FAQ
Q: Why can injuries appear hours after a highway accident?
A: After a crash, adrenaline may temporarily mask pain. Symptoms such as stiffness, headaches, or dizziness can develop later, making follow-up medical care important even when injuries initially seem manageable.
Q: Why are merging areas or intersections crash-prone?
A: Intersections require drivers to judge speed and distance accurately. Failing to yield or misjudging oncoming traffic can lead to side-impact collisions, which may result in rollovers or significant vehicle damage.
Q: What does it mean when an accident is under investigation?
A: An investigation indicates officers are reviewing evidence, vehicle positions, and statements to determine how the crash occurred and whether any traffic laws were violated.
