Can gta online players use story mode vehicles in the single player campaign?

Grand Theft Auto Online is described as the online component of Grand Theft Auto V, allowing up to 30 players to explore San Andreas in a multiplayer environment. The source outlines the open‑world nature of both the single‑player and online versions but does not mention any transfer of vehicles or other assets between the two modes. Because the evidence does not include any statement about cross‑compatibility of vehicles, we cannot assert that online vehicles can appear in single‑player. Without additional documentation or official statements, this remains an unverified claim.
