# Addon Vehicles * If you haven't registered your addon vehicles in the client memory using the native **AddTextEntry** you will need to go to **`av_laptop/client/editable/vehicle_names.lua`** and follow the instructions to register all your **addon vehicles.** * **Why register addon vehicles?** If you skip this step, vehicles will show up as "NULL" on the leaderboards. This occurs because FiveM does not natively know the real name of an addon car, so you must define it manually for the script to recognize it. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
