major roles. Motorcyclists accounted for 33 of New Hampshire’s 133 traffic deaths in 2024, or about 25%.
New Hampshire continues to record pedestrian fatalities each year. This concern highlights the need for safety improvements and the protection of individual rights after an incident.
What Percentage of NH Car Accidents Involve Drunk Driving?
New Hampshire’s current annual report does not publish a percentage showing how many of all statewide crashes involve drunk driving. It does report that alcohol-impaired driving accounted for 34 fatalities in 2024, or 26% of the state’s traffic fatalities that year.
For this federal measure, alcohol-impaired driving means a driver had a blood alcohol concentration of 0.08 or higher. The report lists 19 alcohol-impaired fatalities in 2025, representing 14% of traffic fatalities reported at that point, but it warns that the 2025 figure was not final because some cases still awaited toxicology results or investigation.
That distinction matters when using crash statistics. A percentage of fatalities involving alcohol is not the same as the percentage of all crashes involving alcohol. In an individual claim, police records, chemical test results, witness accounts, and other evidence help establish whether impairment contributed to the crash.
Alcohol, Distraction, and the Realities Behind the Numbers
The New Hampshire Office of Highway Safety’s 2025 Annual Report states that distracted driving contributed to 4,520 crashes in 2023, representing 16.1% of crashes statewide. Distracted driving, such as using cell phones, adjusting controls, or even interacting with passengers, remains a significant concern on New Hampshire roads.
Surviving an injury or losing a loved one to a crash involving drunk or distracted driving is far too common.
FAQ for New Hampshire Accident Statistics
These are the questions that come up most often when people connect statewide crash data to their own accident.
If I Had a Car Accident at a Common Hotspot, Would It Make My Claim Stronger?
Crash hotspots often reflect a history of design challenges or traffic flow issues. Accidents at these locations can provide helpful context, but still require facts relating to what actually happened to you.
What if My Accident Involved a Driver Who Was Speeding?
If the at-fault driver was speeding, it could strengthen your claim by demonstrating negligence. Speeding is a common factor in severe crashes, as it reduces reaction time and increases the force of impact. Evidence such as skid marks, black box data, or witness accounts helps prove a driver was speeding.
Are Rural Accidents Harder To Investigate?
Rural road accidents often occur in areas with limited lighting, fewer witnesses, and less surveillance, making it more challenging to gather evidence. However, these cases are still viable with the right legal approach.
A New Hampshire car accident lawyer can work to uncover details like road conditions, vehicle damage, and expert accident reconstruction to build a strong case.
Do New Hampshire Accident Statistics Matter in an Injury Claim?
Accident statistics can provide useful context about where and how serious crashes happen across New Hampshire. They can help explain broader risks, but the value of your claim still depends on your injuries, the available evidence, insurance coverage, and the facts of your specific accident.
Are Weather Conditions Common Factors in New Hampshire Crashes?
Snow, ice, rain, and poor visibility can all contribute to crashes in New Hampshire. Weather alone doesn’t decide fault, though. Drivers are still expected to adjust their speed and driving to the conditions.
