If I get pulled over by police do my passengers have to give their ID's?

Q: If I get pulled over and have a valid drivers license can the officer ask my passengers for their names too? -- JohnA: "That's a really good question and it can get a bit confusing too, so let's say for instance a car is pulled over and the reason is for speeding. The passenger's sitting there, they're not doing anything wrong, you don't have to give up your license or your ID. Now if that passenger happens to have committed a violation like not wearing a seat belt, littering or maybe their obstructing or done an affertive movement that jeopardizes an officer's safety then they'll have to give up their ID. Bottom line is if you're not doing anything wrong you don't have to worry about it." -- Washington State Patrol Trooper Chris Webb
