Vehicle Requirements & Sonoyta Border Inspections

• Expect every vehicle to come to a full stop at the Sonoyta border.
• The Process: Officers may do a quick visual scan, ask where you are staying, or perform a full inspection.
• Declaration: If you have items to declare (large electronics, equipment, or extra alcohol), pull to the left immediately after crossing to avoid heavy fines.
• You must be driving your own vehicle, and registration should be in your name or a family member’s.
• Your vehicle registration can’t expire the same month you’re crossing. Make sure everything is up to date.
• Registration is required for vehicles, trailers, and towed toys — and names on all documents must match your ID.

What NOT to Bring

• Vapes and E-Cigarettes: Strictly banned for import into Mexico.
• Weapons and Ammo: Leave all guns and ammunition behind. Even one stray bullet casing found in your car can result in jail time.
• Drugs: Medical marijuana and CBD are 100% illegal to bring across the border.
• Dog Restrictions: Due to New World screwworm concerns, special paperwork and health screenings may prevent you from crossing the border with your dog. Always check the USDA APHIS Pet Travel portal before leaving. [1, 2]

Smart Border Crossing Tips (Sonoyta-Lukeville)

• Hours: The port operates daily from 6 a.m. to 8 p.m. (watch for occasional extensions—always double-check before heading out) From March through Labor Day there may be extended hours ONLY on Fridays, until 10 p.m.
• Wait times: Northbound traffic can vary. Use Google Maps for real-time Lukeville traffic or official border wait tools. Inspections are usually quick (under 2 minutes), but plan extra time on weekends and holidays.
• Pro tip: Cross early—ideally before 10 a.m.—to avoid longer lines during peak periods.
• What to expect: Stay in your lane and follow instructions. You might be asked a few simple questions at the Mexican gate. In busy times, vehicles could be directed to secondary inspection or x-ray. If asked to exit your vehicle, everyone steps out and stands safely aside.
• Mexico’s Operación Frontera strengthens safety through joint U.S.-Mexico coordination. Most travelers notice only minor added steps.
