Driving in Baja is generally straightforward for US and Canadian visitors — the biggest adjustments are insurance, a few local road habits, and knowing where you legally can and can't take a US-plated car.

Mexican auto insurance is mandatory

Your regular US or Canadian policy usually does not cover you in Mexico, and Mexican law requires liability insurance from a Mexican-licensed insurer. Many US insurance companies and agents can arrange a separate Mexico tourist policy, so call your current provider first—this is often cheaper than buying at the border, but compare coverage and deductibles, not just price. If you need insurance at the last minute, numerous kiosks in San Ysidro sell policies by the day. From southbound I-5, take Exit 1A at Camino de la Plaza—the final US exit before the port of entry—to reach them. Buy your policy before crossing into Mexico.

License, registration & the TIP

• A valid US/Canadian driver's license works throughout Mexico — no Mexican license needed for visitors.
• Driving south of the Baja peninsula's free zone with a foreign-plated vehicle requires a Temporary Import Permit (TIP) — Baja California and Baja California Sur are both in the free zone, so a TIP is not required for most Baja-only trips. If you're continuing to mainland Mexico, apply for the TIP online through Banjercito before you go.
• Carry your passport, FMM (if applicable), registration, and insurance card together — you may be asked for all four at once.

Road conditions & toll roads (cuotas)

The toll highway (Hwy 1D) between Tijuana and Ensenada is well maintained, faster, and considerably safer than the free road (Hwy 1 libre), which has sharper curves and less shoulder — worth the toll, especially at night. Car tolls are about MX$50 per plaza; the complete Tijuana–Ensenada route currently totals about MX$152 across its plazas. Away from toll roads, expect potholes, unmarked speed bumps (topes — slow down approaching any town), and livestock on rural roads, especially at dusk.

Local driving habits to expect

• A left turn signal from the car ahead can mean either "I'm turning left" or "it's clear to pass me" — don't pass without a very clear read on traffic.
• At stop signs and ordinary green lights, a driver turning left must yield to oncoming traffic. Do not assume everyone will follow that rule—pause, make eye contact when possible, and move with the established flow only when the intersection is clearly safe.
• Stop signs may be hidden by trees or placed where they are easy to miss. A stop sign diagonally across the intersection (“kitty-corner”) can be a clue that your approach is controlled too, but it is not proof; slow down and make a full stop whenever visibility or priority is unclear.
• Painted crosswalks, stop bars, pavement words, and even lane lines are far less commonplace than in the United States. Watch for signs, signals, pedestrians, and cross traffic rather than relying on pavement markings.
• On autopistas, especially at night, you may encounter retenes (police checkpoints). Some screen for impaired drivers; others are security checkpoints connected to an active police operation, including searches for wanted suspects. Slow down, follow officers' directions, and keep your license, registration, and insurance accessible.
• Glorietas (traffic circles) give right-of-way to traffic already in the circle — entering traffic yields.
• Fuel is sold in liters, self-serve is uncommon — attendants pump for you; a small tip (10–20 pesos) is customary.

What to do when you're stopped by police

Cash bribe requests during traffic stops are common enough in Baja that drivers should be prepared for them. Bribes are illegal, and Baja Amigo does not “officially” recommend paying one, but unfortunately this is still how some roadside stops are handled. $20–$30 USD is generally considered an “acceptable” amount to resolve the encounter, although an officer may ask for upwards of $100 USD.

1. Pull over somewhere safe, stay calm, keep your hands visible, and do not flee or argue.
2. Keep only a small amount of cash in your wallet and store the rest securely out of sight. If an officer presses for cash, you can say that the small amount in your wallet is all you have available.
3. Another option is to request the official ticket and agree to follow the officer to the courthouse or station to pay the official fine. Sometimes this is a bluff: the officer may prefer to move on and look for another driver rather than spend the time—but only use this approach if you are prepared to follow through.
4. If you feel threatened, prioritize your safety and avoid escalating the encounter. Once safe, call 911 for an emergency or 089 to make an anonymous report.

If you're in an accident

Stay calm, keep documents accessible, and be polite. Do not move the vehicles until police and your insurance adjuster arrive if anyone is hurt or there's a dispute — call your insurer's Mexico hotline first, they'll usually dispatch an adjuster who speaks English. Minor fender-benders with no injuries are often settled on the spot between drivers.
