Cars using an express Ready Lane at the border crossing

If you cross the border more than a couple of times a year, the right lane can save you hours. Two programs speed up your northbound return: Ready Lanes and SENTRI. Here is how they differ and whether they are worth it.

Quick answer: Ready Lanes are free and move faster – you just need an RFID-enabled document (like a passport card). SENTRI is a paid trusted-traveler membership with a background check that gives you access to the fastest dedicated lanes. If you cross often, SENTRI usually pays for itself in time saved.

Ready Lanes

Ready Lanes are special northbound lanes for travelers carrying an RFID-enabled travel document – a US passport card, an enhanced driver’s license, a trusted-traveler card, or certain visas. Because the technology lets officers pull your information as you approach, the lanes move noticeably faster than the general lanes. There is no cost and no application beyond having the right document. For most frequent crossers, getting a passport card and using Ready Lanes is the easy win.

SENTRI

SENTRI is a US Customs and Border Protection trusted-traveler program. You apply, pay a membership fee (for several years), and pass a background check and interview. In return you get access to dedicated SENTRI lanes, which are typically the fastest way back across – often cutting a multi-hour wait down to minutes. SENTRI members can also use Ready Lanes and Global Entry benefits.

Which is worth it for you?

Neither program changes what you need to drive legally in Mexico. You still need Mexican auto insurance and the right documents to cross.
