Whatever you want. You don't have to answer him, and he can't search you unless he arrests you.

If he's going to arrest you it's probably best not to lie though. You can always say I'm not sure.

If you do have more than $1,000 in cash don't allow him to search your car.

Sorry, but that is bad advice.

Do not talk to the police, ever! If they arrest you, you only ask for the reason of the arrest and for legal counsil (a lawyer) and nothing more!

If they give you a ticket, keep your mouth shut, receive it and present it to a lawyer.

Do not consent to a search, ever! Even if you think you have nothing on you!

The police is not your friend!
