Why truck blind zones make lane-change crashes harder to prove

On Behalf of | Jun 18, 2026 | Truck Accident

A lane-change crash involving a tractor-trailer can leave you injured, overwhelmed and questioning how the driver failed to recognize a nearby vehicle. Large commercial trucks have wide blind spots, often called “No-Zones.” According to the Federal Motor Carrier Safety Administration, one-third of collisions between large trucks and cars take place in these areas.

Because Maryland applies a strict contributory negligence standard, these cases can become more challenging when an insurer argues that your own actions contributed to the collision.

Why fault is often disputed

One significant obstacle in your claim is the state’s contributory negligence doctrine. In Maryland, if you are found even slightly responsible, even 1%, you may be barred from recovering compensation for your injuries, property damage and other losses.

This is why fault is so often disputed in these cases. State law requires a driver to stay in one lane and move only when it is safe. However, the insurer may still examine your conduct and argue that you contributed in some way to the collision.

They may argue that you stayed in a blind spot too long, sped up while the truck had its turn signal on, had poor headlight visibility or changed lanes improperly just before the crash. If those arguments are accepted, the insurer could deny compensation.

What evidence can show what happened

Blind-zone crashes often depend on time-sensitive details that can disappear before investigators fully review the claim. Independent evidence can support your account and challenge allegations that you were partly responsible. Useful information may include:

  • Photos and videos of the vehicle damage, road marks and the entire crash scene
  • Contact information for any witnesses who saw what happened
  • Footage from your dashcam, nearby traffic cameras or business security cameras
  • The official police report
  • The truck’s electronic data from its “black box,” which can show speed and braking information

These materials can help establish vehicle position, timing, visibility and the truck’s movement before impact.

Protect evidence before details disappear

After a blind-zone collision, the insurer may focus on small details to argue that you contributed to the crash. Acting early gives you a better chance to preserve the facts needed to respond. The clearer the evidence is, the harder it may be for blame-shifting arguments to control the outcome.
