Which type of sign implies the presence of obstacles or dangers on the road?

Warning signs are specifically designed to alert drivers to potential hazards or obstacles on the road. These signs are typically depicted in a yellow or orange color and use symbols or messages to convey the dangers that may lie ahead, such as sharp curves, road work, or animal crossings. The primary purpose of warning signs is to prepare drivers to take caution and reduce their speed in order to navigate safely through areas where hazards are present.

Regulatory signs, on the other hand, provide information on laws and regulations that must be followed, such as speed limits or stop signs. Informative signs offer guidance or information, such as directions to points of interest, but do not necessarily indicate dangers. Parking signs are specifically related to parking regulations and do not convey information about hazards on the road. Therefore, warning signs serve a unique and critical function in alerting drivers to the presence of obstacles or dangers, making them the correct choice in this context.
