¡Bajan! The One Word That Gets You Off a Mexico City Pesero

I got on somewhere near Insurgentes and watched my street go past the window. Then the next one. Then a street I had never heard of, in a colonia I could not name.

Everyone else was getting off fine. They were saying something short as they stood up, one syllable and a slammed door, and I could not catch it.

So I rode that pesero about twenty extra minutes out of pure vocabulary failure, then walked back.

The word was bajan. That is how you get off a pesero in Mexico City. No bell, no button, no announcement. There is you, your voice, and a driver who is already back up to speed.

The little buses are the last piece of CDMX transport most foreigners avoid, and the only one that goes almost everywhere. Five sentences and you are in.

Pesero, micro, combi, vagoneta: same idea, different metal

They are all the same service - small buses run by private concessionaires on fixed routes - in different vehicles. People use the names loosely and nobody will correct you.

The nickname is a fossil. It comes from the collective taxis of the 1960s that charged exactly one peso per passenger, and it survived every vehicle and every fare increase since.¹ Mexican dictionaries now list pesero as its own word for this kind of transport.²

The general dictionary is drier about it: a microbús is simply a bus smaller than the usual one,³ and a combi is a van whose inside is divided between seats and cargo space.⁴ Both definitions are technically correct and emotionally incomplete.

The windshield is the route map

Peseros do not really have route numbers you can look up on a sign. What they have is a card in the windshield, or paint on the glass, listing the destination plus a few landmarks along the way: a metro station, a big avenue, a market, a hospital.

You read it in about two seconds while the bus is moving toward you. This is a skill. It arrives faster than you think.

The city does publish the concessioned routes as open data, which is genuinely useful for planning at home.⁵ On the street, though, the windshield wins.

To stop one, stand at the curb and put your arm straight out toward the street. Not a wave. Not a polite little hand at chest height. An arm.

They stop almost anywhere along the route, which is the best thing about them and also why traffic in CDMX moves the way it does.

If the windshield is ambiguous, ask through the door before you commit:

• ¿Va por Doctor Vértiz?
  Do you go along Doctor Vértiz?
• ¿Pasa por el metro Chilpancingo?
  Does it pass by Chilpancingo metro?
• ¿Me deja en Álvaro Obregón?
  Can you drop me at Álvaro Obregón?

One street name, one question. The driver answers with a nod, a sí, or a va, and you get on or you step back.

Paying, and the coins that travel over shoulders

Cash, handed to the driver, normally as you board. Carry coins. That is still how most of these units work, and trying to break a 500-peso note on a pesero is a social event nobody wants.

There is an exception worth knowing about. Mexico City has been putting the Tarjeta de Movilidad Integrada, the same card you use on the Metro, onto modernized concessioned units, starting with the hallway buses in 2022.⁶ Those have a card validator mounted next to the driver. Older microbuses and combis do not, and they are still the majority. Glance at the dashboard as you board: a validator means you can tap, no validator means coins.

Fares are distance-based and published. As of 2026 the authorized tariff on a microbús or combi is 7.50 pesos for trips up to 5 km and 9 pesos up to 12 km.⁷ It gets adjusted every few years, so check the current authorized tariff with SEMOVI before you rely on the number.⁸ Fare changes for these routes are a regular news story in CDMX, and they do not move in step with the Metro or Metrobús.⁹

• ¿Cuánto es hasta Coyoacán?
  How much is it to Coyoacán?
• Dos, por favor.
  Two, please.
• ¿Tiene cambio de cincuenta?
  Do you have change for fifty?

Now the part that surprises people. If you board while the bus is full and end up standing at the back, or if someone gets on after you and cannot reach the front, the money travels forward hand to hand over strangers’ shoulders.

Someone will tap you and put coins in your palm. You are not being robbed and you are not being tipped. You are a link in the chain. Turn around and pass it to the next person.

The useful phrases are tiny:

Nobody says thank you very loudly. It is a routine, not a favor. A short sale and a nod is the whole exchange.

¡Bajan! The word that opens the door

Here is the core of it. Peseros do not announce stops. There are no screens, no recorded voice, no bell, no strip to pull.

You watch the window. When your corner is one block away, you say it.

• ¡Bajan!
  Someone's getting off!
• ¡Baja!
  Getting off!
• En la esquina, por favor.
  At the corner, please.
• Aquí está bien, gracias.
  Here is fine, thanks.

Grammatically bajan is just the verb bajar, to go down or get off, in the third person plural.¹⁰ Nobody is parsing it. It functions as a horn.

The volume matters more than the accent. Say it toward the front of the bus, not into your own scarf. If the driver does not hear you, a passenger will repeat it forward, which is the system working exactly as designed.

Where you want to stop is worth one extra word:

That last one is worth practicing. On a packed combi you often have to ask the person blocking the sliding door whether they are getting off too, and then physically climb over a knee or two.

A whole ride in five short lines

Written out, the entire language of a pesero trip is shorter than one paragraph of a textbook dialogue.

• ¿Va por Xola?
  Do you go along Xola?
• Uno, por favor.
  One, please.
• Es de atrás.
  This is from the back.
• ¡Bajan!
  Someone's getting off!
• Gracias, joven.
  Thanks, man.

That is it. That is fluency, for this specific purpose.

Everything you were afraid of - not knowing the route, not knowing the price, not knowing how to escape - is handled by five short lines and a willingness to be slightly loud in public.

Tone, safety, and when to skip it

Keep your Spanish neutral and short in here. A pesero is not the place to try out the slang you learned on the internet, and the driver is working, not hosting.

A few practical things, learned the boring way:

• Hold on before the bus moves. Drivers pull away fast and the aisle is narrow.
• Keep your phone in your pocket, not in your hand near an open window or the door.
• Sit or stand where you can see out. You need the street to know when to shout.
• Stand up one block early. Standing up is itself a signal, and it saves the driver a hard brake.
• At night, or with luggage, or when you are already exhausted, take something else. The pesero rewards attention and you will not always have it to spare.

If someone shouts aguas near the door, move. That is a warning, not a greeting.

And when you do get it right - arm out, one street name, coins forward, ¡bajan! at your corner - nothing happens. No one looks at you. The door opens, you step down, the bus is gone.

That is the whole reward, and after a few weeks in this city it feels like a lot.
