Why should you fully cross safety chains (in an X pattern) when connecting a converter dolly, where required?

Pick an answer

1. Chains are never crossed on any coupling in a combination
2. Crossed chains make the connection weaker than parallel chains
3. Crossed chains can help catch and support the tow bar if the primary coupling fails, preventing it from dropping to the road
4. Crossing chains is purely a cosmetic requirement with no real safety function behind it that inspectors only look for out of habit during a routine stop
