Traffic signals are used to control traffic at intersections by guiding and regulating the flow of traffic. Drivers, cyclists, and pedestrians must obey and understand the different traffic signals. Show
Traffic signals can be 3 colors (red, yellow, and green) that are either flashing or steady. We’ll go through all of the different traffic lights, rules, and meanings in this article. If you prefer video, we’ve made a great explainer video on the subject:
Steady Traffic SignalsRed Traffic LightA red light means that you must come to a complete stop and remain stopped until the light turns green. Never run a red traffic light, it’s very dangerous and also illegal. In some states, you are allowed to proceed in certain circumstances. In California for example, there are two exceptions to this rule unless otherwise signed. If safe, you are allowed to:
However, you are never allowed to turn on red if there is a ‘NO TURN ON RED’ sign. Remember that these exceptions do not apply to all states. Make sure to check the specific rules in your state driver’s handbook. Yellow Traffic LightA yellow light indicates that the green light is about to end – you must stop unless unable to safely do so. Treat a yellow light as the beginning of a red light, as opposed to the end of a green light. Green Traffic LightA green light means ‘GO’. Yield to vehicles, cyclists, and pedestrians still in the intersection. Always approach an intersection at a speed that allows you to slow down and stop if the light changes. Flashing Traffic Signals are generally used to warn road users of dangerous intersections. There are only two types of flashing lights:
A Flashing Red LightTreat a red flashing light as a ‘STOP’ sign and apply the right-of-way rules. A Flashing Yellow LightA flashing yellow light tells you to slow down and prepare to stop. It is used to warn drivers of danger ahead (e.g. a school crossing). Yield to any vehicles, cyclists, and pedestrians in the intersection. Traffic Signals with ArrowsArrows are used to help control turning traffic. Red ArrowA red arrow means that youmust not turn in the direction of the arrow. Wait for a green signal or arrow to appear before you turn. Yellow ArrowA yellow arrow indicates that you must stop, unless unable to safely do so (e.g. if in the intersection). Flashing Yellow ArrowA flashing yellow arrow means that you are allowed to turn, but must do so carefully. Oncoming traffic will face a green light and have the right-of-way. Yield to oncoming traffic and pedestrians. Green ArrowA green arrow means ‘GO’. You can make a protected turn in the direction of the arrow – meaning that oncoming vehicles, cyclists, and pedestrians are stopped by red lights. Yield to vehicles, cyclists, and pedestrians still in the intersection. What Do You Do if a Traffic Light Is Not Working?Malfunctioning Traffic LightsTreat an out-of-order traffic light as a 4-Way Stop sign – proceed according to the ‘right-of-way’ rules unless otherwise indicated by an officer or another authorized person. Lane Use Control SignalsThese signals are overhead lane signals used to indicate which lanes that can be used at a specific time.
You will often see these lights on reversible lanes on the highway. A reversible lane may be open in one direction during morning commute, and in the other direction in the afternoon. Don’t drive in a reversible lane unless there’s a green arrow above Where Should You Stop at Traffic Lights?
Can you enter an intersection on a yellow light in California?Observe the right-of-way rules. Solid Yellow–A yellow traffic signal light means “CAUTION.” The red traffic signal light is about to appear. When you see the yellow traffic signal light, stop if you can do so safely. If you cannot stop safely, cross the intersection cautiously.
What happens if you run a yellow light and it turns red Alberta?If the yellow light turns red while you are in the intersection, you may once again, receive a ticket for failing to stop at a yellow light. As before, it is inevitably up to the Police to determine if they feel you had enough time to stop.
When you approach an intersection with a green light you should?GREEN—A green light means GO, but you must first let any vehicles, bicycles, or pedestrians remaining in the intersection get through before you move ahead. You can turn left ONLY if you have enough space to complete the turn before any oncoming vehicle, bicycle, or pedestrian becomes a hazard.
When you approach an intersection with a green traffic light you should quizlet?if there is a green arrow displayed with a red or green light, you have the right of-way and may turn through an intersection, as long as its clear. If there is a green light displayed without an arrow, you may turn through an intersection as long as its clear. You must yield the right of way to all oncoming traffic.
