Delaware Driver Education State Practice Test

The "approaching divided highway" sign indicates that drivers should keep to the right as they approach a divided highway. This is important because divided highways feature a physical barrier or median separating traffic moving in opposite directions, which helps to enhance safety by preventing head-on collisions. When drivers see this sign, it advises them to prepare for the layout change, which typically requires staying on the right side of the roadway as they enter the divided highway. This instruction helps ensure smoother traffic flow and maintains order, as drivers should not attempt to pass other vehicles on the left unless on a multi-lane highway. The other options provided do not align with the purpose of the sign. Driving on the left side could lead to unsafe situations since this is not the designated flow of traffic. Preparing to turn left is not relevant to the sign's instruction, as it specifically pertains to managing the transition onto a major roadway, not turning. Lastly, speeding up to merge is not a safe or advisable action when approaching a divided highway; instead, drivers are encouraged to adjust their speed appropriately and merge responsibly while keeping to the right.
