A 30 day tag is issued by the car dealer and is necessary to drive a car off the lot. It is a temporary approval until the vehicle can be registered. Most states don't allow a vehicle to be driven on a roadway without proper registration. After the vehicle has been properly inspected and has met the particular state requirements, the driver can get permanent registration and tags for the vehicle. If you need a temporary tag because of a lost tag or failed inspection you'll need to follow a few simple steps.
Gather the documents you'll need. You are required to show proof of insurance and a valid driver's license. Find out if your state requires an application. You can check your state's website to see if the application can be downloaded.
Complete any necessary paperwork then visit your local county building. You don't need an appointment -- they usually work on a first-come first-serve basis.
Present your documents and pay the required fee.
Attach your tag to the back of your vehicle. Remember to make the necessary repairs to your vehicle or complete the registration process before the 30 days are up.
