How Is Fault Determined After a Multi-Vehicle Accident in Andover, MA?

Fault after a multi-vehicle accident in Andover depends on how each driver acted and whether careless behavior contributed to the crash. Investigators review vehicle damage, roadway marks, witness accounts, and camera footage. More than one driver may share responsibility.

Because pileups unfold within seconds, drivers rarely see the entire sequence from inside their vehicles. You may feel certain about what happened yet miss an important detail. Stress and pain can also make it difficult to remember each moment clearly.

Around Andover, Interstate 495 carries steady traffic near Route 133 and the Interstate 93 interchange. Passenger vehicles and commercial trucks share this busy corridor, where merging traffic, lane changes, and sudden slowdowns can quickly lead to chain-reaction crashes.

With several vehicles involved, each insurance company may develop a different account of what happened. Adjusters compare driver statements with physical evidence, but they may disagree about who caused the first contact. Those disagreements can delay a final fault decision.

Under Massachusetts law, you may still recover compensation when your share of fault is 50 percent or less. However, your compensation decreases according to your percentage of responsibility. Even a small change in that percentage can affect your financial recovery.

As insurance disputes begin to grow, evidence can disappear while you focus on medical care. Roadway marks may fade, recordings can be erased, and witnesses may forget key details. A Massachusetts car accident lawyer can preserve proof and challenge unfair blame.
