The drive into Mexico is usually fast. It is the trip back that tests your patience. Here is what to expect at the border, when the lines are worst, and how to check live wait times before you go.
Southbound vs northbound
Going south into Mexico, there is rarely an inspection line – you usually drive right through (you may be randomly selected for a quick check). Coming back north, every vehicle is inspected by US Customs and Border Protection, which is why northbound waits can be long. Plan your return around the lines, not the drive south.
When the waits are worst
- Sunday afternoons and evenings – weekend travelers all returning at once.
- Friday evenings heading into Mexico can back up southbound, too.
- Holidays in both countries.
- Weekday mornings with commuter traffic at San Ysidro and Otay Mesa.
Crossing back midday on a weekday, or late at night, usually means the shortest northbound wait.
How to check live wait times
US Customs and Border Protection publishes live border wait times for every crossing and lane type on its official Border Wait Times website and free app. Check it before you head back so you can pick the fastest crossing and lane – sometimes Otay Mesa or Tecate is moving much faster than San Ysidro.
How to cut your wait
Ready Lanes and SENTRI can dramatically shorten the northbound wait. We cover both in SENTRI and Ready Lanes: are they worth it?. And before you ever head south, make sure your trip is set up properly with everything you need to cross.

Frequently asked questions
How long is the wait at the San Ysidro border?
Northbound waits to re-enter the US commonly run 1 to 3 hours at peak times, and can be shorter late at night or midweek. Southbound into Mexico is usually only a few minutes. Check the CBP Border Wait Times tool for the live number.
Is there a wait driving into Mexico?
Usually very little. Southbound vehicles typically drive straight through, with occasional random inspections.
How do I check border wait times?
Use the official US Customs and Border Protection (CBP) Border Wait Times website or app, which shows live waits by crossing and lane type.
