Some questions about jink

By jack_px, in Dark Heresy Rules Questions

Hi, i been reading the rules for vehicle combat and now i have this questions:

- Can a person with step aside be able to use jink twice in a round?

- Is jink considered an evasion test? is jink affected by inescapable attack?

- How do you rule jink if the character is using a clone field? (page 45 enemies without), could you jink twice?

- Could a driver use dodge if he is attacked using the called shot action?
