The Insurance Institute for Highway Safety ran roof strength tests on five small truck models, and all of them passed but the Institute says manufacturers could do better.
Nearly 10,000 people a year die in rollover crashes, often when the roof gets crushed.
The Nissan Frontier fared the best, earning a rating of good in terms of roof strength.
Ford's Ranger was not far behind with an acceptable rating.
Three others received a marginal rating, they include the Dodge Dakota, the Toyota Tacoma and the Chevy Colorado.
Manufacturers of those three say their trucks meet or exceed federal safety standards and are among the safest of all vehicles on the road.
Here's some additional information on what some automakers had to say about the rollover test.
Excerpt from Toyota statement:
All 2010 Tacoma models are rated as 4 stars for rollover protection by the National Highway Traffic Safety Administration (NHTSA). Further, if using the IIHS calculations for rollover protection, the Tacoma's IIHS score would far exceed the NHTSA safety requirement.
Excerpt from Chrysler statement, re: Dodge Dakota
The 2010 Dodge Dakota received 5-stars in the Government's side impact crash test by the National Highway Traffic Safety Administration (NHTSA) for driver and rear passenger. The vehicle is equipped with standard advanced multi-stage front driver and passenger air bags and offers supplemental side curtain air bags. Chrysler, Dodge, Jeep and Ram vehicles meet or exceed all applicable Federal Safety standards.
Excerpt from GM statement, re: Chevy Colorado
All GM vehicles, including the Chevrolet Colorado, meet government safety standards -- as documented by results in a range of NHTSA conducted crash tests -- so we were disappointed to see IIHS rate the vehicle as "marginal". We believe the overall design of the vehicle and the safety features included still make it a good choice for customers looking to purchase a small pick-up truck.
