Do demerit points affect your car insurance?

Why do demerit points affect your insurance?

Demerit points affect the cost of your car insurance premium because the more you incur, the more risky the insurer believes you are. This is based on the fact that demerit points are incurred for dangerous driving activities like texting while driving, speeding, aggressive driving and more. Therefore, in the eyes of the insurer, the more demerit points you have, the more likely you are to get into a car accident and make a claim, the more of a risk you are to insure.

How can I find a cheaper quote if I have incurred demerit points?

Our car insurance experts did some research to understand how demerit points affect the cost of your premium. We looked at 5 providers and found that; if the provider does ask about demerit points then it could cost you hundreds of dollars more. On the other hand, some providers don't ask about demerit points at all - so there's no additional cost. See the breakdown below.

How long do demerit points affect your insurance?

Generally, demerit points last for three years from the date of the offence. In some cases, offences from more than three years ago may still apply because it can take time for the relevant state government to be informed of the offence (for example, if a court case is involved). Once expired, offences should be dropped from your driving record and therefore no longer affect any premiums. It's important to always make sure your driving record is up-to-date and correct before applying for auto insurance to avoid incorrect charges.
