We propose a description language for formalising the ``Rules of the Road" (e.g., the UK Highway Code). By way of example, we represent the subset of the Highway Code responsible for road junctions and represent these Rules of the Road using linear temporal logic, LTL. Our aim is to ``extract" from this generic representation a set of beliefs, goals and plans that can be used by a BDI agent to augment its universal autonomous vehicle control (e.g., route planning and obstacle avoidance capabilities) with region-specific rules for road use. We intend to target the Gwendolen agent programming language as a prototype for this system, which provides formal verification possibilities.
