Passport needed returning from Canada?

[DontPullMeOver]

Hello,
Does anyone know, for sure, if you need a passport to enter the US driving from Canada? I have checked many websites and all seem to say different things. I know you now need a passport flying from Canada, but what about driving?
Thanks for your help,
DPMO

BIG SEXY was just reading this last week, but for the life of him, can't recall the exact details.

He does believe that the passport requirement does kick in this month. If nothing else, call down to your nearest CBP office, they should be able to give you the most up to date info. That or wait for BIG to return to his office and he can get the info.

This requirement kicks in Tuesday the 23rd. If you wish to return to the States, BY AIR, you will need a passport.

By land, other government-issued ID will be acceptable. This too will change in a year or so.

From the DHS site:

Washington — The U.S. Department of Homeland Security (DHS) and U.S. Department of State are issuing a reminder today that beginning Jan. 23, 2007, citizens of the United States, Canada, Mexico, and Bermuda are required to present a passport to enter the United States when arriving by air from any part of the Western Hemisphere. Since announcing this requirement last November, the departments have been encouraging all travelers to obtain passports before they travel.
The public awareness of the air travel requirement continues to grow and current data shows that 88 percent of affected passengers are already traveling to the United States with passports. Since the week of Thanksgiving 2006, 83 percent of U.S. citizens, 94 percent of Canadians, 88 percent of Mexicans, and 99 percent of Bermudans have arrived at U.S. airports with passports.
The air requirement is part of the departments of State and Homeland Security’s Western Hemisphere Travel Initiative (WHTI). This change in travel document requirements is the result of recommendations made by the 9/11 Commission, which Congress subsequently passed into law in the Intelligence Reform and Terrorism Prevention Act of 2004.
The only acceptable alternative documents to a passport for air travel will be the Merchant Mariner Document (MMD) and the NEXUS Air card. The MMD or “z card” is issued by the U.S. Coast Guard to U.S. Merchant Mariners. The NEXUS Air card is issued to citizens of Canada and the United States, lawful permanent residents of the United States and permanent residents of Canada who meet certain eligibility requirements. The NEXUS Air card will only be accepted when used in conjunction with the NEXUS Air program at certain airports. The MMD card will only be accepted when used on official business by U.S. Citizen Merchant Mariners. All active duty members of the United States Armed Forces will be exempt from the requirement to present a valid passport when entering the United States. Legal Permanent Residents of the U.S. may re-enter on their I-551 Permanent Resident Card.
A separate proposed rule addressing land and sea travel will be published at a later date with specific requirements for travelers entering the United States through land and sea border crossings. As early as Jan.1, 2008, citizens traveling between the United States and Canada, Mexico, Central and South America, the Caribbean, and Bermuda by land or sea may be required to present a valid passport or other documents as determined by the Department of Homeland Security to enter the United States.
