Car Accidents in Massachusetts: When Are You Most at Risk?
There were almost 100,000 crashes in Massachusetts in 2024. This article looks at when and why these accidents happen, as well as how timing, weather, location, and people’s actions can make you more likely to be in one. We’ll look at the differences between morning and evening rush hours, weekdays and weekends, seasonal patterns, high-risk intersections, and rural roads. We’ll also tell you when to be extra careful on Massachusetts roads.
Risk Patterns by Day and Time
Peak Time in the Evening (5 to 6 p.m. on weekdays)
The most dangerous time to drive in Massachusetts is during the evening rush hour, especially between 5 and 6 p.m. Crash data from several sources shows that this time of year always has the most accidents and deaths. People who drive to work are often tired, traffic is heavy, and aggressive driving rises. Sun glare in some months and people rushing home make things more dangerous.
The morning rush is from 7 to 9 a.m.
There is also a higher risk of crashes during the morning commute. But even though there are a lot of crashes, they are usually not as bad because the speeds are usually lower. Most of the accidents that happen during this time are rear-end collisions because traffic is stop-and-go. Lack of focus and drowsiness are common causes.
Driving at Night
If you drive at night, your chances of being in a deadly crash go up a lot. Driving at night is almost three times more likely to kill someone than driving during the day. Reduced visibility, tiredness, and driving while impaired are all major causes. Data shows that there are more DUI-related accidents at night, especially on weekends.
Risk on the weekend (especially Saturdays)
There are different kinds of risks on the weekends. Saturdays, in particular, see a big rise in crashes, which are often caused by drinking, driving while distracted, and going on vacation. A lot of these crashes happen late at night or early in the morning, when it’s hard to see the road and people aren’t very alert.
Table of Crash Risk by Time of Day
| Time of Day | Crash Frequency | Risk of Death | Common Causes |
| 7–9 a.m. on weekdays | Very High | Moderate | Drowsiness, rear-end collisions |
| 5–6 p.m. on weekdays | Highest | High | Aggressive driving, traffic jams |
| Night (9 p.m. to 3 a.m.) | Moderate | Highest | Drunk driving, poor visibility |
| Weekends | High | High | Alcohol, speeding, distractions |
Risk Factors for the Season and the Environment
Winter (snow and ice)
Massachusetts winters are especially dangerous. Snow and black ice make it much harder to drive, especially on rural roads that aren’t well maintained. Jason Ranallo says that crashes in the winter are more likely to cause serious injuries, especially when drivers aren’t ready or don’t slow down.
Spring (wet roads, potholes, deer at dawn and dusk)
There are new dangers in the spring. Rain makes roads wet, frost melts and makes potholes, and deer are more active at dawn and dusk, which all make crashes more likely. Motorcyclists also get back on the road in the spring, often before other drivers are fully aware of them.
Summer and Fall
The best times to travel are in the summer and fall. There are a lot of vacationers, young drivers, and tourists on the roads who don’t know the local traffic rules. Deer crossings go up in the fall, especially in the early morning and evening. Speeding is a big problem during these times.
Risks Related to Geography and Road Design
High-Risk Intersections (in cities and suburbs)
Intersections in cities are where a lot of serious accidents happen. Data shows that 41% of serious injuries happen at intersections, where people often don’t yield, make aggressive turns, and get confused. Crash clusters are common near busy crossings and shopping areas in places like Quincy and Brockton.
Rural Roads (like those in Plymouth and Mendon)
Rural roads may seem safer because there is less traffic, but they have higher death rates. These roads don’t always have enough lighting, signs, or shoulder space. They are especially dangerous in towns like Plymouth, Mendon, and Belchertown because of wildlife crossings, bad winter maintenance, and high speeds.
I-95 and Route 128 are busy highways during rush hour
During rush hour, there are a lot of accidents on big highways like I-95 and Route 128. Rear-end and T-bone crashes happen when people merge too quickly, drive while distracted, or tailgate. About 23% of all crashes are T-bone crashes.
Areas with a Lot of Risk — Quick List
Quincy, Brockton: crashes at city intersections
Plymouth, Mendon: deadly crashes in rural areas
Route 128 & I-95: rush hour accidents
Springfield, Worcester: complex traffic patterns
People’s Behavior and Most Common Crash Causes
Driving too fast and not paying attention
About 93% of all traffic accidents are caused by human error. Common issues: texting, eating, changing GPS settings.
Driving While Drunk and Tired
Crashes caused by alcohol are more severe and more likely to be fatal. Motorcycle crashes also increase on weekends due to driver impairment.
Not yielding and unsafe lane changes
Many T-bone and side-impact crashes happen when drivers fail to yield or merge recklessly. Around 40% of motorcycle crashes involve drivers not yielding.
