The present study investigates the dynamic characteristics of a heavy ground vehicle that is subjected to crosswind on winter roads by two-way coupled simulations of aerodynamics and vehicle dynamics.

Results show that the lateral displacements of the vehicle on the icy road are 13%, 20% and 26% more than the corresponding lateral displacements of the vehicle on the dry road at maximum crosswind velocities of w c w , m a x \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$_{cw,max}$$\end{document} = 3.5 m/s, 4.5 m/s and 5.5 m/s, respectively.
