According to new research from the Insurance Institute for Highway Safety, vehicles that have automatic braking systems are likely to be involved in rear-end crashes much less than their counterparts who do not have these systems.

The research was specifically focused on forward collision warning and automatic emergency braking systems as well as the system suite created by Volvo known as City Safety. The suite of systems is an advanced version of the previous two technologies. The research looked at vehicles from various auto-makers such as Honda, Mercedes-Benz, Volvo, Subaru, and Acura as well as vehicles that had no crash prevention technology or just the forward collision warning technology.

Vehicles that had both the auto-braking and warning systems experienced reduced rates of rear-end car crashes to the tune of 39%. Crashes with injuries were reduced by 42%. Overall, that’s a decrease of crashes by 12% and a reduction in injury crashes by 15%. This technology, therefore, seems to be very effective at reducing some of the most devastating car accidents that you can experience.

Individuals involved in a rear-end collision may have serious injuries that result, especially whiplash. An individual who has been hurt in an accident like this may take several weeks, months or even years to recover depending on the extent of the injuries.
