Border crossing info, driving routes, Mexican auto insurance, toll roads, and tips for driving in Baja
You will cross the US-Mexico border heading south. A valid passport, passport card, or SENTRI pass is required for re-entry into the United States.
Crossing southbound into Mexico is usually quick — you drive straight through. The wait is on the return trip northbound back into the US (30 min to 3+ hours depending on time of day and port).
The busiest land border crossing in the Western Hemisphere. Located at the southern terminus of I-5 in San Diego. This is the most direct route if coming from Los Angeles or coastal San Diego.
Less congested alternative east of San Ysidro. Accessed via SR-905 or SR-11. Generally shorter wait times, especially on weekends.
US Customs and Border Protection posts live wait times at bwt.cbp.gov. Northbound waits are longest on Sunday afternoons and holiday weekends. SENTRI lane waits are typically 5–15 minutes vs. 1–3 hours in general lanes.
Your US auto insurance does NOT cover you in Mexico. If you are in an accident without valid Mexican insurance, your vehicle can be impounded and you can be detained. This is not optional.
