PHOENIX - Phoenix police say two people are in critical condition after their vehicle crashed on an interstate off-ramp.
Police say a driver and passenger had to be extricated from a Chevy pickup truck after the 4 a.m. crash near 43rd Avenue and the I-10.
Sgt. Steve Martos says the truck was traveling on I-17 and then headed westbound on I-10 at a high speed.
Martos says officers followed the vehicle for a time and then came in contact with it again.
According to police, the truck slammed into the barricade while trying to negotiate a left turn.
Police believe speed was a factor.
Martos says both occupants, believed to be in their late teens or early 20s, suffered severe burns.
Police say the crash area was temporary closed.
