Massachusetts logs roughly 100,000 reported crashes every year. If you’re reading this, you may have just been in one of them. Knowing what to do after a car accident in Boston can protect both your health and your legal rights in the critical hours and days ahead.
Most guides give you a generic checklist. This one walks you through a real timeline, because the steps that matter on Day 1 are different from the ones that matter in Week 3.
The First 10 Minutes at the Scene
Your priority is safety, then documentation.
- Move to safety. If your car is drivable, pull to the shoulder or a nearby parking lot. Turn on hazard lights.
- Call 911. Even for minor collisions. A police report becomes critical evidence later.
- Check for injuries. If anyone is hurt, do not move them unless there’s immediate danger (fire, traffic).
- Exchange information. Get the other driver’s name, license number, insurance details, and plate number.
Do not apologize or say “I’m fine” at the scene. Under Massachusetts comparative negligence law, those words can be used to reduce your compensation later. Even saying “sorry” can be twisted into an admission of partial fault.
Document Everything
Pull out your phone and capture:
- Photos of all vehicles from multiple angles, including damage close-ups
- The intersection or road where it happened, including traffic signals and signs
- Skid marks, debris, or road conditions
- The other driver’s license plate and insurance card
- Any visible injuries on yourself or passengers
If there are witnesses, ask for their names and phone numbers. Witness statements carry significant weight in disputed claims.
The First 24 Hours
File Your Crash Report
Massachusetts law requires you to file an RMV crash report within 5 days if anyone was injured, someone died, or property damage exceeds $1,000. Most Boston accidents clear that threshold easily.
File it even if you think the damage is minor. Gaps in documentation give insurance companies room to question your claim.
See a Doctor
This is the step people skip, and it costs them the most. Go to the ER, urgent care, or your primary care physician within 24 hours.
Here’s why timing matters. Massachusetts is a no-fault state with mandatory Personal Injury Protection (PIP) coverage. Your PIP policy covers up to $8,000 in medical expenses regardless of who caused the crash. But to access it, you need documented injuries.
More importantly, if your medical bills exceed $2,000 or you have a permanent injury, you clear the “serious injury threshold.” That’s what allows you to sue the at-fault driver for pain and suffering beyond what PIP covers.
Example: You rear-end someone at a red light on Storrow Drive. Your neck hurts, but you skip the doctor for a week. By the time you go, the insurance company argues the delay means your injury isn’t related to the crash. That argument works more often than it should.
Week 1: Notify Your Insurance and Start a File
Contact Your Insurance Company
Report the accident to your own insurer within a few days. Stick to the facts: date, location, other driver’s info, and that you’re seeking medical treatment. Do not give a recorded statement to the other driver’s insurance company without legal advice.
Build Your Paper Trail
Start a folder (physical or digital) with:
- The police report (request a copy from Boston PD)
- All medical records and bills
- Photos from the scene
- A daily pain journal noting how your injuries affect work, sleep, and daily activities
- Receipts for any accident-related expenses (medications, rideshares to appointments, lost wages)
This file becomes the foundation of your claim. The more organized it is, the harder it is for an adjuster to lowball you.
How Massachusetts Comparative Negligence Affects Your Case
Massachusetts follows a modified comparative fault rule. You can recover damages as long as you are less than 51% at fault. But your compensation is reduced by your percentage of fault.
Here’s what that looks like in practice:
| Your Fault % | Total Damages | You Recover |
|---|---|---|
| 0% | $100,000 | $100,000 |
| 20% | $100,000 | $80,000 |
| 40% | $100,000 | $60,000 |
| 51% | $100,000 | $0 |
This is why what you say at the scene matters. If the police report notes that you said “I didn’t see them,” that statement can shift fault allocation by 10-20 percentage points. That’s tens of thousands of dollars in a serious injury case.
Month 1-3: Treatment, Documentation, and the Claim Process
Focus on recovery during this period. Follow your doctor’s treatment plan consistently. Gaps in treatment are the number one tool insurance adjusters use to devalue claims.
If your injuries are serious, this is typically when you should consult with a personal injury attorney. Most offer free consultations and work on contingency, meaning you pay nothing unless you recover compensation.
What a Typical Timeline Looks Like
| Timeframe | What Happens |
|---|---|
| Day 1 | Accident, police report, ER visit |
| Days 2-5 | File RMV crash report, notify insurer |
| Weeks 1-4 | Follow-up medical appointments, build documentation file |
| Months 1-3 | Ongoing treatment, attorney consultation if needed |
| Months 3-6 | Demand letter sent to insurer, negotiation begins |
| Months 6-12 | Settlement or litigation |
Not every case takes a year. Minor injury claims with clear liability can settle in 2-3 months. Complex cases involving multiple vehicles or disputed fault take longer.
Boston-Specific Factors That Affect Your Case
Boston has unique conditions that create specific accident scenarios:
- Rideshare accidents. Uber and Lyft accidents involve a third insurance policy (the rideshare company’s), which complicates the claims process but can increase available coverage.
- MBTA and city vehicle accidents. Claims against the city or the T have shorter notice deadlines and specific procedural requirements under Massachusetts tort claims law.
- Winter conditions. Ice and snow contribute to a significant share of Boston crashes between November and March. Poor road maintenance by the city can shift liability to the municipality.
- Construction zones. With ongoing infrastructure projects across Boston, construction zone accidents may involve contractor liability in addition to driver fault.
When to Contact a Personal Injury Lawyer
Not every accident requires an attorney. For minor fender-benders with no injuries and clear liability, you can likely handle the insurance claim yourself.
You should talk to a lawyer if:
- Your medical bills exceed $2,000 (clearing the serious injury threshold)
- You missed work for more than a few days
- The other driver’s insurance is disputing fault
- Multiple vehicles or parties are involved
- You were hit by a commercial truck, rideshare, or government vehicle
- The insurance company’s first offer feels low
The 3-year statute of limitations in Massachusetts gives you time, but evidence deteriorates and witnesses forget. Starting the process earlier leads to better outcomes.
