Can you stop on a carriageway?

• A. Yes, if you are stuck in traffic
• B. Yes, for a quick rest
• C. No, you must not stop on a carriageway, hard shoulder, slip road or central reservation unless it is an emergency or directed by police
• D. Only if you signal to other drivers

Answer: (C)

Stopping on a carriageway blocks moving traffic and creates a real hazard for other drivers, which is why you’re not allowed to stop there. The rule is that you may only stop on a carriageway, the hard shoulder, a slip road or the central reservation in an emergency or if directed by the police. In practice, if you need to stop, look for a safe place off the carriageway such as a lay-by or refuge, switch on your hazard lights to warn others, and follow police or emergency guidance. If you’re on a motorway, use the hard shoulder only in an emergency and only under police instruction.
