Trip permits and temporary tags: How to legally drive home a car you just bought
There is a legal gap between buying a car and registering it, and a lot of new owners fall into it. The car is yours, the money is paid, but there are no valid plates on it and the title is not yet in your name. The fix is a temporary trip permit, a short-term operating permit that lets you legally drive an unregistered car for a few days while you get to the DMV. A signed vehicle bill of sale is usually what you show to prove you own the car when you apply for one.
What a trip permit actually is
A trip permit, sometimes called a temporary operating permit or transit permit, is a state-issued document or paper tag that authorizes a specific vehicle to be driven for a short window without full registration. States created them for exactly this situation: a car changing hands, a vehicle being moved, or one being driven to an inspection. It is not a registration and it is not insurance. It is a temporary legal pass so that a car with no current plates can be on the road long enough for the new owner to finish the paperwork. The names and formats differ. Some states issue a paper placard for the window or plate area, others give you a document to carry, and a growing number let you generate one online and print it at home. Whatever the format, the permit is tied to one vehicle by its VIN and cannot be reused on another car.
How long they last
Duration varies by state, but most trip permits run short. Oregon issues a 21-day trip permit for driving an unregistered vehicle. Washington offers a three-day trip permit through the Department of Licensing, and buyers may obtain a limited number per year. California provides temporary operating permits tied to the registration process. The common thread is that these are measured in days, not months. They exist to get you from the seller's driveway to your DMV, not to postpone registration, so plan to complete the transfer well inside the window.
Insurance comes first
Most states require active insurance on the vehicle before they will issue a trip permit, and driving on one without coverage defeats the purpose. Your existing auto policy may extend to a newly purchased car for a short grace period, but do not assume it. Call your insurer, add the car by VIN, and confirm coverage is active before you drive. If anything happens on the road home, the permit makes the trip legal, but only insurance protects you financially. The two work together, and one without the other leaves a serious hole. A grace period, where it exists, often applies only if you already carry a policy on another car, and it may cover the new vehicle only at the same level as your existing coverage. If you are a first-time buyer with no current policy, there is no grace period to lean on, so line up insurance before you go to collect the car.
The danger of the seller's plates
Driving home on the seller's plates is illegal in most states, and it exposes both parties. In nearly all states the plates stay with the seller, not the car, so leaving them on means the car is displaying registration that no longer matches its owner. If you are pulled over, the plates trace to someone who no longer owns the car. If you are in an accident, liability tangles between you and the seller. The clean path is for the seller to remove the plates at the sale and for the buyer to drive on a proper trip permit instead. A handful of states do let plates transfer with the car under specific conditions, but that is the exception, not the rule, and it usually requires the buyer to update the registration immediately. When in doubt, treat the plates as the seller's property and get a permit, which removes any question about whether the car is legal to drive.
How the bill of sale helps
When you apply for a trip permit, the state wants proof you are the legitimate owner of the car you are asking to drive. A completed bill of sale supplies that proof. It shows the seller's and buyer's names, the VIN, the date, and the price, which is exactly what a DMV clerk or online permit system needs to tie the permit to a real transaction. Keep the bill of sale and the permit together in the car during the drive home, so that if you are stopped you can show both the permit and the ownership document behind it.
Where to get one
Trip permits are issued by the state DMV or its equivalent, and many states now offer them online so you can print one before you leave to pick up the car. Others sell them at DMV field offices or through licensed agents. If you are buying out of state, check whether the seller's state or your own issues the permit for the drive, since rules differ. Have the VIN, the bill of sale, and proof of insurance ready, because those three items are what nearly every permit application asks for. If you cannot get a permit before pickup, ask the seller whether they will keep the car until your paperwork clears, or arrange to have it towed or trailered home rather than driving it uninsured and unregistered.
A simple checklist for the drive home
Before you pull away in a car you just bought, run through four items. Confirm insurance is active on the car by VIN. Obtain a valid trip permit from the correct state and keep the printed copy in the car. Have the signed bill of sale and the assigned title with you. Make sure the seller has removed their plates. With those four in place, the drive home is legal and covered, and you can register the car at your own pace inside the permit window rather than risking a ticket or an uninsured loss.

Frequently Asked Questions
Can I drive a car home with no plates after buying it?
Not without authorization. You need a temporary trip or operating permit from the state DMV, which lets you legally drive an unregistered car for a few days until you register it.
How long is a trip permit good for?
It depends on the state. Oregon issues 21-day permits, Washington issues three-day permits, and most others fall in that short range measured in days, not months.
Do I need insurance to get a trip permit?
In most states, yes. Active insurance on the vehicle is required before a permit is issued, and it is what actually protects you financially if something happens on the road.
