The driver of a car that plowed into four people late Thursday in northeast Dallas was not drunk, but investigators believe he was going too fast.
Officers were called at about 9:30 p.m. to the accident scene in the 9700 block of Whitehurst Drive.
The four, including a child, were taken to area hospitals, where they were still being treated Friday morning, said Senior Cpl. Kevin Janse, police spokesman.
They had been walking on the sidewalk when they were hit by the 1996 Chrysler Concord, Janse said.
The driver, a 23-year-old man, passed a field sobriety test. Investigators believed that speed contributed to the accident, Janse said.
Janse did not know how fast the car was going.
"There probably were other factors," Janse said, but those won't be released until after investigators complete the report.
A citation for driving without a license was issued to the driver, Janse said.
Two men, ages 23 and 36, were taken to Baylor Medical Center and were listed Thursday night in critical condition.
A 22-year-old woman was taken to Presbyterian Hospital in serious condition. The child, a 4-year-old boy, was taken to Children's Medical Center.
None of their medical conditions were available Friday morning. Janse said their names will not be released before a supervisor reviews the report.
Three people, including a 3-year-old, were in the car during the accident, but they were not hurt, Janse said.
