    New crash tests and analysis by IIHS demonstrate that underride guards on tractor-trailers can fail in relatively low-speed crashes — with deadly consequences.

    New work rule for truckers isn't improving safety

    A new IIHS survey indicates that drivers of interstate trucks spend more time behind the wheel under a federal work rule that went into effect in 2004.

Eight of 10 drivers said they're taking advantage of a restart provision that allows them to drive 25 percent more in a week.
