It is, following a truck helps the rear areo. The best bet is for everyone to draft in a big long line on the highway, like Talladega.

Read this study: http://gcep.stanford.edu/pdfs/ChEHeX...0_11_trans.pdf

Conclusion: it helps both the leading and the following vehicle.

[R.I.D.E.]

If you are in the low pressure area behind the vehicle you are drafting, you are reducing the total volume of the low pressure area, which decreases the effects on the leading vehicle.
