While there isn’t a waiting period, you do want to be sure you sign all of your policy documents. If you purchased your insurance policy online, most companies send you all of your policy documents electronically. You will need to e-sign the documents to ensure you maintain coverage.
If you still feel unsure about coverage, you can always speak directly with an agent at your car insurance company. They will be able to confirm all of your policy details and when your coverage is effective.
Congrats again, and enjoy the open road!”
