FOR THIS POLL, PLEASE ANSWER HOW YOU CHOOSE TO PLAY THE GAME, NOT NECESSARILY WHAT THE RULES AS WRITTEN (RAW) SAY.
The Vehicle Damage rules for a "Crew Shaken" result on page 67 of the rulebook say: "The vehicle may not shoot next turn. Passengers may not shoot from within the vehicle next turn, but are otherwise unaffected."
The Vehicle Damage rules for a "Crew Stunned" result on page 67 of the rulebook say: "The vehicle may not move or shoot next turn. Passengers may not shoot from within the vehicle next turn, but are otherwise unaffected."
QUESTION: If a vehicle without a WS becomes Shaken/Stunned in its own turn (for example, by driving over a minefield), how do you play this situation?
OPTION A. The vehicle may continue to move and shoot THIS turn, but is unable to shoot (Shaken) or move and shoot (Stunned) in its NEXT turn.
OPTION B. The vehicle is only considered Shaken/Stunned THIS turn: it must stop moving immediately (Stunned only), and may not shoot THIS turn (assuming it hasn't already performed those actions yet). It is free to move and shoot in its NEXT turn.
OPTION C. The vehicle is considered Shaken/Stunned THIS turn and its NEXT turn: it must stop moving immediately (Stunned only), and may not shoot THIS turn (assuming it hasn't already performed those actions yet). It also may not shoot (Shaken) or move and shoot (Stunned) in its NEXT turn as well.
OPTION D. The RAW: The Shaken/Stunned result only applies to the NEXT turn, which happens to be the opponent's turn. This means the vehicle essentially suffers no effect (since most vehicles without a WS cannot move or shoot in the opponent's turn anyway).
OPTION E. Something else entirely: reply exactly what it is below.
