Why is it useful for a driver to know, in general terms, which roads in their operating area are commonly used or approved for hazmat routing, even before a specific trip is planned?

Pick an answer

1. General familiarity speeds up trip planning and reduces the chance of overlooking a restriction under time pressure
2. Approved hazmat routes never change and require no ongoing awareness
3. This knowledge has no practical value until the exact trip is already underway and a problem actually comes up on the road
4. Only dispatchers, never drivers, need this kind of general route awareness
