Probably a 3 year ban and an alcohol awareness course and maybe some community service. There is no way she can plead mitigating circumstances. it also depends on whether she has any previous convictions for DD. My ex had been banned twice (once for a year and once for 3 years) when she was way over the limit (at least 3 times)and hit a parked car. She was suffering from depression at the time (had tried to commit suicide, was on anti depressants etc) and that stopped her going to prison but she got a massive fine, 3 year ban, retest, community service - the works.
