This vibrantly colored triangle holds an ominous warning, an exclamation mark at its center. It is a sign to all drivers to be alert and aware, as they have a steep climb ahead of them. To properly convey the cautionary message, the triangle should be shaded in a bright red color to stand out. The exclamation mark can be colored in orange and yellow, the bright colors representing the jolt of warning it is giving. Above the triangle, small wisps of pale yellow or white circling the triangle could further illustrate the steeper path that lies ahead. A careful reader will understand the symbolism of a triangle—that the climb is very steep—and with the exclamation mark in the middle, they will be reminded to drive carefully.
