Guides

Reference guides to the documents and records that follow a vehicle — emissions test logs, temporary tags, bonded titles, release of liability and the data your car records about itself.

This section is for the parts of owning a car that nobody explains until you need them. A temporary tag expires and you do not know what the second deadline is. A form called a release of liability turns out to be the difference between a clean break and somebody else’s parking tickets. A title arrives marked with a word you have never seen. An emissions test log exists for your vehicle going back years and almost no seller mentions it. Each guide here takes one of those documents or records, sets out what it is for, who issues it, what it proves and where its limits are, and cites the agency that actually governs it. None of it is a substitute for your own state’s published rules, and every guide says so where the answer genuinely varies.
