Roundabouts

When you are supposed to go straight ahead (for example), sometimes the left lane only goes left, but you're told to go in the left lane if exit 1 or 2. But the arrows on the ground aren't normally until the very front. If there any way to check before??

If you are wanting to check a specific roundabout before you get in the car, you could use google maps’ street view.

Or, while driving, use a satnav/navigation app, and pay attention to road signs - these should help indicate which lane to be in.

Generally though, when approaching an unfamiliar roundabout, slow down, that way you’ll have time to react to the road layout, changing lanes if necessary. If, for whatever reason, you are unable to change lanes, stay in lane and find another route - this is always the safest option.
