Te longitudinal acceleration peaks might be greater than the lateral maximums because of more length than width.Hence,legislationhastillnowconcentratedonlyon reducingthelongitudinalsloshrequiringtransversewallsin tankers. But the stability can be more sensitive to lateral sloshing because wheel load transfer and overturning ten• dencycanbemoredominatinglaterallythanlongitudinally [5].Longitudinalsloshinginitselfismoreabruptandeasily perceivable to the driver even if it occurs in the trailer.
