The MythBusters Take on Drowsy Driving

Asleep at the Wheel

Everyone knows that it’s against the law to drink and drive. But would you believe that getting behind the wheel on insufficient sleep can be just as dangerous?

To test this claim, the MythBusters stayed up for 30 hours and drove two courses– one with plenty of quick stops, turns and parallel parking and the other with 25 laps on a track.

Comparing their sleep deprived drives to those that involved taking several shots of liquor to reach a “buzzed” level, they surprisingly drove 10 times worse when tired than under the influence of alcohol.

According to the CDC, this sounds about right. After 18 hours without sleep, the cognitive ability of drivers compares to a person with a blood alcohol content of 0.05%. Going without sleep for 24 hours sends the equivalent over the legal limit to a level of 0.10%.

This is in no way to say that driving while intoxicated is safe by any means, but merely to demonstrate how hopping into the driver’s seat after little to no sleep can be just, if not more dangerous than being drunk.

More facts about drowsy driving

Based on NHTSA statistics, drowsy driving was responsible for approximately 72,000 accidents, 800 deaths and 44,000 injuries in 2013. Despite these stats, 60% of Americans said they have driven tired and 37% admitted to having fallen asleep at the wheel in the past year.

How to detect drowsy driving

We know you’re busy and have places to go, but if you catch yourself doing any of the following, it’s time to pull over and rest.

Signs you’re too tired to drive:

  • Eyelids droop
  • Mind wanders or you daydream
  • Yawning
  • Drifting into other lanes
  • Inability to focus
  • Difficulty holding head upright
  • Slow reaction time

Who is most at risk?

Those driving alone and/or between the hours of 12am-8am and 1pm-3pm are at a greater risk of falling asleep at the wheel. In fact, in 82% of car accidents caused by drowsiness, the driver was alone.

Shift workers, young male drivers, people with certain medical conditions, and those who don’t get enough sleep are also at higher risk when it comes to drowsy driving.

How to prevent drowsy driving accidents

1. One easy way to stay safe is to get some shut-eye! According to the National Institutes of Health, adults need 7 or 8 hours of sleep a day, and teens need even more at 9 to 10 hours. If you know you haven’t gotten sufficient sleep, then make sure you rest up before you get in the car.
2. The buddy system is another great way to keep your eyes on the road and not behind your eyelids. If you’re going long distances, bring someone along. They can trade off driving or help keep you awake if you find yourself getting sleepy.
3. You might not realize it, but some medications have side effects that can cause drowsiness. Make sure you read the labels before taking anything and getting behind the wheel.
4. Drink some caffeine to give yourself a boost of energy if you think you might be getting sleepy any time soon.

Remember, most auto insurance rates will increase with any accident—no matter who is at fault. In order to keep your premiums down and the road a safer place, take a cat nap or a nice long snooze before you hit the road the next time. That way, your car trips will be a dream instead of a nightmare.
