Mexico also has many border control and military and police checkpoints (''retén'') in the middle of the highways throughout the country. These can be great for hitchhiking. It's usually good practice to ask the personnel for permission beforehand, and oftentimes they'll be asking all the drivers where they're going, so they can even let you know if someone's going to your destination.

You can also catch long rides at the exits of the cities when you travel on the highways. Many cities have speed bumps (''tope'') where the highway begins at the edge of town. On smaller highways in more rural areas, there are often speed bumps at every little town, making it easy to move quickly with a number of shorter rides.
