Mexico allows driving from age 15, younger than the United States’ minimum of 16, an unusual gap for two neighbouring countries. Both share the same 0.08 g/L drink-drive limit, but Mexico’s motorway cap of 110 km/h actually runs higher than the typical US highway limit of 104 km/h. Both countries drive on the right, so that part of the crossing is automatic.
