Dispatchers received a report of the crash near the intersection of Blue Diamond Road and Kulka Road at about 1:32 p.m., police said. The motorcyclist was pronounced dead at the scene.

Authorities have not released the rider's identity, age or hometown, and additional details about the circumstances of the collision were not immediately available. It was not clear which direction the vehicles were traveling or what factors may have contributed to the crash.

Police asked drivers to avoid the area while investigators processed the scene, and the intersection remained closed for a period Monday afternoon.

The death adds to a grim tally of traffic fatalities on valley roads. Blue Diamond Road, a major east-west corridor that connects the southwest valley to communities near the Spring Mountains, has seen repeated serious and fatal collisions in recent years as development has pushed farther west and traffic volumes have grown.

Anyone with information about the crash is urged to contact the Las Vegas Metropolitan Police Department. The investigation is ongoing.
