Federal agents will begin randomly stopping traffic today, looking for illegal immigrants, terrorists and drug or weapon smugglers.
Cars will be stopped at unannounced, rotating checkpoints within Michigan, including metro Detroit. U.S. Border Patrol agents at the checkpoints will ask passengers their citizenship and will have leeway to ask a host of follow-up questions.
The effort is part of President George W. Bush's attempt to increase security along the northern border, said Immigration and Naturalization spokeswoman Karen Kraushaar.
