AAA Mid-Atlantic is warning drivers to be extra mindful on Monday after Daylight Saving Time kicks in.

The annual scheduled clock hopping is happening on Sunday (March 11), “springing forward” an hour starting at 2 a.m.

Only 31.9 percent of Washingtonians get seven hours of sleep per night, according to AAA, and it can take two weeks for the body to adjust to the time turning.

Even losing one hour’s sleep can disrupt the body’s circadian rhythm enough to cause damage. Health risks include strokes, heart attacks, obesity, diabetes, and workplace- or traffic-related accidents.

Drowsy driving in particular is a concern in AAA’s eyes citing the “major threat on area roadways Monday” morning and calling it “one of the most underreported traffic safety issues.”

The automotive organization’s warning points to its own drowsy driving research.

Remarkably, the percentage of crashes involving drowsiness is nearly eight times higher than federal estimates indicate, according to the AAA Foundation for Traffic Safety. The difficulty in detecting drowsiness following a crash makes drowsy driving one of the most underreported traffic safety issues. The new research provides an unprecedented analysis of in-vehicle dashcam video from more than 700 crashes, confirming that the danger of drowsy driving soars above official estimates. This weekend, millions of drivers will have difficulty springing forward. Come Monday, the prevalence of short sleep will loom large.

In the study, researchers examined video of drivers’ faces in the three minutes leading up to a crash.
Using a scientific measure linking the percentage of time a person’s eyes are closed to their level of drowsiness, the researchers determined that 9.5 percent of all crashes and 10.8 percent of crashes resulting in significant property damage involved drowsiness. Federal estimates indicate drowsiness is a factor in only one to two percent of crashes.

Even so, 35 percent of drivers in the United States sleep less than the recommended minimum of seven hours daily, notes the Centers for Disease Control and Prevention (CDC). In a recent related AAA Foundation survey, nearly all drivers (96 percent) say they view drowsy driving as a serious threat to their safety and a completely unacceptable behavior. However, 29 percent admitted to driving when they were so tired they had a hard time keeping their eyes open at some point in the past month.

Drowsy driving warning signs include struggling to keep your eyes open, lane drifting, and not remembering the last few miles driven.

To avoid drowsy driving, AAA recommends drivers travel when they normally would travel, avoid heavy foods and other sleep-inducing medications, and, for longer trips, schedule breaks every two hours for every 100 miles driven with an alert passenger who can take turns driving.
