ORANGE CITY, Fla. -

A Volusia County sheriff's deputy was airlifted to a hospital Thursday morning after crashing into another vehicle.

Deputy Roy Galarza, 28, of DeLand, was injured in the crash, which occurred around 6 a.m. near the intersection of Volusia and Graves avenues in Orange City.

Galarza was taken to Halifax Hospital in stable condition, authorities said.  The other driver was uninjured.

According to the Florida Highway Patrol, Galarza was traveling on Volusia Avenue when a white Chevrolet sport utility vehicle driven by 73-year-old Kenneth Hasenbuhler was headed in the other direction and made a left turn.  Troopers said both vehicles had green lights.

The FHP said the driver of the Chevrolet misjudged how fast the deputy's cruiser was traveling and Galarza struck the Chevrolet.  There was damage to the driver's side of the cruiser.

Galarza suffered head injuries but is expected to recover. 

Hasenbuhler, who was not injured in the crash, was cited for violation of right of way.

About 45 minutes after the crash, and just a couple of blocks away, a 16-year-old boy was hit by a car and killed while walking to school.
