IIHS studies show better detection of large trucks, motorcycles would improve front crash prevention

Front crash prevention systems aren’t as good at preventing crashes with large trucks and motorcycles as they are crashes with cars, two new studies from the Insurance Institute for Highway Safety show.

Most front crash prevention systems include forward collision warning and automatic emergency braking (AEB). Forward collision warning alerts the driver when a rear-end crash is imminent, and AEB automatically slams on the brakes if the driver fails to respond in time.

Today’s systems reduce rear-end crash rates with medium or heavy trucks by 38% and rear-end crash rates with motorcycles by 41%, compared with a 53% reduction in rear-end crash rates with other passenger vehicles, an IIHS study of more than 160,000 crashes found. The same discrepancy is seen with the surrogate vehicle targets that IIHS and other organizations use to evaluate system performance, another study demonstrated.
