Yes, you can drive across state lines with temporary tags in most cases. Temporary plates are issued to give you time to complete formal registration, and they're generally recognized by other states during that window. That said, "generally" isn't "always," and a few states take a harder look at out-of-state temp tags than others.
If you've just bought a vehicle and need to drive it home across state lines, or you're planning a road trip before your permanent plates arrive, this guide covers exactly what's allowed, what to carry, and where you can run into trouble with interstate travel and temp tags.
Before crossing any state line with a temporary tag, make sure you have these documents on hand. A missing paper can turn a routine traffic stop into a real headache.

Most states honor temporary tags issued by other states as long as they're valid and legible. However, a handful of states, including Texas and California, have had documented issues with fraudulent paper tags in circulation. Officers in those states may scrutinize out-of-state temp tags more carefully. Being prepared with your full paperwork packet makes that stop brief.
Every state requires your temp tag to be visible from the rear of the vehicle. Place it in the rear license plate bracket or flat against the inside of the rear window where it's clearly readable. A folded, torn, or sun-faded tag can trigger a stop even if it's technically valid.
Your insurance card must reference the correct vehicle. If you just bought and insured a new vehicle, confirm with your insurer that the VIN on your card matches the one on your bill of sale. A mismatch is one of the most common problems officers flag during temp tag stops. For vehicles still being titled, pairing solid street-legal registration with proper insurance coverage is the cleanest path forward.
Before a long interstate trip, spend five minutes looking up the temp tag rules for each state you'll pass through. State DMV websites publish this information. The Montana Motor Vehicle Division and other state agencies often clarify whether out-of-state temporary plates are accepted during the registration window. When in doubt, carry more documentation, not less.
If your permanent plates won't arrive before your temp tag expires, request an extension rather than letting it lapse. Many states and registration services offer this. Ride Legal offers a Montana Temporary Tag (Extension) for exactly this situation. Don't wait until the last day to request one.

In most cases, yes. States generally recognize valid out-of-state temp tags issued during a legitimate purchase-and-registration window. Carry your bill of sale and proof of insurance to support the tag if you're stopped. Enforcement varies by state, so being prepared matters more than assuming acceptance.
An expired temp tag is treated the same as no registration in most states, which means a citation or even an impound in some jurisdictions. If you know your trip extends past the expiration, request an extension before you leave. Ride Legal offers tag extension services to keep you covered.
Yes. If your tag is expired, illegible, or improperly displayed, any state can issue a citation. The issuing state doesn't protect you from enforcement in other states. Keep your tag valid, visible, and supported by the right paperwork.
Contact the service that issued your registration. If you registered through a Montana-based service, an extension is typically straightforward to request. Ride Legal offers a dedicated Montana Temporary Tag (Extension) product for this exact situation.
