When driving through highway work zones, it's essential to be aware of potential lane shifts or alternating lane closures. This is a common adjustment necessary for maintaining safety as construction and maintenance activities often require temporary changes to standard traffic patterns. Drivers may encounter unexpected obstacles or changes in how lanes are arranged, which are aimed at protecting both workers and motorists. Being prepared for such scenarios allows drivers to navigate safely and adapt quickly to the dynamic environment of a work zone.

In contrast, increased speed limits typically do not apply in work zones, as the focus is on safety rather than speed. Stopping may not always be prohibited, as there are circumstances where stopping is necessary for safety. Extra traffic lights are also not usually installed in work zones; when traffic control is needed, cones, barriers, and signage are more commonly used instead. Hence, awareness and preparedness for lane changes or closures are critical for safe driving through these areas.
