What is the maximum speed limit in Louisiana?

The maximum speed limit in Louisiana is 70 mph. This speed limit applies to interstate highways and certain multi-lane roads where conditions allow for higher speeds, while still ensuring safety for all road users. It's important to note that speed limits can vary based on the type of road—urban areas may have lower limits, and some specific zones, such as school zones or construction areas, will have even lower limits to enhance safety. Therefore, while the general maximum on highways in Louisiana is set at 70 mph, drivers should always be attentive to posted speed limit signs as they indicate the specific limits in those areas.
