Why should a driver still perform a physical brake check during the pre-trip inspection even on a bus equipped with ABS?

Pick an answer

1. Physical brake checks are required only on buses without ABS installed
2. ABS assists with wheel lockup prevention, but the fundamental brake system still needs to be confirmed as functioning properly
3. Physical brake checks are unnecessary on any bus equipped with ABS
4. ABS automatically performs all of the necessary brake system checks on its own, so a physical brake check is a waste of time
