Which sign indicates the default speed limit on most roads where no other limit is shown?

• A. Stop
• B. National speed limit applies
• C. Maximum speed
• D. No entry

Answer: (B)

The sign shows that the national speed limit applies. When you see this sign, you’re following the default speed limit for that road type because there’s no other limit posted. The national speed limit differs by road: it’s 60 mph on a single carriageway outside built‑up areas, and 70 mph on a dual carriageway or motorway. In built‑up areas, a separate lower limit (often 30 mph) applies unless signs say otherwise. The other signs mentioned don’t indicate the default rule: a stop sign means you must stop, a no entry sign blocks the road, and a maximum speed sign sets a specific limit rather than the general default.
