Why is clear signage critical in work zones?

Clear signage in work zones plays a vital role in informing drivers of upcoming hazards. In these environments, workers and vehicles may be present in areas that are not normally accessible or visible to the public, which can create unpredictable situations. Effective signage ensures that drivers are aware of potential dangers, such as sudden lane changes, construction equipment, and the presence of workers. This knowledge enables them to take necessary precautions, such as slowing down or changing lanes safely, thereby significantly reducing the risk of accidents.

While reducing the speed of passing vehicles is important and can be a result of effective signage, it is not the primary purpose of signs in a work zone. Similarly, instructions regarding parking availability and information on rest areas are generally not related to the hazards posed by work zones and therefore do not fulfill the main objective of keeping drivers informed about immediate dangers.
