Frequently Asked Questions
What is an underride crash?
An underride crash happens when a smaller vehicle slides partly or fully beneath a larger truck's body during a collision, usually because the truck's frame sits higher than the car's crumple zones. These crashes can cause more serious injuries than a typical collision because the car's safety structure is bypassed.
What usually causes large-truck accidents?
Common factors include driver fatigue, blind spots, long stopping distances, mechanical failure, and misjudged turns or lane changes in congested areas. Weather and road conditions can also play a role.
How can drivers share the road safely with trucks like dump trucks?
Give trucks extra space, especially around turns and intersections where they need a wider path. Avoid lingering in blind spots, and assume the truck driver may not see you unless you can see their mirrors.
Does fatigue play a role in truck crashes?
Yes. Long hours behind the wheel can slow reaction time and impair judgment, which is why hours-of-service rules exist for commercial drivers. Fatigue is a factor investigators usually examine in truck-involved crashes.
What to Do After a Truck Crash in Portsmouth, NH
If you're involved in a crash with a dump truck or other large vehicle, move to a safe spot if possible and call 911 right away. Even if injuries seem minor at first, it's worth getting checked by a medical professional, since adrenaline can mask pain from impact.
Exchange information with the other driver and note any details you can, such as the truck's company markings or the responding agency. If officers arrive, ask how to obtain a copy of the official report once it's filed. Keep records of any medical visits or vehicle damage in the days that follow, as these can matter later even if you're not yet sure how serious the impact was.
