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

HB 436 increases Mississippi's speed limits on state highways to 70 mph (from 65 mph) and on interstate highways to 75 mph (from 70 mph), effective July 1, 2026. The bill directly affects all drivers using these roads by raising the legal maximum speeds. Key provisions include amending Section 63-3-501 of the Mississippi Code to set these new limits, with the Mississippi Transportation Commission retaining authority to adjust specific sections within these caps. The change applies broadly to public highways without targeting specific vehicle types or user groups.
