I'd like to ask regarding DMV payment. What assurance do I have that if I pay, the problem will be resolved?
Your payment does not guarantee that the DMV will restore your registration , or close other suspensions or revocations you have .  It is your responsibility to know if the DMV restored your registration before you drive the vehicle . You can check the status of your driving privilege and vehicle registrations through MyDMV
ok so what can i do
