Not usually. I have a few of them, between 1.5 gal and 5 gal -- normally for keeping fuel for the generator when a wicked stawm is predicted. I don't generally carry a can in my car as the fumes tend to get nasty, even in one of those EPA containers.

Carried some in my van, never had a problem, unless I spilled some when I refilled or used it (or rather the funnel was still wet)
In the Expedition it does stink up the place....go figure.
