Trying to find the movie title

I am looking for a movie I watched when I was maybe 6 years old (1999), just called back then as the "Trucker movie" had it on VHS :)

Its about a trucker who has to deliver a load of barrels filled with used oil, but has no knowledge of the actual content of the barrels

In the first scene the main character pulls out his truck out of a barn with a small tractor.

There is a scene when a barrel goes loose and slides off on a small hill, thats when they find out what is the content of the barrels.

There is a scene when the two main characters find themselves in a huge wine container in a winery and they almost drown in it.

At the end, the truck jumps into a lake or a river.

The movie end with a future-summary of the characters, like "this guy is still a trucker, has a family" or such.

Any help or tips are welcome.
