Why is stopping distance for a tank vehicle potentially longer or less predictable than for a solid-load truck of the same total weight?

Pick an answer

1. Stopping distance is unaffected by whether the cargo is liquid or solid, since brakes respond only to total weight
2. Liquid cargo always shortens stopping distance compared to solid cargo
3. Forward surge during braking can add extra force that continues pushing the vehicle even as the brakes work to slow it
4. It only matters for tanks that are less than half full
