If you have been disqualified by a Magistrate or a Judge you are not allowed to drive for the period stated.
If you are caught driving during this period you will likely be charged and the vehicle impounded.
If you are convicted you risk being disqualified for a minimum of 6 months (or a minimum of 12 months if it's your 3rd or more time).
You risk your car being seized and sold by the court. This is actually a mandatory law though clients are rarely told about it. There are loopholes to protect your car from being seized.
In terms of not being disqualified again there are several options:
To be clear you cannot apply for or be granted a limited licence if you are disqualified for driving while disqualified.
I have successfully defended charges of driving while disqualified and saved people's licences using the other legal option available.
