Wrong way lights

[Grahamm]

The 'appropriate' lane to go straight over. Is that the left lane or the right lane?.

The illustration shows the left lane being used to go straight over, although this is only a recommendation not mandatory.

You can take the right hand lane if you intend to go straight on and take the right hand lane on the straight-ahead exit (for instance to make progress past other traffic, especially if you're on a bike), but you should do this with great care in case a car from the left lane suddenly turns right without indication etc.
