What might block your line of sight while driving?
Your line of sight is the visible path of travel from your vehicle to the target area. This line can be blocked by a curve, the crest of a hill, a wooded area, a large truck, etc.
Do you have to be in line of sight to concentrate on a spell?
You don’t need to be within line of sight or within range to maintain concentration on a spell, unless a spell’s description or other game feature says otherwise. So, you can still concentrate on a spell, even if you or the affected target moves to another plane, unless the spell description specifically says that you can’t.
What happens if you lose concentration on a spell?
Some spells require you to maintain concentration in order to keep their magic active. If you lose concentration, such a spell ends. If a spell must be maintained with concentration, that fact appears in its Duration entry, and the spell specifies how long you can concentrate on it. You can end concentration at any time (no action required).
