What is prohibited in JSO vehicles regarding seatbelts?

• A. The use of seatbelt extenders
• B. The use of seatbelts
• C. The use of seatbelts by passengers only
• D. The use of child restraints

Answer: (A)

In JSO vehicles, the use of seatbelt extenders is prohibited. Proper belt fit is essential for the restraint system to work correctly, including how the belt locks during sudden stops and how airbags deploy. An extender can alter the belt’s path, add extra slack, and prevent it from securing the wearer as intended, increasing injury risk in a crash. If someone cannot fit into a standard belt, the right course is to arrange alternative transportation or accommodations rather than using an extender. Wearing the belt without an extender keeps the system functioning as designed and maintains safety for all occupants.
