Tips to Minimize Wait Times
- Cross early morning (2 AM – 6 AM): The fastest window, especially Monday-Thursday
- Avoid Sunday afternoons: Peak return time for weekend travelers — 2-4 hour waits common
- Use the Ready Lane: If you have a Ready Lane-enabled license or EDL, use the dedicated lanes at San Ysidro
- Get Sentri/Global Entry: Dedicated fast lanes can reduce crossing to under 15 minutes
- Try Otay Mesa: Usually 30-45 minutes faster than San Ysidro during peak times
- Check live apps: Use CBP Border Wait Times app or @TijuanaW8 on social media for real-time updates
Insider tip: If you’re crossing back on a Sunday, cross before 11 AM or after 9 PM. The worst window is 2-7 PM Sunday — waits can exceed 3 hours.
What to Do While Waiting in Line
- Keep your documents ready (passport, registration, insurance proof, FMM if applicable)
- Download entertainment — cell service can be spotty approaching the crossing
- Use the time to fill out any customs declaration forms
- Check that your Mexican car insurance policy is active and covers your return date
- Have your vehicle cleaned out — CBP may conduct inspections
Important: Your Mexican car insurance must be active for the entire duration of your trip, including the day you cross back into the US. Check your policy dates here.
