Of course, she may have pleaded not guilty to the offence of drink-driving (the only one of those you mention with which she was charged that carries a mandatory disqualification) and may be awaiting trial.
This could take up to three months or so (depending on the trial backlog in the area you live). Until her trial she is free to drive.
She might be denying drink drive allegation so if that's the case it will be listed for trial. Court can't disqualify anyone unless they plead guilty or are found guilty after trial. People tend to deny drink drive allegations for various reasons. She could be saying she started drinking when she went back inside her house after the accident, so police/CPS have to commission an expert to calculate amount of alcohol she could've had in her system when she caused accident. You can check with your local magistrates court to find out what happened at her court appearance.
