Common child seat mistakes

  • Seat Installation: Make sure the child seat is installed correctly. Follow the manufacturer’s instructions or have it checked for free at a fire station or car seat inspection event.
    • The seat should not move more than an inch when secured.
    • Harness straps should be snug – you should not be able to pinch extra webbing at the shoulder.
    • Strap height:
      • Rear-facing: Straps at or below shoulder level
      • Forward-facing: Straps at or above shoulder level
    • Chest clip should be positioned at armpit level

Leaving Children in Vehicles

  • It is illegal and extremely dangerous to leave a child age 6 or younger unattended in a vehicle without supervision by someone at least 12 years old.
  • Risks include:
    • Heatstroke
    • Car theft/kidnapping
    • Unintended movement if the child shifts gears or plays with controls
  • Even on mild days, interiors heat up fast. Always take young children with you.

Passengers in Truck Beds

  • Illegal to transport passengers in the open bed of a pickup truck unless:
    • It has proper seating and seat belts
  • Exceptions:
    • Parades
    • Certain farming operations
  • Generally, people must be seated in designated passenger areas.

Seat Belt Exemptions

  • Very few exist. Common ones include:
    • Documented medical conditions (must carry documentation)
    • Emergency responders while on duty
    • Garbage truck workers during low-speed operations
  • For 99.9% of drivers, seat belts are mandatory.

Final Reminder

Wearing a seat belt on every trip, no matter how short, is the single most effective way to protect yourself in a crash.

Modern vehicles are designed with:

  • Crumple zones
  • Airbags

But these only work with seat belts. Even if you’re a great driver, you can’t control others — so buckle up and secure all passengers every time.
