Seat belts, child seats and air bags

Key points

1. Kansas law requires all occupants of passenger vehicles to use safety restraints, and it is a primary violation.

   Source: Handbook p. 16

   “Kansas law requires that all occupants use safety restraints in passenger vehicles. Seatbelt use is now a “Primary Violation” in Kansas as well.”
   Kansas Driving Handbook, Handbook p. 16

2. An officer can stop a vehicle just for an unbelted adult in a front seat or an unrestrained child anywhere in the vehicle.

   Source: Handbook p. 16

   “If a law enforcement officer sees an unrestrained adult in a front seat, or an unrestrained child anywhere in the vehicle, then that vehicle can be stopped solely for that violation.”

3. The driver is responsible for restraining children in a passenger car, which means a vehicle built to carry fewer than 10 passengers.

   “A “passenger car” is any vehicle designed to carry fewer than 10 passengers.”

4. Children under 4 must ride in a federally approved child safety seat.

   “All children under the age of 4 must be restrained in a federally approved child safety seat.”

5. Children 4 to 8 need a child safety seat or booster seat unless taller than 4 feet 9 inches or heavier than 80 pounds, who then use a seat belt.

   “All children 4 to 8 years of age must be restrained in a federally approved child safety seat or booster seat unless the child is taller than 4'9” OR weighs more than 80 pounds.”

   “Children 8 years and older must be protected by a seatbelt.”

7. Children 12 and under should sit in the rear seat to avoid air bag injuries.

   Source: Handbook p. 28

   “Children age 12 and under should sit in the rear seat of the vehicle to avoid injury from an air bag in the event of a crash.”
   Kansas Driving Handbook, Handbook p. 28

8. Sit so at least 10 inches separate the center of your chest from the center of the steering wheel.

   Source: Handbook p. 28

   “you should adjust your seat so at least 10 inches is between the center of your chest and the center of the steering wheel.”
   Kansas Driving Handbook, Handbook p. 28

9. Wear your belt even with air bags; air bags do not protect you in side, rear or rollover crashes.

   Source: Handbook p. 27

   “While air bags are good protection against hitting the steering wheel, dashboard, or windshield, they do not protect you if you are hit from the side or rear or if the vehicle rolls over.”

Numbers to know

3 questions from the Kansas practice test

1. 1. When may a Kansas officer stop a passenger vehicle solely for a seatbelt violation?

   1. Only when the driver is unrestrained
   2. When any adult in a front seat is unrestrained or any child is unrestrained
   3. Only when a child under four is unrestrained
   4. Only after another traffic violation
   Show answer

   When any adult in a front seat is unrestrained or any child is unrestrained. Kansas treats seatbelt use as a primary violation. An officer may stop the vehicle based solely on seeing an unrestrained adult in a front seat or an unrestrained child anywhere in the vehicle. The driver-only choice is too narrow because the rule reaches front-seat adults and children in any seating position. The under-four choice confuses the separate child-seat age rule with the broader stop authority. The choice “Only after another traffic violation” incorrectly adds a prerequisite. When reviewing this rule, picture the two triggers: an unrestrained adult in front, or an unrestrained child anywhere.

2. 2. Which Kansas children must use a federally approved child safety seat?

   1. Any child under age 12
   2. Only children under age 1
   3. All children under age 8
   4. All children under age 4
   Show answer

   All children under age 4. Kansas requires every child under age four to be restrained in a federally approved child safety seat. The under-one choice sets the age cutoff too low. The under-eight choice overlooks the handbook's separate rule for children ages four through eight, who generally use a child safety seat or booster unless they meet the height or weight exception. The under-twelve choice is not the stated boundary. Keep the age bands separate: under four means a federally approved child seat, ages four through eight involve a seat or booster with an exception, and age eight or older requires a seatbelt.

3. 3. When can a Kansas child usually move from a booster seat to the adult safety belt?

   1. At age 5
   2. When the child weighs 30 pounds
   3. Usually at age 8 or when 4 feet 9 inches tall, riding in the back seat
   4. At age 12
   Show answer

   Usually at age 8 or when 4 feet 9 inches tall, riding in the back seat. When children outgrow their booster seats, usually at age 8 or when they are 4 feet 9 inches tall, they can use the adult safety belt in the back seat. Before that the belt crosses the wrong parts of a small body. The handbook points to the vehicle owner's manual and the child restraint directions for more specific guidance, and it keeps children in the back seat even after they graduate from the booster.
