Car Accident in the USA: What to Do (MX Plates)

Crashed in the US on Mexican plates: call 911, get the police report, notify Chubb. RC liability pays others up to $30,000/$60,000/$25,000 or $100,000 CSL.

The short version

What to do right after a crash in the US

Crashing in a country where you don't fully know the traffic laws, in your second language, stresses out even experienced drivers. The basic steps are similar to Mexico, but a few details are different — and they matter.

1. Stop and check for injuries

Never leave the scene, even for a minor hit. Leaving before police arrive can count as a "hit-and-run" in many states, with serious legal consequences.

2. Call 911

911 connects you to police, fire, and medical services anywhere in the US. Ask for a police unit even if it looks like a minor hit — the official report protects you with your insurer and the other driver's.

3. Document everything

Use your phone for photos and key details before vehicles are moved or witnesses leave.

4. Call your insurer

Do this before signing any repair estimate or form you don't fully understand.

What to document with your phone

Important

An adjuster can tell you, in Spanish, what your policy covers and what to say — or not say — to the other party. Call before signing anything.

How your RC USA coverage works

This is where many drivers get it wrong: your Mexican policy stops being valid the moment you cross the border, no matter how broad your coverage is back home. The same applies in reverse — a US policy doesn't cover American-plated cars driving in Mexico.

That's why RC USA policies (liability-only) exist for Mexican drivers heading north.

The key fact

RC USA covers your legal liability if you cause injuries or damage to others while driving in the US: medical expenses, repairs to the other vehicle, and legal defense if you're sued. It does not cover damage to your own car.

You can buy it for as little as 1 day or for longer periods, and coverage starts as soon as the policy is issued — no waiting period. Get your RC USA quote online in minutes before you head out.

Timi issues these policies by chat, backed by Chubb, usually in minutes — handy if you're crossing last-minute through Laredo or San Diego.

Mistakes that cost you money

Heading back into Mexico

If you're also bringing a US-plated vehicle south, it needs its own coverage: Mexican liability insurance is required by law, and your US policy won't cover you there either.

Before you go
  • Baja California and parts of Sonora don't require a Temporary Import Permit (TIP) for the vehicle
  • Insurance is required no matter where you drive
  • Check more border details in Timi's guide library

Frequently asked questions

Does my full-coverage Mexican insurance work if I crash in the US?

No. Mexican auto insurance, no matter how comprehensive, stops being valid once you cross the border. You need a US-specific liability policy (RC USA) to be legally covered while driving there.

Do I have to call the police for every accident in the US?

Requirements vary by state, but it's almost always a good idea, even for minor damage. A police report is often the strongest evidence you have when dealing with insurance claims or disputes about fault.

How fast can I get RC USA coverage if I'm crossing today?

Timi issues RC USA policies online via chat, with coverage backed by Chubb, typically in minutes—no need to visit an office. Coverage is available from as little as one day, so you can buy it right before crossing.
