The driver of the other car was also injured.
Gebretsadik's lawyer John Miller said outside court it was not careless driving because he had the benefit of the green light.
The case would involve a complex legal argument.
"[It was] extremely distressing that you're charged in this way."
There should have been some discretion exerted when police were looking into the case, Mr Miller said.
The woman supported her partner and did not want the charges to be laid.
"It was just a tragedy.
"The family is suffering a longed-for child," Mr Miller said.
Gebretsadik did not want to comment following his brief appearance at court.
His partner was not in court.
Gebretsadik was remanded on bail for a status hearing next month.
Detective Inspector Paul Basham yesterday said the decision to lay the charges had not been taken lightly.
"Police have undertaken a thorough investigation which has been subjected to an independent legal review.
"While this will be a difficult time for the family, police believe the matter should be put before the court for final determination," he said.
