Driving in Mexico is easy once you know the signs. They are in Spanish and the speeds are metric, so a quick primer keeps you confident behind the wheel in Baja.
Speed limits in km/h
Mexican speed limits are in kilometers per hour. Quick conversions: 40 km/h is about 25 mph, 80 km/h is about 50 mph, and 100 km/h is about 62 mph. Highway limits are typically 80 to 110 km/h, dropping sharply in towns. Your speedometer likely shows both – use the inner km/h ring.
Key signs to know
- ALTO – stop.
- CEDA EL PASO – yield.
- TOPE or VIBRADORES – speed bumps ahead (often unmarked and aggressive).
- DESPACIO – slow down.
- NO REBASE – no passing.
- CURVA PELIGROSA – dangerous curve.
- DESVIACION – detour.
Beware the topes
Topes (speed bumps) are the number-one surprise for US drivers. They appear at town entrances, schools, and crossings, and many are tall and poorly marked. Slow down whenever you enter a town and watch for them – hitting one at speed can damage your vehicle.
