Dear student
trucks carrying flammable material have metallic chains connected to their bodies and dragging against the ground. These chains are used to provide a conducting path to charges developed on the body of the truck due to friction of air. This avoids a spark and hence a possible explosion which might have taken place in the absence of chains.
Hope this clarifies your doubt.
