An FMCSA rule restricts the use of all hand-held mobile devices by drivers of commercial motor vehicles (CMVs). This rulemaking restricts a CMV driver from holding a mobile device to make a call, or dialing by pressing more than a single button. CMV drivers who use a mobile phone while driving can only use a hands-free phone located in close proximity.
Research commissioned by FMCSA shows that the odds of being involved in a safety-critical event (e.g., crash, near-crash, unintentional lane deviation) are 6 times greater for CMV drivers who engage in dialing a mobile phone while driving than for those who do not. Dialing drivers took their eyes off the forward roadway for an average of 3.8 seconds. At 55 mph (or 80.7 feet per second), this equates to a driver traveling 306 feet, the approximate length of a football field, without looking at the roadway!
