Back to what happened to the bridge.
This is a tricky subject to touch on without sounding....xenophobic or anything but... A lot of companies in California seem to hire a lot of people that are, for lack of a better term, "fresh off the boat" These drivers are given minimal training and told to go deliver loads, if you look up the company that hired that driver, they seem to be rather...fly by night. The driver for example was probably using a car GPS, which won't route you around low weight limit bridges. A truck atlas will list weight limits and tell you what roads can and cannot be driven on by a truck. A car GPS for example would route a truck onto a NY state Parkway, a truck GPS would route you on actual truck routes.
The GPS units have free lifetime updates, and cost 300ish dollars for a garmin. That is a lot to ask on a low paying company driver. The guy probably has an "ELD" that is really just an app on a tablet or a phone, no built-in navigation.
