Stripped of the formal wording, Rule 273 comes down to one idea: rule 273 (Leaving the motorway (rules 273 to 274)) Unless signs indicate that a lane leads directly off the motorway, you will normally leave the motorway by a slip road on your left. It is advice rather than law, but examiners and the courts still treat it as the expected standard of safe driving.
It belongs to the motorways part of the Code, the habits a confident, considerate driver builds until they are automatic. The aim is not to memorise the sentence word for word, but to understand the hazard it protects you from, so you apply it without having to think when it counts.
If you are learning, treat this rule as one piece of a connected set rather than an isolated fact. The related rules below sit in the same section and reinforce each other, reading them together is how the motorways part of the Code starts to feel like common sense rather than a list to revise.
Because this is advisory rather than legal, no one will fine you for the rule alone, but ignoring it can still count against you in a careless-driving case, and it will cost you faults on the test. Either way, the safe move is to build the habit early, while a driving instructor can correct it, rather than relearning it under test pressure. That is exactly what the practice routes and coaching in the DriveRoutes app are designed to help with, turning the rules below into the way you naturally drive.
High-speed roads leave very little margin for error: a late lane change or a misjudged join at 70 mph develops far faster than the same mistake in town. Building disciplined habits here protects you and everyone travelling at speed nearby.
In the motorways part of the Code, the faults most often written on the marking sheet tend to be the same handful. Knowing them in advance is the quickest way to drive them out of your own habits:
On the day, applying Rule 273 is about doing the safe, deliberate thing slightly earlier than feels necessary: read the situation in good time, observe fully, and act smoothly. The examiner is looking for planned driving, not perfection, and good habits formed in lessons carry you through.
