Missouri lawmakers are considering a proposal to raise the speed limit on rural interstates and freeways from 70 to 75 miles per hour. The bill, Senate Bill 1408, would apply to rural portions of the federal interstate system and certain limited-access highways outside urban areas. The proposal aims to amend Missouri law governing speed limits while keeping other statewide limits largely unchanged. If passed, the bill would increase the maximum speed limit on certain highways across the state.
