If somebody tells you to be careful they are giving you a warning that something dangerous could be just around the corner. This plastic warning post was placed on the road to warn drivers that there was a large unwieldy tree close to the road that could potentially cause an accident. A reckless passerby chose to rip the post from its stand and throw it down on the other side of the road. This person clearly did not see the value in this post, which was warning drivers to be careful – to take care.
