Frequently Asked Questions
What makes crashes involving garbage trucks or other large trucks more dangerous than typical car crashes?
Large trucks weigh far more than passenger cars, so a collision transfers much greater force into the smaller vehicle. Size and weight differences usually mean more severe injuries for people in the car even at moderate speeds.
What are a truck's blind spots and why do they matter?
Garbage trucks and other large trucks have wide blind spots along the sides, front, and rear. Drivers and pedestrians near a truck at an intersection can be difficult for the truck operator to see, which can contribute to crashes during turns or stops.
What is an underride crash?
An underride crash happens when a smaller vehicle slides partly or fully beneath a truck's trailer or body during a collision. These crashes can cause severe damage to the car's upper frame and are a particular hazard in intersection or rear-end collisions with large trucks.
What are common causes of large-truck accidents?
Common factors include limited visibility, wide turning patterns, following distance, and intersection timing. Investigators typically examine speed, right-of-way, and road conditions before determining a cause.
What to Do After a Car Accident in Marengo, Illinois
If you're involved in a crash with a large truck, try to move to a safe spot away from traffic if you're able, and call 911 right away. Even if injuries seem minor at first, ask for a medical evaluation at the scene or soon after. Some injuries, especially from impacts with a large vehicle, aren't obvious right away. Get the names and badge numbers of responding officers, and ask how to obtain a copy of the official crash report once it's filed. If you're able, take photos of vehicle positions and damage before vehicles are moved. Keep track of any medical visits and follow-up care related to the crash.
