Enjoy the road!
This is an excellent comment. But knowing the rules in advance is a good idea sometimes. They're aren't many. In more than a dozen crossings recently even the bad ones can be quite interesting and worthwhile experiences, if you accept things for what they are, not what you expect them to be. However I had a unsuccessful crossing once because I re-entered Guatemala after expiring a previous TVIP (after cancelling correctly, on time) and re-entering without the required stay-away period. I recommend having an understanding of durations and re-entry rules unless you're riding a straight line through. If you're intimidated by how to get this information, as I was, and your Spanish is crappy, as mine is/was, then ask the various people here who 'Godfather' their various jurisdictions. For instance, Guaterider for Guatemala, Salcar for Nicaragua.
