A 47-year-old motorcycle rider was taken to the hospital in critical condition yesterday after the driver of a teal-colored truck cut in front of him on Farrington Highway near Aniani Street in Waipahu, police said.

The driver of the truck — possibly a Ford F-150 with an extended cab — did not offer assistance and fled the scene, police said.

He was driving east on Farrington Highway in the left lane when police said he made an abrupt right turn into the Chevron gas station by Aniani Street, cutting off the motorcycle.

The motorcyclist lost control and crashed. He was not wearing a helmet, police said.
