From the conversation Watch out for those bad backroads

Post by @Shewmaker

I do know that Florida invests a lot of money on keeping the left shoulder on its interstates and toll roads in tip top shape because during a hurricane evacuation they permit using the left shoulder. There are these signs which fold up when not in use that are unfolded prior to an evacuation which state this permission. They also clean the shoulders when a hurricane has a likely possibility of making landfall. (I don't know whether the national government provides assistance in this or not.) Just before one crosses into Georgia, there are signs indicating that just prior to the state line, those using the shoulder must merge with the rest of the traffic because Georgia does not provide this.
