A new study from the Insurance Institute for Highway Safety’s Highway Loss Data Institute (HLDI) has found that Mazda’s advanced driver assistance systems can significantly reduce crash-related insurance claims, particularly when multiple features are combined.
The analysis covered Mazda vehicles from model years 2015 to 2023, examining six ADAS bundles and four standalone systems. Technologies assessed included automatic emergency braking, lane departure prevention, high beam assist and driver monitoring systems.
According to HLDI, larger bundles of safety features, typically incorporating newer-generation systems, were associated with greater reductions in claim frequency.
The most basic bundle, which includes front AEB with forward collision warning, reduced property damage liability (PDL) claims by 13% and bodily injury liability (BIL) claims by 9%. The most comprehensive bundle, adding features such as pedestrian detection, adaptive cruise control, rear AEB and driver attention alert, reduced PDL claims by 39% and BIL claims by 21%, although the latter was not statistically significant.
Two systems, front AEB with pedestrian detection and rear AEB, delivered the most notable additional reductions: updated AEB systems improved prevention of vehicle-to-vehicle crashes, while rear AEB was particularly effective in reducing low-speed parking collisions.
Standalone systems also showed a measurable impact. Blind spot monitoring combined with rear cross-traffic alert reduced PDL claim frequency by nearly 10% and BIL claims by 13%. Other features, including curve-adaptive headlights and head-up displays, were linked to smaller reductions. Traffic sign recognition did not show clear benefits in this dataset, which HLDI attributed to system limitations or lower adoption rates.
While some ADAS features were associated with increased claim severity due to the cost of replacing sensors, overall losses, combining claim frequency and severity, were generally lower for vehicles equipped with Mazda’s safety systems.
“Another important factor is that crash avoidance systems primarily eliminate crashes that occur at slower speeds,” said Matt Moore, chief insurance operations officer at HLDI and the Insurance Institute for Highway Safety. “That takes low-dollar claims out of the equation and skews the average cost upward.”
Mazda said the findings support its approach to integrating multiple safety technologies across its vehicle line-up.
“As this independent analysis demonstrates, continual improvement of driver assistance technologies has real world impact,” said Jennifer Morrison, director of vehicle safety strategy at Mazda North American Operations. “We remain committed to advancing both the performance and availability of these systems in our pursuit of zero fatal crashes.”
The study highlights the role of bundled and continuously updated ADAS features in improving real-world safety outcomes.
