Driver, passenger OK after dump truck plunges onto 19th Avenue from I-17 in Phoenix

Authorities say a delivery truck veered off the Interstate 17 freeway in Phoenix and plunged onto the 19th Avenue roadway below.

The driver and passenger were both were able to get out of the crumpled truck on their own during the afternoon hours of Dec. 14 and escaped serious injuries.

The two were taken to a hospital as a precaution, however. Their names weren’t released.

Arizona Department of Public Safety officials say the driver somehow lost control of the truck before it clipped the guardrail, then fell about 20 feet to the street below.

It’s unclear what caused the driver to lose control of the truck and DPS will lead the investigation into what happened.

Traffic was snarled on the freeway above due to debris left on the pavement following the crash.
