The damage done by this particular truck doesn't seem astonishingly high, compared with what such trucks might do in other circumstances. I don't know how much a section of bridge costs, but the truck knocked out two or three sections of fairly ordinary elevated highway. I would think that a truck that exploded near a suburban shopping mall gas station would do a lot more damage, and that trucking companies would have to be covered for that.
In a large city which will remain nameless there is a major highway that crosses a lake via a long floating bridge. On both ends of the bridge are tunnels. Sometimes on adjacent highways there are illuminated signs that say gasoline trucks may not take the short cut across the lake. But the signs are only displayed a small percentage of the time. These times don’t seem to relate directly to traffic. It would seen prudent to prevent the trucks from crossing the lake altogether, although it would mean a lot of longer trips. I haven’t figured out the logic of this.
