Alberto Velazquez, 21, of Pasco was taken to Kadlec Regional Medical Center Saturday just before noon when his eastbound 1998 Nissan Pathfinder ran off the road while exiting I-182 at 20th Street.
The Washington State Patrol said the car hit a traffic sign, went through the median and vaulted over the eastbound on-ramp. Velazquez was injured when the car overturned, coming to rest on its wheels.
Velazquez, who wore a seat belt, was reported as being treated and released at the hospital. The Nissan was totaled.
