Walk It Through: The Stop on the Interstate

Lights and a siren after dark, a passenger told to step out, insurance on a phone, and a question about the trunk.

Flashing lights and a siren come on behind a car on the interstate after dark. The driver was going a little over the limit.

Two things a person in this spot might do. Picking one shows what the law says about it.

A routine speeding stop with no arrest. An OWI investigation, a dog sniff on separate suspicion, and a search on probable cause are not worked through here.

A practice walkthrough, not a prediction of how any real one will go. Legal information, not legal advice.
