Medics were dispatched shortly after 1:30 a.m. to Northwest Ninth Avenue and 17th Street, where they found the crash scene and a vehicle that had caught fire, fire rescue officials said.

The driver of the vehicle was taken to the trauma center at Broward Health Medical Center with injuries described as life-threatening, authorities said.

The motorcyclist was pronounced dead at the scene. Officials have not released the person's name, age or gender, and they have not said what led up to the collision.

The intersection sits in a residential stretch of northwest Fort Lauderdale, a corridor where neighbors and commuters share the road with pedestrians and two-wheeled traffic. The crash adds to a grim tally of serious and fatal collisions on Broward County streets, where advocates have long pressed for safer street design, lower speeds and better lighting at high-risk intersections.

Fire rescue officials did not say whether anyone else was involved or whether the fire spread beyond the vehicle. The investigation into the cause of the crash is ongoing, and authorities have asked anyone with information to come forward.
