No passing zone sign on a road drivers#
Pentagonal shapes alert drivers to school zone signs and mark route numbers on county highways. Vertically oriented rectangular signs with white and black colors indicate regulatory information, such as speed limits. Octagons with a bright-red background are used exclusively as stop sign shapes, and diamond-shaped road signs mean ‘Warning.’ Red, downward-pointing triangles are only used to tell drivers to ‘Yield’ to other traffic at an intersection or lane merger. A cross-shaped sign is used for railroad crossings. Railroad warning signs are always round, and no other message is conveyed on a round sign except advance warning of a train crossing. Other Road Sign Shapes and Their Meanings This particular shape is not used for any other type of message on the road. The sideways-pointing triangle of a pennant sign on the road tells drivers to stay in their lane and not pass other vehicles. No passing zones are stretches of roadway where drivers are not allowed to move into the adjacent lane to pass a vehicle in front.
The pennant-shape is only used as a road sign to signal a no-passing zone. This publication is the guideline for the design of roadway border edgings, crosswalks, and bike lanes, as well as roadway signs and traffic signal devices, including pennant signs.

The size, shape, color, and symbols used on road signs are regulated through standards published by the federal government in the Manual on Uniform Traffic Control Devices for Streets and Highways. Each of these shapes combines with words, symbols, and background colors to let drivers know information such as maximum speed limits, when to stop or yield, the presence of road hazards and highway facilities, and route markings. Pennant-shaped signs are one of about ten shapes commonly used to communicate with drivers on U.S. Pennant flags bring to mind sporting championships and ship mastheads, but this sideways, tapering triangle-shaped sign is also used for a single purpose on roadways: alerting drivers to stick to the lane they are in and not pass cars ahead.
