Your first job behind the wheel is getting everyone there safely, which takes full attention. At 55 mph a car covers a football field in 3.7 seconds, so there's no time for a "mini" snooze or a glance at your phone.

3.7 seconds

Time to travel the length of a football field at 55 mph

Handbook p. 22 ↗

Know the rule

Drowsy-driving crashes are often serious and happen most often on high-speed rural highways when the driver is alone.

Handbook p. 22 ↗

Warning signs of drowsy driving:

  • You can't remember the last few miles driven
  • You hit a rumble strip or drift from your lane
  • You yawn repeatedly
  • You have difficulty focusing or keeping your eyes open
Handbook p. 22 ↗

Preventing drowsy driving:

  • Get a full night of rest before driving; if you get tired, stop
  • A short nap (15 to 45 minutes) and caffeine help only temporarily
  • Get out of the car at least every 2 hours to stretch and walk briskly
  • Set a limit of 300-400 miles of driving per day
  • Avoid medications that cause drowsiness
Handbook p. 22 ↗

Distracted driving

Any activity that could divert your attention from the primary task of driving.

Handbook p. 22 ↗

Types of distraction:

  • Texting and using a cell phone
  • Eating and drinking
  • Talking to passengers
  • Grooming
  • Reading, including maps; using a navigation system
  • Watching a video; adjusting a radio, CD or MP3 player
Handbook p. 22 ↗

Know the rule

Distracted drivers react more slowly, miss hazards like pedestrians or debris, and often have at least one hand off the wheel.

Handbook p. 22 ↗

NC cell phone laws:

  • No one may use a cell phone for email or texting while driving on a public street, highway or vehicular area
  • Drivers under 18 may not use a cell phone while the vehicle is moving (exception: calling 911 in an emergency)
  • No one may drive a school bus while using a cell phone or other mobile-device technology
Handbook p. 22 ↗

Cell phone safety tips:

  • Use it only if absolutely necessary: emergencies, or contacting a parent, guardian or spouse
  • If you must use it, do so at a safe time and place
  • Ask a passenger to place the call and speak for you
  • Let calls go to voicemail and call back once safely stopped
  • Secure the phone so it doesn't become a projectile in a crash
Handbook p. 23 ↗

Put it into practice

Three hours into a trip you catch yourself drifting onto the rumble strip. Take the next exit, get out and walk around, or take a 15–45 minute nap. Caffeine helps only for a while; the real fix is rest.
