LAS VEGAS (KLAS) – A motorcyclist was critically injured following a high-speed crash near Las Vegas Boulevard in the south valley, police said.

It happened on Wednesday, shortly before 2:30 p.m. at the intersection of East Windmill Lane and Giles Street.

Evidence at the scene, witness statements, and dash camera footage indicated that a 2017 KTM dirt bike was traveling eastbound on Windmill Lane, approaching Giles Street in the right travel lane at a “high rate of speed while performing a wheelie,” according to Las Vegas Metropolitan police.

A Chevrolet truck was driving westbound on Windmill Lane and entered the two-way center turn lane. The truck then made a left turn onto Giles Street. The crash occurred when the truck entered the path of travel of the dirt bike.

Police stated that the bike then overturned and the man was “partially thrown” from it.

The 19-year-old male motorcyclist was taken to a hospital with life-threatening injuries, according to police.

The driver of the truck remained at the scene and cooperated with the investigation, according to police.
