A driver can anticipate a change in traffic signals by observing the traffic light patterns and the behavior of vehicles ahead. If the light is green for an extended period, it may soon change to yellow, signaling caution. Additionally, the presence of yellow or red light signals from cross traffic can indicate that the driver's light may soon change. Staying alert to road signs and signals also helps in making informed decisions as one approaches an intersection.
Traffic light signals are designed to manage the flow of vehicular and pedestrian traffic at intersections, ensuring safety and efficiency. They use different colors—typically red, yellow, and green—to indicate when vehicles must stop, prepare to stop, or proceed, respectively. By regulating traffic movement, these signals help prevent accidents and reduce congestion, promoting orderly transportation.

Traffic signs can only display one piece of information and they are normally not illuminated. Traffic signs are usually put on posts on the side of the road and tell you to stop, yield, or what the speed limit is. Traffic signals have a series of lights (usually Red, Yellow, and Green), which change to give motorists multiple directions. Traffic signals are usually placed in intersections, and aside from telling drivers to go and stop, can also flash arrow signals to tell drivers in a turning lane when to make a turn.
Traffic signals are typically painted a shade of yellow known as "signal yellow," which is a bright and highly visible hue. This color is specifically chosen for its high visibility and ability to attract attention, ensuring that drivers can easily recognize caution or warning signals. The exact shade may vary slightly by region or country, but it generally adheres to standards set by transportation authorities.
