Speed limits; increase on state highways and interstate highways by five miles per hour.

HB 74 increases Mississippi's speed limits to 70 mph on state highways and 75 mph on interstate highways, effective July 1, 2025. This change directly affects all drivers traveling on state-maintained highways and interstates within Mississippi. The bill amends Mississippi Code Section 63-3-501 to raise the statutory maximums, with the Mississippi Transportation Commission retaining authority to adjust limits on specific road segments within these new caps. Toll roads remain subject to separate rules (max 80 mph) but are not directly affected by this bill.
