Doubtful, a Traffic Act offence, especially a mid-range, presumably only 6 month suspension, would not affect ones ability to do anything... It hasn't affected anything I do... ****, half of the pollies in Darwin are repeat offenders...
Problem may arise for a repeat offender and that goes for any offence. In this instance, CASA Medical would probably want you to seek counselling, but that's probably as far as it could go.
