Arizona authorities say a driver escaped injury when his car�s windshield was pierced by the trunk of a saguaro cactus during a wreck Wednesday on the outskirts of Tucson.

Pima County sheriff�s Deputy Daniel Jelineo said the black sports car struck the cactus while crossing a median.

The broken-off cactus ended up partially inside the car, with the rest jutting over car�s hood.

Jelineo said deputies detained the driver for further investigation after observing signs and symptoms of impairment.
