🚦 Traffic Signals and Signs: How We Stay Safe on the Road
Summary:
Traffic signals and signs help organize roadways and keep people safe. They tell drivers, bicyclists, and walkers when to stop, go, turn, or slow down. In this article, you’ll learn what traffic signals and signs are, what they mean, and how they help everyone travel safely and smoothly.
🚦 What Are Traffic Signals and Signs?
Traffic signals are the lights at intersections that tell vehicles and people what to do:
- Red = Stop
- Yellow = Slow down
- Green = Go
Traffic signs are metal signs placed along roads that give instructions, warnings, or helpful information.
Together, signals and signs help control traffic flow, prevent accidents, and make sure everyone follows the rules of the road.
🪧 Types of Traffic Signs
There are four main types of road signs. Each has a different color and shape to make it easy to understand.
| Sign Type | What It Does | Example |
|---|---|---|
| 🛑 Regulatory | Tells you what you must or must not do | Stop, Speed Limit, No Entry |
| ⚠️ Warning | Warns of dangers or changes ahead | Curve Ahead, Slippery Road |
| ℹ️ Guide | Gives helpful directions or locations | Exit signs, Hospital ahead |
| 🅿️ Service | Shows services nearby | Gas Station, Parking, Food |
🔴 Traffic Signal Lights: What They Mean
| Light | Color | What to Do |
|---|---|---|
| 🔴 Red | Red | Stop completely before the line or crosswalk |
| 🟡 Yellow | Yellow | Prepare to stop—light is about to turn red |
| 🟢 Green | Green | Go—but only if it’s safe and the way is clear |
Some intersections also have:
- 🚸 Pedestrian signals for walkers ("Walk/Don't Walk")
