Passing on hills and around blind curves with double yellow lines…OH MY! We drive on the cuotas (toll roads) when possible so we thought the drive south to Oaxaca on 135 from the state of Puebla would be as breezy as it gets driving in Mexico. The two lane road is well paved and the shoulders are wide, but strangely (for us) it is expected to drive on the shoulder so other cars can pass. In theory this could work but this custom gives many drivers a false sense of security because they pass on hills and around blind curves with double yellow lines! Several times I drove up over hills and around curves to find vehicles (sometimes two abreast) headed straight for me in my lane. At 70 miles per hour when there was a bicycle or a pedestrian or a pile of rocks fallen from the cliff on the shoulder that became scary- and what could have been a scenic drive became a white knuckled panic attack. Sadly, the roadsides in Mexico are riddled with memorials where lives have been lost. We’ve unscientifically concluded that our chances of crashing our automobile would probably be greater in Mexico than in the US, but we would more likely be shot in the USA.
