Prognosis

Not enough signal yet

Not enough signal yet to read this bill's trajectory — we surface a likelihood only once there's real movement (stage, sponsorship, committee, or votes) to point to.

Based on stage, sponsorship breadth, committee status, recorded votes, and cross-state momentum — a description of the observable signals, not a prediction.

In plain language

This bill lowers the legal blood alcohol limit for driving from 0.08 to 0.05.

The bill amends the Illinois Vehicle Code to establish that a blood alcohol concentration of 0.05 or higher is presumed to indicate that a driver is under the influence. Additional changes are also made in related acts.
