She was convicted of manslaughter in November.
"Locane-Bovenizer's blood-alcohol level was nearly three times the legal limit when the crash occurred in 2010 on a dark two-lane road in Montgomery Township, in central New Jersey," AP reported at the time.
The accident resulted in the death of 60-year-old Helene Seeman.
The actress could have faced five to 10 years in prison for vehicular homicide. She also faced three to five years in prison for assault by an automobile. The second charge was the result of the injuries sustained by the woman's husband in the crash.
The judge lowered the maximum sentence citing the hardship on Locane-Bovenizer's two children, according to Fox.
The actress was billed as Amy Locane when she appeared in 13 episodes of “Melrose Place” as the character Sandy Louise Harling, according to iMDb.com.
In 1995, she was nominated for a Young Artists Award for her portrayal of Alex Marshall in the movie “Blue Sky,” which starred Tommy Lee Jones and Jessica Lange.
