Safety Topic - Driving After Dark
9/28/2016 2:25:47 PM

As we head into the fall months and the days get shorter, take precautions when driving at night. Driving after dark is the most dangerous time to drive as more accidents happen between dusk and dawn. Nighttime driving can be more difficult if someone has vision problems. During the holiday season, more people are on the road during the evening hours as they are traveling to and from holiday parties and events.

According to the National Safety Council, "traffic deaths are three times greater at night.” This is due in part to the lack of natural light, impaired and fatigued drivers, rush hour traffic, and compromised night vision. It is important to take extra caution when driving at night.

The National Safety Council focuses on the following elements that make nighttime driving more dangerous and offer some tips for safety:

Darkness

When it's dark outside, depth perception, color recognition and peripheral vision are compromised. And the glare of headlights from an oncoming vehicle can literally blind a driver temporarily. Even with high-beam headlights on, visibility is limited to about 500 feet (250 feet for normal headlights) creating less time to react to something in the road – especially when driving at higher speeds.

What should you do to combat darkness?

  • Aim your headlights correctly, and make sure they're clean
  • Dim your dashboard
  • Look away from oncoming lights
  • If you wear glasses, make sure they're anti-reflective
  • Clean the windshield to eliminate streaks
  • Slow down to compensate for limited visibility and reduced stopping time

Compromised Night Vision

Night vision is the ability to see well in low-light conditions. As we age, we have greater difficulty seeing at night. A 50-year-old driver may need twice as much light to see as well as a 30-year-old. At age 60 and older, driving can become even more difficult, according to the American Optometric Association. Some older drivers also may have compromised vision due to cataracts and degenerative eye diseases.

The AOA recommends older drivers:

  • Have annual vision exams
  • Reduce speed
  • Take a driving course; even experienced drivers can benefit from a refresher course, and some of the rules have probably changed
  • Minimize distractions at night, like talking with passengers or listening to the radio
  • Check with your doctor about side effects of prescription drugs
  • Be honest about your ability to drive after dark and limit driving to daytime hours if necessary

Rush Hour

Evening rush hour (between 4 and 7 p.m. weekdays) is among the most dangerous time to drive due to crowded roadways and drivers eager to get home after work. During the winter season, it's dark during rush hour, compounding an already dangerous driving situation.

How can you make it home safely during rush hour?

  • Don't be an impatient driver; slow down
  • Stay in your lane and beware of drivers who don't; anxious drivers dart from lane to lane
  • Even though the route may be very familiar, don't go on autopilot; stay alert
  • If you're in an unfamiliar area, consult a map before you go and memorize your route
  • Don't touch your phone, and don't eat, drink or do other things that take your mind off the road

Impaired Drivers

More than 30 people die every day in crashes that involve a driver impaired by alcohol, according to the Centers for Disease Control and Prevention. Add to that drivers impaired by prescription medicines and other drugs, and that number goes up significantly.

The fact is, impaired drivers are most frequently on the road after dark – particularly between the hours of midnight and 3 a.m. on weekends.

And here's a statistic for you: While drunk driving has declined by about one-third since 2007, the number of drivers under the influence of drugs has increased. Between 2013 and 2014, 22 percent of drivers tested positive for a drug that would cause impairment, according to a roadside survey conducted by the National Highway Traffic Safety Administration.

Here's a tip:

  • Just don't drive if you feel impaired

Fatigue

A National Sleep Foundation poll says 60% of adults have driven while they were tired, and another 37%, or 103 million people, have fallen asleep at the wheel.

It gets worse. Of those, 13% say they fall asleep while driving at least once a month, and 4% say they have caused a crash by falling asleep while driving. The reasons are many – shift work, lack of quality sleep, long work hours, sleep disorders – and it doesn't only happen on lengthy trips.

These staggering numbers are backed up by a report by NHTSA that 100,000 police-reported crashes are a result of driver fatigue. Most crashes or near-misses happen at the times you would expect drivers to be tired: 4 to 6 a.m., midnight to 2 a.m. and 2 to 4 p.m., according to NSF.

What can you do? The Transport Accident Commission offers this advice:

  • Get a good night's sleep
  • Take regular breaks every two hours
  • Share the drive
  • Pull over and take a nap if you're drowsy
  • Be alert for other drowsy drivers on the road

Stay Alert, Stay Alive

While we do only one quarter of our driving at night, 50 percent of traffic deaths happen at night. It doesn't matter whether the road is familiar or not, driving at night is always more dangerous.

Make it a safe day!
