Roadworks and street closures

• Give and take — the road is narrowed to one lane with no lights or signs; drivers give way to each other in turn.
• Priority working — one lane, with signs giving one direction the right of way.
• Stop/go boards — a worker at each end turns a board to let each direction through in turn.
• Temporary lights — portable traffic lights control each direction in turn.
• Convoy working — traffic is led through the works in a group behind a works vehicle.
• Contraflow — traffic runs in both directions on one side of the road.
• Road narrowing — the road is narrower through the works but open both ways.
• Lane closure — one lane is shut; the rest of the road runs as normal.
• Road closure — the road is shut through the works; follow the signed diversion.
• Slip road closed / hard shoulder closed — the main road runs; only the slip or shoulder is shut.
• Pavement works — the work is on the pavement; the road itself runs as normal.
• Road restriction — the register's catch-all, used when the exact arrangement isn't recorded.
• Skip, scaffolding, street café, hoarding and the like — a permit to occupy part of the street, not road works. Any traffic arrangement it causes is shown on the same line.

High, medium and low impact are the register's own rating of how much a work disrupts traffic. May affect buses means a service passes within ten metres of the works — a measure of proximity, not a report of delay.

Where no arrangement is registered at all, the work shows under its general type — minor, major, urgent, emergency or repair works — as the register records it.
