Yes, truck drivers do hit those low bridges. Here is a truck transporting a crane striking a low overpass in Russia, nearly getting the biker behind it killed.
The biker, probably staining the inside of his leathers, skids out on the wet highway and very nearly gets run over by the Audi behind. The driver who videotapes the whole incident (starting at 1:03) pulls over to help, which is more than can be said for the trucker, who speeds off into the distance.
This is just one more example of why Russians all carry dashcams.
