PHOENIX (AP) — A motorcyclist has died after being struck by a car travelling 140 mph (225 kph) by a suspected impaired driver on a freeway in Phoenix, authorities said Sunday.

The Arizona Department of Public Safety said the driver of the car was taken into custody. The names of the car driver and motorcyclist weren’t immediately released.

DPS troopers said the car was observed going 140 mph — nearly twice the posted speed limit — on Interstate 10 around 1:30 a.m. Sunday.

After crashing into the motorcycle rider, DPS officials said the car’s driver kept going for another mile before the vehicle caught on fire.

They said the motorcyclist was rushed to a hospital, where he later died.

Arizona Department of Transportation officials say the section of freeway where the crash occurred was closed for eight hours while authorities conducted their investigation.
