Before you set out, it helps to know the lingo. Use the Los Angeles driving guide to find out what a SigAlert is, rules for Los Angeles carpool lanes and to see an LA freeway map.
I-5 north is the most common way to get from San Diego to Los Angeles, passing along the coast with brief glimpses of the Pacific Ocean, through Camp Pendleton Marine Corps base and north through Orange County.
The directions are simple: just get onto I-5 and drive north, branching off onto I-405 if you're headed toward Irvine, Long Beach, the South Bay beach cities or LAX. Stay on I-5 to get to downtown LA.
The I-5 immigration checkpoint is located 7 miles south of the town of San Clemente, just north of Camp Pendleton.
I-15 north is the alternative route for your drive from San Diego to Los Angeles. It adds 20 minutes to the trip if there are no traffic jams, but it may have lighter traffic than I-5.
Check the traffic before you set out to determine the best route. If you don't have a mobile device that provides traffic info, Los Angeles radio station KNX 1070 has frequent updates.
Leave San Diego on I-15 north, then follow CA Hwy 60 west. You'll need a map or online directions to find how to reach your specific destination.
The I-15 immigration checkpoint is located between Escondido and Temecula.
