If tickets are left unpaid, you not only face additional fines, but you may have to go to court. If you don’t show up or continue to ignore the fines, you could get additional tickets. Those tickets can be reported to the DMV and show up on your driving record.
When they do, your car insurance company can see this. If they are rerating your policy at renewal, you could see an increase in your insurance. If you don’t want to see an increase in rates, pay for your tickets on time. Not only will you save money, but you’ll avoid any future issues.
