The Insurance Institute for Highway Safety offers consumers valuable data about current automobiles. By compiling and analyzing claims information, the data helps drivers choose the safest vehicle available when considering what car to purchase.

The most recent issue of the IIHS Status Report, published Sept. 20, contains a table of personal injury protection (PIP) claims for cars manufactured between 2009 and 2011. It also ranks the 10 most dangerous cars on the road by that metric.

The data shows that smaller cars were involved in accidents with the most frequency. This is partially a matter of physics, since a small car is more likely than a large car to sustain damage in the event of a collision. But according to Matt Moore, vice president of the Highway Loss Data Institute, a driver’s income, location, and rate of use can also come into play.

See the article for the full list of the top 10 bad luck cars and see below for the number 1 car on the list:

1. Toyota Yaris

The Yaris is one of the smallest cars manufactured by Toyota, and it has the highest claim frequency of any car in the IIHS report. In terms of its small size, it fits the profile of the other vehicles on this list, but at 28.5 claims filed per 1,000 insured vehicle years, it receives “about twice the average” number of PIP claims among 2009-2011 models, according to the IIHS.

The 2009-2011 Yaris models receive a score of “marginal” in their overall and dynamic ratings on the IIHS site.
