In Texas, the age limit for operating a jet ski (or any personal watercraft) without supervision is as follows…

• Operators aged 13 to 17 – A person aged 13 to 17 may legally operate a personal watercraft (PWC) if they have completed a boater education course approved by the Texas Parks and Wildlife Department (TPWD) and possess proof of completion onboard.
• Operators aged 12 and under – A person aged 12 and under is not legally permitted to operate a PWC under any circumstances.

All operators need to comply with Texas boating laws and safety regulations, which are designed to ensure the safe and responsible operation of personal watercraft on Texas waterways. These regulations are in place to protect the safety of operators, passengers, and other individuals using the waterways.
