The updated ratings place more focus on protecting both front and rear passengers during crashes. Vehicles must also perform well in crash prevention and pedestrian safety tests to earn top awards.
Only a small number of pickup trucks earned IIHS safety awards under the new requirements, showing that many models still need improvements to meet the higher standards.
IIHS says the new testing is designed to encourage manufacturers to build safer trucks for drivers, passengers, and everyone sharing the road.
Industry experts expect the updated ratings to influence future truck designs and give buyers more information when comparing new models.
