A sign denoting 'Divided highway' indicates that the highway is split into two separate roadways for opposing directions of traffic. This division typically includes a median or barrier separating the two directions, which enhances safety by reducing the likelihood of head-on collisions. Drivers approaching a divided highway should be aware that the road they are entering will have defined lanes for each direction of traffic and that they must adhere to any posted speed limits and rules specific to divided highways.

The other options do not accurately describe what a 'Divided highway' sign indicates. For instance, the sign does not imply that no left turns are permitted, nor does it indicate changes in maximum speed limits or suggest that there are multiple lanes specifically for merging. Instead, the primary focus of the divided highway sign is the division of lanes for traffic moving in opposite directions.
