It's hard to say. You might see rates change as you age, but they don't always go down, so much as they level out or increase at a lower rate. (Remember, the rules of inflation are in effect.) And that assumes you don't incur any red marks on your driving record. As for a change in marital status, you generally have to contact your insurer to get a rate decrease — and if your spouse has a less-than-stellar driving record, well, again, you mind wind up paying more.
Companies do not have a standard rule as to what is considered high risk. If you have had an accident or moving violation the variance in premium will differ from company to company. You may have to get several quotes before finding the company that will work with a poor driving record. If you are diligent, then you should be able to find a rate you can live with.
