What does a player need to do immediately if their ball is out of bounds and it hit a maintenance vehicle?

In the situation where a player's ball goes out of bounds after hitting a maintenance vehicle, the player must follow the appropriate procedures outlined in the rules of golf. The correct action is to take a two-stroke penalty and continue play from the correct spot.

When a ball is determined to be out of bounds, it is essential to understand that the player cannot continue play from that spot. Instead, they must go back to the original spot where they played the last stroke and hit again, which incurs the penalty.

This action reflects how the rules deal with the dual factors of hitting an out-of-bounds ball and the intervention of an unplayable situation (such as hitting a maintenance vehicle). The penalties and rules are designed to ensure fair play and maintain the integrity of the game, allowing players to move forward correctly without further confusion.

The other options would not be appropriate responses according to the rules of golf regarding out-of-bounds situations.
