It is indeed a snapshot, and sadly one of little merrit apart from the fact that it's in focus and with the exception of some blown highlights the exposure is correct.
Now ways to improve the shot.
Firstly if you are going to make the van your subject then it's best to try to get it either side on, head on or 3/4 headon profile.
Drop your shooting position to be lower to the ground and either use a long lens setting or wide open. The key is to experiment using vehicles at home to get used to shooting vehicles in a hurry.
Aperture is fine as the entire vehicle is in focus.
Now for the really important stuff:
A good picture should always tell a story, or invoke an emotional response from a viewer. This shot does not achieve that. The only exception to this rule is snap shots.
Keep on trying, you'll get the hang of it in the end. Good luck.
