In Oregon, you generally cannot leave a car parked on a public road without license plates. It is illegal and will likely result in a ticket and the vehicle being towed. The only exceptions are for a very brief period when you have a valid temporary permit (like a trip permit from the DMV) visibly displayed, or if the vehicle is parked on private property, such as your own driveway.
The law requires all vehicles driven or parked on public highways to be properly registered and display valid plates. An unplated car on the street is considered unregistered. Law enforcement has the authority to cite and impound it as a nuisance or abandoned vehicle.
The risks are significant:
| Scenario | Legality on Public Roads | Key Requirement / Risk |
|---|---|---|
| New Purchase, Driving Home | (temporarily) | Bill of Sale and Title in vehicle. Must go directly to get registration. |
| Parked Overnight on Street | Illegal | Vehicle is subject to citation and impoundment. |
| With Valid Trip Permit | Legal for transit, risky for long-term parking | Permit must be visibly displayed. Not intended for extended parking. |
| Parked on Private Property (e.g., driveway) | Legal | No plates required as it's not on a public roadway. |
The safest approach is to complete your registration and plating immediately. If you must park the car, keep it on your private property until it is fully legal for the road.

Nope, don't do it. I learned this the hard way when I bought a project car. Left it on the street for just one night thinking it'd be fine. Woke up to a ticket on the windshield and the car was already on a tow truck. The cop said it's a huge target for theft and considered abandoned. It cost me over $400 to get it out of the impound lot. Just keep it in your driveway until you get the plates.

Oregon law is clear: a vehicle must be registered and display plates to be on a public highway, which includes any public road. Parking an unplated car on the street violates this. The only way to have an unplated vehicle on the road is with a temporary trip permit from the DMV, and even that is meant for movement, not storage. Otherwise, it's an invitation for a citation and towing at your expense.

Think of it from the city's perspective. An unplated car parked on the street looks abandoned. It can't be easily identified, which is a safety and enforcement issue. That's why they'll tag it and tow it pretty quickly. Your best bet is to move it onto your own property immediately—your driveway or even your lawn is fine. As long as it's off the public road, you're okay until you get the official plates sorted out with the DMV.

If you just bought the car, you have a very short grace period to get it home and to the DMV, but that's for transit, not parking. You need the title and bill of sale with you. Parking it overnight is pushing your luck. The definitive solution is to get a trip permit if you need to drive it, or just keep it on private property. Public roads are a hard no. The financial risk of impound fees simply isn't worth the convenience.
