Say you pay CTP of $600 typically. There is question on have your licence suspecnded or demerit points in last 3 years:
a. How much would you expect premium to go up by if you lost say 5 demerit points?
a. How much would you expect premium to go up by if your licence was suspended or on restriced good behaviour condition?
Insurers would probably decline to insure (reinsure) you given if your licence is suspended you are no longer legally allowed to drive the car.
If you are in that kind of situation you'd be best to insure your car in another driver/family members name till suspension is over, e:g Spouse or sibling etc.
