Different levels
Route rules. Last checked 3 Nov 2026.
Bridges, tunnels, flyovers and underpasses put one road above another.
Where two roads cross at different levels there is no junction. You can't turn from one to the other.
Change level only on a slip road that is drawn on the map.
Don't turn inside a tunnel. Drive it from one end to the other.
On our map a bridge has a dark edge and a tunnel has a dashed edge.
3 map questions on this rule, free. The drill opens in our trainer.
