A recent study shows that blind zones in newer vehicles are becoming larger, obstructing drivers’ vision and reducing safety.

The study, conducted by the Insurance Institute for Highway Safety (IIHS), analyzed six popular vehicles: Chevrolet Suburban, Ford F-150, Honda Accord, Honda CR-V, Jeep Grand Cherokee, and Toyota Camry. It found that over the past 25 years, the blind zones in these vehicles have significantly increased, affecting forward visibility.

Key Findings:
— Blind zones have expanded, especially in SUVs, leading to a 58% decrease in forward visibility for some models.
— The Honda CR-V saw the most significant reduction, with visibility dropping from 68% to 28% over time.
— Factors like higher hoods, larger mirrors, and wider A-pillars are the main contributors to this reduced visibility.

The research used a new method developed by the IIHS, combining computational software and a portable camera rig to create accurate blind zone maps.

Visibility Reductions:
— Honda CR-V: 68% visibility in 1997 → 28% in 2022.
— Chevrolet Suburban: Significant increase in blind zones due to higher hoods and larger mirrors.
— Toyota Camry: Small decrease in visibility (61% in 2007 → 57% in 2023).

Impact on Road Safety:
The study raises concerns about the role of decreased visibility in the recent increase in pedestrian and bicyclist fatalities. With SUVs becoming more common, the reduction in visibility could worsen these safety issues.

The IIHS is planning further research to explore the connection between blind zones and pedestrian crash rates.
