Transportation

This bill designates a one-mile segment of Mississippi Highway 550 in Lincoln County (from Caseyville Road westward) as the "Lamar Smith Memorial Highway" for commemorative purposes. The Mississippi Department of Transportation will install and maintain appropriate signage along this highway segment. The bill has no policy or regulatory impact - it solely honors Lamar Smith through a highway designation. It takes effect July 1, 2026, and expires June 30, 2027 (as noted in the text).

SB 2269 extends the repeal date for a requirement that operators of fully autonomous vehicles must submit a law enforcement interaction plan to Mississippi's Department of Public Safety (DPS). The bill maintains the existing rule - requiring plans detailing communication protocols, vehicle removal procedures, mode recognition, and safety information - until July 1, 2029 (previously set to expire earlier). This directly affects companies or individuals operating fully driverless vehicles on Mississippi roads, ensuring the DPS can continue enforcing the plan-submission requirement. The change only extends the existing legal timeline; it does not alter the substance of the plan requirements or introduce new regulations.

SB 2393 designates specific road segments in Chickasaw County as the "Davis Lake Road Scenic Byway," running approximately 12.32 miles from the intersection of MS Highway 15 and County Road 124 eastward to MS Highway 41. The bill formally names this route under Mississippi’s scenic byway program (per Section 65-41-1 et seq.) without creating new policies or funding. It directly affects the designated road corridor and local tourism/road signage, but does not alter road maintenance, traffic rules, or financial obligations. The designation takes effect July 1, 2026.

SB 2266 designates a one-mile segment of U.S. Highway 98 in Greene County, Mississippi (from the Chickasawhay River Bridge northward) as the "Michael Robbins Memorial Highway." The bill requires the Mississippi Department of Transportation to install and maintain commemorative signs along this specific highway segment. This is a symbolic, non-substantive designation with no impact on highway operations, funding, or policy. It directly affects travelers using this segment of Highway 98 by adding a commemorative name to the road signage.

SB 2453 amends Mississippi's window tinting law to allow licensed Mississippi optometrists to diagnose medical conditions that qualify for a tinting exemption, previously limited to physicians. This directly affects residents with light-sensitive conditions (like certain skin diseases) who need medical exemptions to legally use darker window tint. The bill expands the list of qualifying professionals who can certify these exemptions but maintains existing requirements: applicants must still obtain a free certificate from county tax collectors, provide a signed diagnosis from a qualified provider, and display the certificate on their vehicle dashboard. It does not change the exemption rules or light transmittance standards for tinted windows.
