Fill in the blank with the most appropriate word:

The car driver was arrested for rash driving and his license was __________ by the police.

The word "impounded" refers to the action of taking something into legal custody, often by authorities, due to a violation or legal reason. In the context of the sentence:

"The car driver was arrested for rash driving and his license was impounded by the police."

However, "impounded" is typically used for physical objects (like a car) rather than abstract things (like a driver's license).
