A driver suspected of being drunk hit a city public works truck on a busy St. Paul street early Sunday. The crash injured two people, authorities said.

The accident occurred about 2:15 a.m. on Rice Street near Wheelock Parkway, according to police and emergency dispatch audio.

The truck was parked facing north on Rice, with its flashers and yellow roof light illuminated, while its driver was outside picking up trash and a co-worker waited in the cab, said police spokesman Steve Linders.

The other vehicle was heading south and hit the truck head-on, Linders said.

One passenger in each vehicle suffered minor injuries, and they were taken from the scene by emergency medical personnel.

The driver of the private vehicle, 45-year-old Antonio L. Smith of St. Paul, was arrested on suspicion of driving while intoxicated.

Smith was being held Sunday afternoon on suspicion of felony criminal vehicular operation, according to jail records.
