FAQ
Q: Why are freeway crashes that block multiple lanes especially dangerous?
A: When several lanes are obstructed, approaching drivers may have limited time to react, increasing the risk of secondary collisions.
Q: Why do rear-end crashes sometimes result in serious injuries?
A: Rear-end impacts can cause sudden deceleration, which may lead to significant injuries depending on vehicle speed and positioning at the time of impact.
Q: Can an investigation continue after the roadway reopens?
A: Yes. Even after traffic resumes, investigators may continue reviewing evidence, vehicle damage, and witness statements to determine what caused the crash.
