Motorcyclists face risks on the road that drivers of passenger vehicles simply do not. The data confirms what every rider already knows: when a crash happens, the consequences for a motorcyclist are far more severe than for someone inside a car. Understanding where, when, and how motorcycle accidents happen in Massachusetts can help riders stay safer and help accident victims understand why their injuries deserve serious compensation.
The statistics below draw from the most recent data available from the National Highway Traffic Safety Administration (NHTSA), the Massachusetts Department of Transportation (MassDOT), and the Insurance Institute for Highway Safety (IIHS). Numbers shift slightly year to year, but the patterns are consistent.

According to the NHTSA, approximately 6,000 motorcyclists are killed in traffic crashes across the United States each year. In the most recent reporting year, there were an estimated 83,000 motorcyclist injuries nationwide.
Motorcyclists account for roughly 14% of all traffic fatalities in the U.S., despite representing only about 3% of all registered vehicles. Per vehicle mile traveled, motorcyclists are approximately 24 times more likely to die in a crash and four times more likely to be injured compared to passenger car occupants.
These national figures provide context for the Massachusetts-specific data below.
Massachusetts averages between 40 and 60 motorcyclist fatalities per year, depending on weather conditions, riding season length, and other factors. In recent years, the state has seen fluctuations in that range.
Massachusetts consistently ranks in the lower half of states for total motorcycle fatalities, largely because of its smaller geographic size and shorter riding season. However, the fatality rate per registered motorcycle in the state remains comparable to the national average, meaning riding in Massachusetts is not inherently safer than riding elsewhere.
Motorcycle crashes follow recognizable patterns. Understanding these patterns helps riders anticipate danger and helps accident victims identify who was at fault.
The single most dangerous scenario for a motorcyclist is a car making a left turn at an intersection. The driver either fails to see the approaching motorcycle or misjudges its speed and turns directly into its path. Left-turn collisions account for approximately 42% of fatal motorcycle-versus-car accidents nationwide according to NHTSA data. In Massachusetts, the congested intersection environments of Greater Boston, Worcester, and Springfield make left-turn crashes especially common.
Motorcyclists stopped at red lights, in traffic, or at stop signs are vulnerable to being struck from behind by distracted or inattentive drivers. Rear-end collisions that would be minor fender benders between two cars can be catastrophic for a motorcyclist, who has no rear crumple zone or seatbelt. These crashes often result in the rider being thrown from the motorcycle into the intersection or into other vehicles.
Not all motorcycle accidents involve another vehicle. Single-vehicle crashes caused by road hazards, including potholes, sand or gravel on the road surface, uneven pavement, and debris, account for a meaningful percentage of motorcycle accidents in Massachusetts. The state's aging road infrastructure and harsh winter weather create conditions that are particularly hazardous for two-wheeled vehicles. When a road defect causes a crash, the municipality or state agency responsible for maintaining the road may be liable.
Head-on crashes between motorcycles and passenger vehicles are the deadliest type of motorcycle accident. They account for a disproportionate share of motorcycle fatalities. These crashes often occur on two-lane rural roads where a vehicle crosses the center line. In Massachusetts, winding roads in the western part of the state and on Cape Cod see a higher incidence of head-on motorcycle accidents.
Motorcycle accidents in Massachusetts are heavily concentrated between May and October, which corresponds to the primary riding season. June, July, and August consistently record the highest numbers of motorcycle crashes and fatalities. September and October see a second spike as riders take advantage of fall foliage rides. Very few motorcycle accidents occur between December and March due to weather and reduced riding activity.
Weekend days, particularly Saturday and Sunday, see a disproportionate number of motorcycle accidents compared to weekdays. Recreational riding increases on weekends, and the routes riders choose for leisure, including winding rural roads and coastal highways, tend to carry higher crash risk than urban commuting routes.
NHTSA data shows that motorcycle fatalities peak between 3 p.m. and 9 p.m. nationally. In Massachusetts, late afternoon and early evening hours are the most dangerous for riders. This window combines rush-hour traffic volume, lower sun angles that impair driver visibility, and recreational riders returning home from day rides.
The average age of motorcyclists killed in crashes has been rising steadily for decades. Nationally, the median age of motorcycle fatality victims is now in the mid-to-late 40s. In Massachusetts, the trend is similar. Older riders tend to ride larger, more powerful motorcycles and may face longer recovery times from injuries. However, riders between 20 and 29 have the highest crash rate per miles ridden, reflecting less experience and higher risk-taking behavior.
In approximately 60% of fatal motorcycle crashes in Massachusetts, another vehicle is involved. In the majority of those multi-vehicle crashes, the other driver was at fault, most commonly by failing to yield the right of way, making an improper turn, or following too closely. In single-vehicle motorcycle crashes, road conditions, rider error, and mechanical failure are the primary contributing factors.
Alcohol involvement remains a significant factor in motorcycle fatalities. Nationally, approximately 27% of motorcyclists killed in crashes had a blood alcohol concentration (BAC) above the legal limit of 0.08%. Massachusetts numbers are generally consistent with the national average. Riding under the influence dramatically increases the severity and likelihood of a fatal outcome.
Massachusetts has a universal helmet law requiring all motorcycle riders and passengers to wear a helmet (Mass. Gen. Laws Ch. 90, §7). States with universal helmet laws consistently show lower motorcycle fatality rates than states without them.
According to the IIHS, helmets are estimated to be 37% effective in preventing motorcycle deaths and about 67% effective in preventing brain injuries. In states without helmet laws, helmet use drops dramatically, and fatality rates increase accordingly. New Hampshire, where Kiley Law Group also represents injured riders, is the only state in the U.S. that does not require motorcycle helmets for riders 18 and older.
Massachusetts's helmet law is one reason the state's fatality rate per registered motorcycle is slightly lower than the national average. But helmets do not prevent crashes, and they do not protect riders from the most common motorcycle accident injuries: broken bones, road rash, spinal injuries, and internal organ damage.
The data tells a clear story. Motorcycle accidents produce injuries that are more severe, more expensive, and more life-altering than crashes involving passenger vehicles. The disproportionate severity of motorcycle injuries is reflected in the compensation these cases are worth.
Do not let an insurance adjuster use bias against motorcyclists to reduce what you are owed. The statistics are on your side. An experienced motorcycle accident attorney will use the data and the facts of your case to build the strongest possible claim.
Massachusetts records approximately 1,500 to 2,000 motorcycle crashes per year, with 40 to 60 of those resulting in fatalities. The exact numbers fluctuate based on riding season weather, gas prices, and other factors that affect how many miles riders log. The majority of crashes occur between May and October.
The most common cause is another driver failing to see or yield to the motorcyclist. Left-turn collisions, where a car turns into the path of an oncoming motorcycle, are the single most frequent crash type. Distracted driving, failure to check blind spots, and following too closely are also leading causes.
Yes. Per vehicle mile traveled, motorcyclists are approximately 24 times more likely to die in a crash and four times more likely to be injured compared to car occupants, according to NHTSA data. The lack of structural protection, airbags, and seatbelts means motorcyclists absorb the full force of any impact.
In multi-vehicle motorcycle accidents, the other driver is at fault in approximately 60% to 70% of cases nationally. The most common driver error is failing to yield the right of way, often because the driver did not see the motorcycle. Despite this, insurance companies frequently attempt to assign partial blame to the rider.
Yes. Helmets are estimated to be 37% effective at preventing motorcycle deaths and approximately 67% effective at preventing brain injuries, according to the IIHS. Massachusetts requires all riders and passengers to wear helmets under Mass. Gen. Laws Ch. 90, §7. However, helmets do not prevent the most common motorcycle injuries, including broken bones, road rash, and spinal damage.
