Distracted driving is anything that takes your hands off the wheel, your eyes off the road, or your mind off driving — visual, manual or cognitive distraction. Phones are the most common and texting is the most alarming.

Common distractions

  • Talking or texting on a phone
  • Eating and drinking
  • Talking with passengers
  • Putting on makeup or shaving
  • Adjusting the radio, entertainment or navigation system

Minimum time a text takes your eyes off the road — at 55 mph, a football field's length

The toll

  • 3,142 people killed by distracted driving nationally in 2019
  • One in four U.S. crashes is caused by texting and driving
  • Cell phone use leads to 1.6 million crashes a year
  • In Tennessee, a distracted-driving crash happens every 26 minutes, 13 seconds

Tennessee's 2019 hands-free law makes it illegal for a driver to:

  • Hold a phone or mobile device with any part of the body
  • Write, send or read any text-based communication
  • Reach for a device in a way that takes you out of your seated, belted position
  • Watch a video or movie on a device
  • Record or broadcast video on a device
Handbook p. 44 ↗

Know the rule

You may not touch your phone to use GPS. Set your navigation before you drive; to change it, pull into a safe place like a parking lot and stop.

Handbook p. 6 ↗

Know the rule

Texting while the vehicle is moving has been banned since July 1, 2009: a fine up to $50 plus court costs up to $10. On-duty police, firefighters, EMS and emergency management officers are exempt.

Handbook p. 44 ↗

Know the rule

Since January 1, 2018, drivers 18 and older may not use a hand-held phone while moving in a marked school zone with flashers on, unless hands-free. For drivers under 18 there's no hands-free exception — it's a delinquent act.

Handbook p. 44 ↗

Know the rule

It's illegal to install a screen showing TV or video that the driver can see while moving. GPS, vehicle information displays and camera views are allowed.

Handbook p. 44 ↗

Carbon monoxide

A deadly exhaust gas with no taste, smell or color. It can leak in when the heater is on, when the exhaust system is faulty, or from other cars' fumes in heavy traffic.

Handbook p. 43 ↗

Avoid carbon monoxide poisoning

  • Have the exhaust system checked regularly
  • Notice unusual roars from under the car
  • Never run the engine in a closed garage
  • Don't run the heater or A/C in a parked car with windows closed
  • Close the fresh-air vent in congested traffic
Handbook p. 44 ↗

Put it into practice

Your phone buzzes with a text while you're stopped in traffic on the interstate. Leave it. Holding it is illegal, and even reading it at a stop takes your attention off the road. If it's urgent, exit and park somewhere safe first.
