The family of a 6-year-old Florida girl has filed a lawsuit against Urban Air Trampoline and Adventure Park, alleging that multiple safety procedures were ignored before a fatal go-kart crash in December 2025.
The lawsuit claims Emma Riddle should not have been permitted to drive the go-kart because she did not meet the manufacturer’s age and height requirements. The family alleges that failures by park employees contributed to the crash that claimed her life.
Incident
According to the lawsuit, Emma Riddle was celebrating her older sister’s birthday at Urban Air Trampoline and Adventure Park in Port St. Lucie on Dec. 6.
The family planned to ride the park’s go-karts after learning the regular ride operator had already left for the evening.
The lawsuit alleges another employee decided to reopen the attraction and operate it despite not following the required staffing procedures.
Allegations
The complaint alleges the attraction required two employees to operate safely.
According to the lawsuit, one employee should monitor the track while another verifies that riders meet the manufacturer’s eligibility requirements before allowing them onto the ride.
The family claims those procedures were not followed.
Requirements
The lawsuit states Emma did not meet the manufacturer’s requirements for operating the two-person go-kart.
According to the filing, she was nearly one foot shorter than the required height and 12 years younger than the minimum driving age.
The family also alleges the park displayed inaccurate signage regarding rider eligibility.
| Manufacturer Requirements | Lawsuit Allegation |
|---|---|
| Minimum age required | Emma did not meet it |
| Minimum height required | Emma was nearly one foot too short |
| Two employees to operate ride | Only one employee allegedly operated it |
Crash
According to the lawsuit, Emma’s mother rode in the passenger seat but was unable to properly secure the seat belt around them.
Despite this, the complaint alleges the employee allowed the ride to begin.
The lawsuit further claims operators skipped a recommended introductory period in which drivers become familiar with the vehicle at approximately 3 mph before increasing speed.
Instead, the complaint alleges the go-karts reached speeds of up to 10 mph immediately.
Emma’s go-kart reportedly struck one barrier before colliding with another wall, causing fatal blunt-force injuries.
She was transported to a hospital, where she later died.
Lawsuit
The lawsuit was filed in Broward County Circuit Court by attorneys with Morgan & Morgan.
The family alleges negligence by the park and claims multiple safety protocols, manufacturer recommendations, state laws, and internal operating procedures were ignored.
The lawsuit seeks to hold the company accountable for the events leading to Emma’s death.
Investigation
According to reports cited in the lawsuit, Urban Air agreed to pay $300,000 in fines to the State of Florida related to safety violations connected to the incident.
The settlement does not constitute an admission of liability in the family’s civil lawsuit, which remains pending.
Urban Air had not publicly commented on the lawsuit at the time of reporting.
Outlook
The case will now proceed through the civil court system, where the allegations made by the family will be evaluated.
The claims contained in the lawsuit have not been proven in court, and Urban Air will have an opportunity to respond through the legal process. The case highlights the importance of following ride safety procedures and manufacturer requirements at amusement attractions.
