Why Do Pedestrian Accidents Like This Occur?

Pedestrian safety on U.S. roads has deteriorated, driven by factors such as the rise in larger vehicles like SUVs and trucks, high-speed road designs, and driver inattention. Data from the Insurance Institute for Highway Safety (IIHS) shows that 84% of pedestrian fatalities in 2023 happened in urban areas, compared to 59% in 1975.

Legal Insights

National legal analysts emphasize the importance of thorough investigations in pedestrian collisions to identify potential negligence.

“In most instances, pedestrians possess the right of way when crossing an intersection or a street regardless of whether they are in a marked crosswalk,” said Candice Bond, managing partner of Bond Legal.

Bond highlighted the need for independent investigations in such cases to safeguard victims' rights.

“Having the right resources is essential in any pedestrian accident investigation, helping ensure evidence is collected, reviewed, and documented properly so investigators can determine whether negligence played a role,” Bond added.

Pending investigation outcomes, affected families may pursue wrongful death claims to seek compensation for loss and emotional distress.

“The stress and sorrow can be extremely overwhelming after losing a loved one in an accident,” said Stefano Formica, of counsel with Bond Legal.
