Variable speed limit signs are popping up across America as state and local governments work to improve traffic conditions on roads and highways. But Indiana is actually removing its variable speed limit signs because of a new state law that took effect on July 1, 2026. However, the variable speed limit system used by INDOT could reduce that limit depending on highway conditions. So even though the new 65 mph limit was in place, drivers could potentially be notified to go under that limit, allegedly contradicting the speed limit change. The variable speed limit system was initially part of a traffic management project in the southeast area of I-465 around Indianapolis.
