What type of messages do electronic highway message boards communicate?

Electronic highway message boards primarily communicate safety messages to drivers, which is crucial for maintaining road safety and awareness. These messages can include alerts about accidents, road closures, speed limits, and other critical information that affects a driver's ability to navigate safely.

Safety messages are essential as they help to ensure that drivers are informed about immediate hazards or changes in traffic conditions. By placing this information at strategic points along highways, drivers can make timely decisions that promote safety, such as slowing down, taking alternate routes, or being prepared for unexpected events.

While traffic updates, construction delays, and weather forecasts are also important for drivers, they are typically provided through other channels like radio broadcasts or mobile apps. The primary function of electronic message boards focuses on urgent safety communications, which directly impact drivers' decisions in real-time.
