Ramirez suffered hand fractures and was treated at a San Diego hospital.
Goudie said Ramirez will not be held responsible for the deaths based on the evidence gathered so far.
Authorities are still looking for the driver of a gold Honda Accord who allegedly forced Ramirez off the road when attempting to pass a group of motorcycles on Route 98 east of San Diego.
Investigators said around 1 p.m., the driver of the Honda tried to pass about a dozen motorcycles on that two-lane highway.
An oncoming car, driven by Ramirez, had to swerve out of the way, but the driver over-corrected and collided with several motorcycles, killing four riders: two men and two women.
A fifth fatality resulted from injuries sustained by a passenger in Ramirez's vehicle.
The driver at fault never stopped.
The CHP withheld the names of the five who died, pending notification of next of kin.
