Air bags save lives, but they're designed to work with safety belts, and they pose a severe risk to children. Tennessee also has specific laws about kids in pickup beds and kids left alone in cars — where heat can kill in minutes.

Know the rule

Air bags plus safety belts are the best protection available. An air bag deploys and deflates faster than the blink of an eye; NHTSA credits air bags with saving more than 39,976 lives from 1987 to 2012.

Handbook p. 47 ↗

Air bags and children

  • Children 12 and under are safer in the back seat — 'The Back Is Where It's At'
  • Don't put a child safety seat in front of a passenger air bag
  • Put rear-facing infants in the back seat if there is one
  • If a child must ride up front (as in a pickup), slide the seat all the way back and buckle up
Handbook p. 47 ↗

Air bags and adults

  • Always wear both the lap and shoulder belts
  • Tilt an adjustable wheel down, level or parallel
  • Sit as far back as possible — NHTSA recommends 10 to 12 inches between chest and air bag
Handbook p. 47 ↗

Know the rule

It's illegal for a child under 6 to ride in a pickup bed, and for a child 6 to 12 to ride in one on any state or interstate highway (cities and counties may ban it on local roads too).

Handbook p. 47 ↗

Know the rule

The two exceptions: an organized parade or ceremonial event with the truck going no faster than 20 mph, and agricultural activities.

Handbook p. 47 ↗

Know the rule

It's an offense to knowingly leave a child under 7 in a car on public property or at places like shopping centers or apartment complexes without someone at least 13 watching — if conditions are risky, the engine is running, or the keys are inside.

How fast cars heat up

  • Damage can happen in as little as ten minutes
  • 73° outside: an SUV reaches 100° in 10 minutes and 120° in 30
  • 90° outside: the inside can hit 160° within minutes
  • Heat exhaustion above 90°; heat stroke above 105°
Handbook p. 48 ↗

Know the rule

Depending on the harm, leaving a child in a car can be charged from a Class A misdemeanor (up to 11 months, 29 days and $2,500) to a Class A felony (15 to 60 years and up to $50,000). Abuse of a child 6 or younger is a Class D felony.

Handbook p. 48 ↗

Remember

  • Never leave children alone in a car, even for a quick errand
  • Make sure everyone is out when you unload — don't overlook a sleeping baby
  • Lock the car and keep keys and remotes away from children
  • If a child is locked inside, call 911 and get them out fast
  • See a child or animal alone in a car? Call 911
Handbook p. 48 ↗

Put it into practice

It's 90 degrees and you want to run into the store for two minutes while your toddler naps in the car. Don't. The inside can reach 160 degrees within minutes, and leaving a child under 7 with the keys inside is an offense on its own.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

Children age 12 and under are safest riding:
  1. In the back seat of the vehicle
  2. In the front seat with an air bag
  3. Anywhere, as long as they wear a belt
  4. In the front seat only if the air bag is deactivated

Answer: In the back seat of the vehicle

Children 12 and under are safer in the back seat, regardless of whether the vehicle has a passenger-side air bag.

Handbook p. 47 ↗
