Planning a road trip south of the border is easier than many drivers fear, but the paperwork matters. If you're taking a foreign-plated vehicle into Mexico beyond the border 'free zones', you'll need a Temporary Import Permit — a TIP — and getting it wrong can cost you serious money.

The basics are simple for most travellers. Tourists and temporary residents can bring their car, motorhome or motorbike into Mexico with a TIP, which allows the vehicle to stay in the country for a defined period. The catch: the vehicle must be driven back out of Mexico before the permit expires. If you overstay, you forfeit your deposit, become ineligible to import another vehicle in future, and risk fines or even having the vehicle seized.

One group is excluded entirely: permanent residents of Mexico cannot use a TIP at all. If you've made the move permanent, you can't simply keep your foreign-plated car running on a temporary permit — a different route is needed.

Insurance is the other non-negotiable. You must show evidence of a valid temporary Mexican insurance policy when applying for the TIP. And even if you stay within the 'free zones' near the border, where no permit is required, adequate insurance is strongly advised. US and Canadian policies generally don't cover you once you cross, so a dedicated Mexico policy covering third-party liability — ideally with legal assistance, medical cover and roadside help — is the sensible option. Some US brokers offer English-language Mexico policies, which saves a lot of confusion if something goes wrong.

It's also worth knowing how accidents are handled locally. If you're involved in a collision in Mexico, the process can differ noticeably from what you'd expect at home, and having a policy that includes legal assistance makes a stressful situation far more manageable. Most road trips in Mexico pass off without incident, but a little preparation before you set off goes a long way.

For holidaymakers, the takeaway is straightforward: if your Mexico trip involves driving beyond the border zone — think Copper Canyon, the Yucatán, or a Pacific coast run — sort your TIP and your insurance before you travel, keep an eye on the permit's expiry date, and make sure exporting the vehicle and cancelling the permit is part of your exit plan. Do that, and driving your own car is one of the most rewarding ways to see the country.
