After a crash, you may remember the other driver looking down at a phone or turning away from traffic just before impact. But how do you show that distraction caused the accident—especially if the driver denies it?

Evidence used to prove distracted driving in Massachusetts can include cellphone records, witness statements, police reports, dashcam or security footage, and vehicle crash data. These sources can help establish what the driver was doing and how it contributed to the collision. A successful negligence claim must connect the driver’s failure to use reasonable care with the crash and your resulting injuries.

Gathering that evidence can feel overwhelming when you are also managing medical appointments and vehicle repairs. Still, acting early can make a difference. Recordings may be overwritten, electronic records can become unavailable, and memories fade. Understanding where to look—and what each type of evidence can show—can help you protect your claim.

The consequences of distraction can be serious. According to the National Highway Traffic Safety Administration, 3,208 people died in crashes involving distracted drivers nationwide in 2024. Understanding what evidence is available can help you protect your ability to pursue compensation.

Key Takeaways: Evidence Used to Prove Distracted Driving in Massachusetts

• Several types of evidence can establish distraction: Phone records, video, witness observations, and vehicle data may help connect a driver’s inattention to the crash.
• A written crash report may be required: Massachusetts generally requires drivers to report qualifying crashes to the RMV and local police within five days.
• Digital evidence needs prompt attention: An attorney can request preservation of relevant records and footage, although a preservation letter does not guarantee that evidence will be retained.
• A citation does not automatically establish fault: The driver’s conduct and its connection to your injuries must still be proven.
• Context matters: A phone timestamp, spilled drink, or lack of skid marks alone does not establish that a driver was distracted.

Identifying Proof for Distracted Driving Claims in Massachusetts

Attorneys and insurance adjusters examine several categories of evidence when investigating a distracted driving crash. Collecting documentation after a Massachusetts car accident can help establish how the collision occurred and whether another driver failed to use reasonable care.

Relevant evidence may include:

• Electronic records: Call logs, message timestamps, and available account or device activity.
• Visual evidence: Photographs, dashcam recordings, and nearby security footage.
• Official records: Police crash reports, officers’ notes, and information about alleged traffic violations.
• Witness accounts: Observations from passengers, pedestrians, other drivers, and responding emergency personnel.

These sources serve different purposes. A witness might describe a driver looking down just before impact, while a dashcam shows the vehicle drifting out of its lane. Together, those details may provide a clearer account than either source alone.

Medical records and other documentation are also necessary to establish the injuries and losses caused by the crash.

What Evidence Can Show That a Driver Was Distracted?

Distraction can involve more than texting. Eating, adjusting the radio, or turning to speak to passengers can take a driver’s attention away from the road. Whether those actions support a negligence claim depends on what happened and how the distraction contributed to the collision.

Your observations can provide an important starting point. If you saw the other driver holding a phone, looking away from traffic, or reaching for something before impact, write down those details as soon as you can. Describe what you actually saw without guessing about what the driver was doing.

Physical evidence may provide additional clues. Investigators may consider tire marks, vehicle damage, roadway conditions, and the location of debris when reconstructing the crash. A lack of visible skid marks does not establish that the driver failed to brake or was distracted.

Spilled food, open makeup containers, or a phone near the driver’s seat may also provide leads. Their presence alone does not show what the driver was doing before impact because the collision may have moved or spilled them. Photographs can preserve those details for evaluation alongside other evidence.

How Can Cellphone Records Be Obtained and Used?

Attorneys may seek relevant cellphone records through civil discovery, requests for records in the driver’s possession, and legally authorized procedures involving telecommunications providers. Available information may include call records, message-related metadata, or other account activity, depending on the provider and applicable privacy restrictions.

Obtaining this evidence requires compliance with federal privacy laws and discovery rules. The federal Stored Communications Act restricts providers’ disclosure of certain electronic communications, particularly message content. An attorney may need to seek relevant information from the driver or the driver’s device rather than directly from the service provider.

Once records are obtained, investigators can compare their timestamps with the estimated time of the crash. A message sent or received near the collision may justify further investigation, but the timestamp alone does not establish that the driver was physically using the phone.

Device and application records may offer additional information when available. However, network activity can come from automatic updates or background processes. Witness observations, video, and other evidence can help determine whether the driver was actively distracted.

What Can Vehicle Data, Cameras, and Witnesses Reveal?

Depending on the vehicle and its recording systems, crash data may show speed, braking, and sometimes steering inputs in the seconds surrounding a collision. Nearby cameras and witness accounts may help explain what those technical details mean.

Many newer vehicles contain event data recorders that capture certain information around a crash. Investigators can compare the available data with roadway conditions, vehicle damage, and other evidence to evaluate the driver’s actions. Vehicle data alone cannot establish distraction, and extracting and interpreting it may require specialized equipment and qualified analysis.

Surveillance cameras on nearby buildings or dashboard cameras in other vehicles may capture the collision or the moments leading up to it. Depending on the angle, visibility, and recording quality, footage may show vehicle movements or driver behavior.

Independent bystanders may provide additional context. Someone who saw the driver looking down before impact may help connect the vehicle’s movements to a possible distraction. The value of that testimony depends on the witness’s opportunity to observe and the accuracy of the account. Collecting contact information at the scene makes follow-up interviews possible.

Does a Traffic Citation Prove the Injury Claim?

A police citation can identify conduct worth investigating, but it does not automatically establish that the driver caused the crash. The injured person must still establish negligence, a connection between the negligent conduct and the collision, and resulting damages.

Under M.G.L. c. 90, § 13B, drivers age 18 and older generally must use mobile electronic devices in hands-free mode. They may not hold a device, read texts, or watch videos. Viewing navigation maps on a properly mounted device is permitted.

These restrictions still apply while stopped at a red light. Handheld use is generally permitted only when the vehicle is stationary outside a travel or bicycle lane. Emergency exceptions apply.

Drivers under 18 face stricter rules under M.G.L. c. 90, § 8M. They generally may not use a phone while driving, even hands-free, and violations carry license suspensions in addition to fines.

The state’s hands-free guidance lists the following penalties for adult drivers:

Offense Level	Base Fine	Additional Consequences
First offense	$100	No mandatory distracted driving course under § 13B
Second offense	$250	Mandatory distracted driving educational program
Third and subsequent offenses	$500	Insurance surcharge and mandatory distracted driving educational program

A separate $5 statutory public safety surcharge applies to these fines.

Evidence of a relevant safety-law violation can support a negligence claim in Massachusetts, but it does not automatically establish civil liability. Also, under M.G.L. c. 90C, § 3, paying a civil traffic assessment cannot be used as an admission of negligence in the injury lawsuit.

Police reports can help document the crash, but not everything in a report can necessarily be used at trial. An officer’s factual observations, opinions, and recorded witness statements may be treated differently under the rules of evidence.

Separately, Massachusetts crash-reporting law generally requires drivers to submit a written report to the RMV and send a copy to the police department with jurisdiction within five days when anyone is injured or killed, or damage exceeds $1,000 to any one vehicle or other property. A driver who is physically unable to report is excused during that incapacity. If the driver is not the vehicle’s owner, the owner must submit the report within five days using the information available. A police investigation does not replace the driver’s separate reporting obligation.

Preserving Digital Evidence Before It Is Deleted or Overwritten

A formal evidence preservation letter can notify the other driver and relevant parties that specific records, footage, or vehicle data may be needed for anticipated litigation. The letter does not automatically prevent deletion or guarantee preservation.

Security systems may overwrite footage according to their storage settings. Messages, call histories, and other device information can also be deleted or become unavailable. Promptly identifying relevant sources and requesting preservation can improve the opportunity to obtain useful evidence.

Massachusetts courts may impose sanctions for improper destruction of relevant evidence, including in some circumstances before a lawsuit is filed. Whether sanctions are appropriate depends on the preservation duty and the facts. A missing record does not automatically establish wrongdoing, and a request to an unrelated third party does not necessarily create the same obligations as those of a potential litigant.

Preservation should also include relevant evidence in your possession. Keep original photographs, recordings, messages, and other crash-related records, and discuss their retention with your attorney.

Frequently Asked Questions About Evidence of Distracted Driving in Massachusetts

Can Social Media Activity Help Prove Distraction?

Social media posts, live streams, and photo uploads may provide evidence of activity near the time of a collision. However, a publication timestamp does not necessarily establish that the driver personally used the application while driving. Additional device records, witness statements, or other evidence may be needed to connect the activity to the driver and the crash.

What If the Driver Denies Using a Phone?

Eyewitness testimony, video, physical evidence, and legally obtained phone records may help establish what happened despite the driver’s denial. Investigators can compare these sources to identify inconsistencies and reconstruct events. The strength of the evidence depends on what it actually shows and how reliably it connects the driver’s conduct to the collision.

How Long Do You Have to File a Personal Injury Lawsuit?

Under M.G.L. c. 260, § 2A, Massachusetts negligence lawsuits for personal injuries generally must be filed within three years after the claim accrues. For car accident injuries, that is ordinarily the date of the collision, although exceptions and tolling rules may affect the deadline.

Claims against public employers under the Massachusetts Tort Claims Act have additional requirements, including written presentment within two years under M.G.L. c. 258, § 4.

Missing the applicable deadline can prevent recovery. Acting promptly also allows time to preserve evidence and address separate insurance and reporting requirements.
