What does a sign with an exclamation mark indicate?

A sign featuring an exclamation mark serves as a warning to drivers, indicating that there may be a potential hazard ahead. This type of sign is used to alert drivers to various situations they might encounter on the road that could require caution, such as sudden changes in road conditions, construction zones, or wildlife crossing.

Recognizing this type of sign helps drivers maintain awareness and adjust their behavior accordingly to ensure safety. Such signs play a crucial role in promoting defensive driving, as they prepare drivers for unexpected situations they may face while traveling.

In contrast, signs indicating speed limit changes, no parking, or school zones typically have specific symbols or wording that clearly define those regulations, rather than general warnings about potential hazards.
