A teenage rider has been left seriously injured after a violent collision involving an electric dirtbike and a vehicle at one of Naples’ busiest intersections.

The crash happened at Tamiami Trail North and Pelican Bay Boulevard South in Collier County, drawing a major emergency response during peak traffic hours.

Witnesses described a chaotic scene as paramedics treated the teenager at the roadside before rushing them to hospital with serious injuries.

Investigators are now working to establish exactly how the collision unfolded and whether speed, visibility or traffic conditions played a role.

The incident is likely to reignite concerns over the growing number of electric bikes and off-road style vehicles appearing on Florida’s roads — often mixing with fast-moving traffic never designed for them.

Drivers faced lengthy delays as deputies closed parts of the intersection to examine debris and vehicle damage.

No arrests or citations have yet been announced.

Authorities say the investigation remains ongoing.
