What are the Warning Traffic Signs?

Warning signs provide alerts and warning about the road conditions or hazards, or possible traffic situations.

Warning signs are usually diamond-shaped and are yellow with black lettering or symbols.

Below are some of the most common warning signs and their meanings:

school children crossing sign

School Children Crossing Sign
The speed limit when driving within 500 to 1,000 feet of a school while children are present is 25 mph unless otherwise posted. So, when you see a School Children Crossing Sign, slow down to 25 mph or slower, watch for children crossing the street and be prepared to stop.

(There is a confusion around school zone speed limit as to whether you should follow the speed limit of 25 mph when school is not in session or when there are no children present. When you are driving, it is difficult to tell from 1,000 feet if there is a school session or children are present. Even if it is Saturday or Sunday, children may be attending a school event such as a sport competition or can be at a playground nearby. Children do not have a sense of detecting street danger and may run cross the street after a ball or there may be excited to run home. So, it is better to be safe than sorry; slow down to the school zone speed limit near a school zone or a playground when children may be present.)
