AAA: Daylight saving time increases crash risk


Extra hour of sleep means sun glare, lower visibility, fatigue

DAYTON – With the end of daylight saving time (2 a.m. Sunday, Nov. 3), motorists need to prepare for changes during their commutes that could impact driver and pedestrian safety. AAA warns motorists to be prepared for sun glare during their morning commute and reduced visibility on the road as darkness comes to their evening commute.

“Ninety percent of drivers’ reaction time is dependent upon their vision, which is severely limited once darkness falls,” said Kara Hitchens, AAA spokesperson. “Motorists have gotten used to nearly eight months of daylight for their evening commutes, but that’s about to change. Sunset is one of the most challenging times to drive because motorists’ eyes are frequently adjusting to the increasing darkness. That’s why motorists are encouraged to focus on night driving safety measures as daylight saving time comes to an end.”

AAA recommends wearing high-quality sunglasses and adjusting the car’s sun visors as needed. Late afternoon driving also presents a glare problem, so drivers should take similar precautions. Use of the night setting on rear-view mirrors can reduce glare from headlights approaching from the rear.

Changes in behavior increase risk

The time change can cause disturbed sleep patterns, and when combined with the earlier dusk and darkness during the evening commute, become a formula for drowsy driving and fatigue-related crashes.

Researchers at Stanford University and Johns Hopkins University, along with the Insurance Bureau of British Columbia, found that changes in motorist behavior as daylight saving time ends are also likely contributing to an increased risk of vehicle crashes, an effect that has been shown to last up to two weeks following the time change. It’s believed motorists stay up later than usual, anticipating they’ll get an extra hour of sleep, then end up driving drowsy the next day.

“With an increase in deer movement and lower visibility this time of the year, it’s critical to drive alert whenever you’re behind the wheel,” said Hitchens. “Driving drowsy is an underrated risk with serious consequences.”

The difficulty in detecting drowsiness following a crash makes drowsy driving one of the most under-reported traffic safety issues. The percentage of crashes involving drowsiness is nearly eight times higher than federal estimates indicate, according to the AAA Foundation for Traffic Safety. Last year, the Foundation released findings of the most in-depth drowsy driving research ever conducted in the U.S., providing an unprecedented analysis of in-vehicle dash-cam video from more than 700 crashes. The results confirmed that the danger of drowsy driving is much greater than official estimates might suggest.

“Everyone looks forward to an extra hour of sleep, but motorists often overlook the added dangers that can come as the result of a time change when they are behind the wheel,” continued Hitchens. “Although we gain an hour of sleep, our sleep patterns are disrupted and there is the temptation to stay up later at night. This can result in drowsy driving episodes that put drivers and pedestrians at greater risk.”

Symptoms of drowsy driving can include having trouble keeping eyes open, drifting from lanes or not remembering the last few miles driven. However, more than half of drivers involved in fatigue-related crashes experienced no symptoms before falling asleep behind the wheel.

AAA tips for drivers

– Get plenty of rest before getting behind the wheel of a vehicle. If you do begin to feel drowsy while driving, pull over immediately and rest, or call a family member, friend or 911 for assistance.

– Reduce speed and increase following distances.

– Turn on your headlights to become more visible during early morning and evening hours.

– Keep vehicle headlights and windows (inside and out) clean.

– Do not use high beams when other cars or pedestrians are near.

– Yield the right of way to pedestrians in crosswalks and do not pass vehicles stopped at crosswalks.

AAA tips for pedestrians and cyclists

– Cross only at intersections. Look left, right and left again and only cross when it is clear. Do not jaywalk.

– Avoid walking in traffic where there are no sidewalks or crosswalks. If you have to walk on a road that does not have sidewalks, walk facing traffic.

– Evaluate the distance and speed of oncoming traffic before you step out into the street.

– Wear bright colors or reflective clothing if you are walking or biking near traffic at night. Carry a flashlight when walking in the dark.

– Avoid distracted walking. This includes looking at your phone, wearing headphones or listening to music.

– Bicycle lights are a must-have item for safe night riding, especially during the winter months when it gets dark earlier.

Time to check smoke detectors

It’s time to check smoke detectors and change their batteries every time daylight saving time starts and ends. The state Fire Marshal’s Office also recommends having a smoke detector inside each bedroom and on each level of a house.
