The “Green Angels” primary focus is to patrol Mexico’s Federal Highways and help stranded travelers they find on the side of the road. These friendly, trained mobile mechanics are bilingual and are able to provide such roadside services as helping to change a tire or install a new engine belt.
However, much more than the basic services, they can also diagnose and fix many other minor (and sometimes not so minor) mechanical / electrical problems as well.
Using their onboard tools, they can extract a malfunctioning alternator, starter or water pump and drive it to a nearby shop to be rebuilt, often at a fraction of the cost of a new one. And once the part is fixed, they can reinstall it in your vehicle and get you quickly back on the road.

Often in just a few hours at most. If the cause of the breakdown is more serious and they are unable to get you back on the road, they can also provide you with a free tow to the nearest mechinic as well as information on where to eat, stay overnight if necesary and answer any other questions you may have.
Their services are indeed free but of course you are responsible for the costs for any outside repairs performed as well as any required parts used.
If you ever do personally benefit from their friendly help while traveling in Mexico, we strongly recommend you consider giving them a very generous tip after they stop and provide you with their helpful service.

History
The Angeles Verdes is a federally funded program under the direction of the Secretary of Tourism (SECTUR) and was first started back in September of 1960, modeled after the AAA Auto Club across the border to the north.
These friendly, helpful “Angels” drive along all of Mexico’s federal highways 7 days a week (including holidays) and on average cover over 22 million kilometers each year. For over six decades the Angeles verdes have helped millions of stranded travelers get back on the road, saving countless thousands of vacations.
On top of providing help in the case of a mechanical breakdown, each of their vehicles is equipped with radios and they are able to summon additional emergency services if needed. They are even called to duty in cases of local emergencies and natural disasters to assist.
Funding for the Green Angels did see some cutbacks a few years ago in a bnudget crunch and for awhile their presence was a bit more limited. However due to public outcry, their funding has now been increased again with new vehicles being added to their fleet along with the hiring of additional mobile mechanics to help travelers.

They mostly operate only during dayight hours which is another good reason why it’s best to follow our advice to avoid night time driving.
How to Contact the Green Angels
The Green Angels routinely patrol the highways but if you need their services now, call 078 from your phone or contact them via an app on your smartphone.

We broke down between Cataviña and Jesus Maria, overheating on our way to BOLA about 10 years ago. These guys pulled up behind us and pulled some kind of epoxy out of their truck that they smashed in all around the leak on our radiator. They shared a beer with us while we gave time for the epoxy to set and they filled up our radiator with water, hanging around while we fired up the engine and tested to make sure it was holding. They even followed us for about 15 minutes to make sure the seal held before finally turning around to head back to Cataviña. We gave them 60 bucks and a six pack for their help and it was money very well spent. That seal held up to BOLA and all the way back home where we got a new radiator.
You gotta love Baja.
Do you operate in San Jose, Todos Santos, Baja Sur? I am trying to find someone to tow my car from San Jose to Todos Santos. Please let me know if this is something you could do in the next few weeks.
