To the light trails I actually really like the first one, it has issues but I rather like the single lorry going away and the motion blur of the lorry at the end, that's really effective
but I suspect that you've done these wide open, which will cause you to blow your headlights and loose any definition, it also narrows your DoF.
The second one I'm guessing was also done wide open but as there are no headlights that's not so much of an issue, I looks to need some CCW rotation.
In relation to light trails I would suggest giving my guide a read, it's linked in my signature, I'm happy to help with anything light trail related, also in that guide there is a link to the light trails map that I'm a moderator on there maybe some locations on there for you to try out
The third is a little bit too over exposed, again I suspect shooting wide open is where your falling down :shrug: I like the last one, it looks a little over exposed but better than the third again it needs levelling it is in need of a small amount of CCW rotation to my eye
