Careaga was behind the wheel of his 2009 Mercedes when he collided with Lopez-Ruiz's motorcycle in the 700 block of East Sunrise Blvd. on Sept. 10.
Police say Careaga drifted out of his lane when he hit Lopez-Ruiz, who was thrown from her motorcycle and died at the scene.
Careaga allegedly told officers at the scene he'd had two vodka drinks before the crash.
Lopez-Ruiz, 22, had just earned a spot on the Miami Heat dance team in June.
