With summer vacation season under way, Clark wants to brief you on new passport rules that could create some snafus for unsuspecting travelers.

You'll now need a traditional passport or the new passport card to travel -- even if you're only going to Canada or Mexico by car, rail or airplane.

The feds are so worried about the lack of info concerning the new rules that they've already announced they will permit readmission for confused U.S. citizens. But you can expect to be detained for an undetermined period of time if you don't have your passport identification.

So should you get the newfangled passport card or the traditional passport? Clark recommends the latter. More details about both options are available at State.gov.

Meanwhile, many states are experimenting with new facial recognition software for ID pictures. However, the software apparently can't analyze a picture of someone smiling. Virginia, therefore, is the latest state to make it illegal for you to smile when you have your driver's license photo taken, according to The Washington Post.

But you are allowed to crease your lips upward -- as long as there's no evidence of any teeth showing!
