AN UNLICENSED teenage father of four who crashed at Naughtons Gap killing his pregnant sister will be in jail for at least two years.
Tyron Timothy Williams, 19, of Coraki previously entered guilty pleas to charges including dangerous driving occasioning death and driving with an illicit drug present in his blood over the March 6, 2013 smash.
In sentencing, District Court Judge Laura Wells said Williams had been drinking alcohol at a Lismore caravan park before driving with his sister and two friends to Coraki, where they continued to drink with family.
When Williams left Coraki with the three passengers he drove to Casino, then he was headed back to Lismore via Naughtons Gap Rd when the crash occurred.
"He was going too fast for the conditions of the road he was driving on," Judge Wells said.
"There was no dispute he was drinking alcohol while he was driving.
"In fact, all of those in the car were drinking alcohol during the journey."
Judge Wells detailed Williams losing control on a right-hand bend and slamming into the guard rail of a bridge before the car rolled.
Taylor Maria Davis, 23, who wasn't wearing a seatbelt, was "ejected through the passenger window and suffered a blunt force injury to her head".
In a psychologist's report, Anna Robilliard wrote "he says he has been a binge drinker since he was 15 years old and he has problems with crystal meth and gambling."
Williams told Ms Robilliard "he did not think about the consequences of drink driving as he'd done it before and not got caught".
Blood tests after the crash detected cannabis in Williams's blood and a mid-range alcohol reading of .96, which expert witness Dr Pearl described as a "significant impairment".
Judge Wells took into account Williams's early plea of guilty and his clear remorse since the smash, describing a "mid-range level of moral blame in this case".
She sentenced Williams to three and a half years jail with a non-parole period of two years.
When Williams was led from the court by Corrective Services officers his father yelled: "Stay strong, son".
