Rule 300: Tram-only routes
You MUST NOT enter a road, lane or other route reserved for trams. Take extra care where trams run along the road. You should avoid driving directly on top of the rails and should take care where trams leave the main carriageway to enter the reserved route, to ensure you do not follow them. The width taken up by trams is often shown by tram lanes marked by white lines, yellow dots or by a different type of road surface. Diamond-shaped signs and white light signals give instructions to tram drivers only.
