Not unless you are the last load onto the truck, watch them put your machine where it will be secure and nothing can fall on it in the event of sudden stops or swerves, are the first load off the truck and will be there when the truck is opened to see it come off the truck first.
DD moved 4 hrs. away in July. Her things were loaded on early on a Tuesday morning; arrived late Friday afternoon. Her things did not fill an entire moving truck, so were combined with another job (or possibly more than one, I am not sure). If it's a combined load and you cannot be sure that yours will be last on and first off, with no delays in between (ie, loaded and left in a lot overnight - remember the quilt designer whose van was broken into in a secure lot last fall?), it'll get moved and jostled more than once.
