A green signal means all movements—straight ahead, left or right turns—are permitted, unless prohibited by a sign. Left turns must first yield to pedestrians and oncoming traffic. Right turns must first yield to pedestrians.

You are allowed to make the following turns on red after coming to a complete stop unless a sign or police officer states otherwise:

This sign may appear below a stop sign. Traffic turning right may turn without stopping. Other traffic must stop and yield right of way.

Be alert for people crossing your path. These signs may include a flashing yellow beacon that indicates a pedestrian is crossing, has recently crossed or is about to cross.

We are now reaching a turning point where AI is becoming a potential source of risk at a scale that should be incorporated into risk and emergency management phases — mitigation or prevention, preparedness, response and recovery.

A flashing yellow arrow means that you may make the movement indicated by the arrow, but first you must yield to pedestrians and oncoming traffic. Oncoming traffic has a steady green signal.

Over the past 20 years, my colleagues and I — along with many other researchers — have been leveraging AI to develop models and applications that can identify, assess, predict, monitor and detect hazards to inform emergency response operations and decision-making.

A steady yellow arrow warns you that the signal is about to turn red. Stop before entering the intersection, or if you cannot stop safely, drive carefully through it.

Governments have also started developing some risk assessment guidelines for the use of AI-based technologies and solutions. However, these guidelines are limited to risks such as algorithmic bias and violation of individual rights.

Safety corridors are designated stretches of highway with more fatal and serious injury collisions than the statewide average. Turn on your lights for safety. Signs identifying safety corridors may include diamond shaped flags.

Warning signs are yellow and alert you to known possible hazards or a change in road conditions ahead. As a driver, you are ultimately responsible for recognizing and reacting correctly to changing conditions, signed or not. Not all warning signs are shown here.

AI technologies are becoming more widely used by institutions, organizations and companies in different sectors, and hazards associated with the AI are starting to emerge.

Many AI experts have already warned against such potential threats. A recent open letter by researchers, scientists and others involved in the development of AI called for a moratorium on its further development.

Intentional AI hazards are potential threats that are caused by using AI to harm people and properties. AI can also be used to gain unlawful benefits by compromising security and safety systems.

AI hazards can be classified into two types: intentional and unintentional. Unintentional hazards are those caused by human errors or technological failures.

In 2018, the accounting firm KPMG developed an “AI Risk and Controls Matrix.” It highlights the risks of using AI by businesses and urges them to recognize these new emerging risks. The report warned that AI technology is advancing very quickly and that risk control measures must be in place before they overwhelm the systems.

Signs often use symbols or pictures rather than words. Each type of sign has a special color and shape to help you easily recognize the sign at a glance.

The lane is reserved for vehicles carrying at least two or more persons as noted on the sign. A white diamond may be painted on the lane.

Traffic signals control the right of way and provide for a smooth, orderly flow of traffic. If a signal appears dark, such as during a power failure, you should stop as if there are stop signs in all directions. When a traffic signal is out of order and flashes yellow or red, you must obey that signal.

For the most part, the focus of contemporary emergency management has been on natural, technological and human-made hazards such as flooding, earthquakes, tornadoes, industrial accidents, extreme weather events and cyber attacks.

A steady yellow signal warns you that the signal is about to turn red. Stop before entering the intersection. If you cannot stop safely, drive carefully through it.

Much of the national level policy focus on AI has been from national security and global competition perspectives — the national security and economic risks of falling behind in the AI technology.

However, with the increase in the availability and capabilities of artificial intelligence, we may soon see emerging public safety hazards related to these technologies that we will need to mitigate and prepare for.

Up until now, AI hazards and risks have not been added into the risk assessment matrices much beyond organizational use of AI applications. The time has come when we should quickly start bringing the potential AI risks into local, national and global risk and emergency management.

In my view, this simple intentional and unintentional classification may not be sufficient in case of AI. Here, we need to add a new class of emerging threats — the possibility of AI overtaking human control and decision-making. This may be triggered intentionally or unintentionally.

While we should collectively and proactively try for such governance mechanisms, we all need to brace for major catastrophic AI’s impacts on our systems and societies.

In its 2017 Global Risk Report, the World Economic Forum highlighted that AI is only one of emerging technologies that can exacerbate global risk. While assessing the risks posed by the AI, the report concluded that, at that time, super-intelligent AI systems remain a theoretical threat.

T intersection sign

Hazards that have low frequency and low consequence or impact are considered low risk and no additional actions are required to manage them. Hazards that have medium consequence and medium frequency are considered medium risk. These risks need to be closely monitored.

The main objective of the directive is to ensure that when AI systems are deployed, risks to clients, federal institutions and Canadian society are reduced. According to this directive, risk assessments must be conducted by each department to make sure that appropriate safeguards are in place in accordance with the Policy on Government Security.

You must obey all official signs, signals, and markings unless you see a police officer or road worker redirecting traffic.

Traffic signs that prohibit certain actions or movements are red in color and increase safety by controlling the flow of traffic through intersections.

Advises the safe speed for freeway ramps and curves. This sign may be used with other signs. Signs may be electronic and may change based on current conditions.

The signs below prohibit certain actions. When you see a sign with a red circle and a slash mark, it means do not make the turn shown.

Intersection Ahead sign

These blue signs tell you about services or facilities along the highway. These signs may indicate gas, food, and lodging are available at the next exit, a rest area is ahead, an electric vehicle charging station is available or a facility or parking area is accessible to a person with a disability. They can also indicate the road to a hospital.

At the government level, the Canadian government issued the “Directive on Automated Decision-Making” to ensure that federal institutions minimize the risks associated with the AI systems and create appropriate governance mechanisms.

Public safety and emergency management experts use risk matrices to assess and compare risks. Using this method, hazards are qualitatively or quantitatively assessed based on their frequency and consequence, and their impacts are classified as low, medium or high.

As the use of AI increases, there will be more adverse events caused by human error in AI models or technological failures in AI based technologies. These events can occur in all kinds of industries including transportation (like drones, trains or self-driving cars), electricity, oil and gas, finance and banking, agriculture, health and mining.

However, the latest Global Risk Report 2023 does not even mention the AI and AI associated risks which means that the leaders of the global companies that provide inputs to the global risk report had not viewed the AI as an immediate risk.

Hazards with high frequency or high consequence or high in both consequence and frequency are classified as high risks. These risks need to be reduced by taking additional risk reduction and mitigation measures. Failure to take immediate and proper action may result in sever human and property losses.

The U.S. National Security Commission on Artificial Intelligence highlighted national security risks associated with AI. These were not from the public threats of the technology itself, but from losing out in the global competition for AI development in other countries, including China.

This sign means you must come to a complete stop. Yield to other vehicles and stop and stay stopped for pedestrians crossing in marked or unmarked crosswalks. When it is safe, you may enter the intersection.

In 2021, the U.S. Congress tasked the National Institute of Standards and Technology with developing an AI risk management framework for the Department of Defense. The proposed voluntary AI risk assessment framework recommends banning the use of AI systems that present unacceptable risks.

AI development is progressing much faster than government and corporate policies in understanding, foreseeing and managing the risks. The current global conditions, combined with market competition for AI technologies, make it difficult to think of an opportunity for governments to pause and develop risk governance mechanisms.

A steady red arrow means stop and remain stopped until the signal changes, except for allowed turns on red. The same turns allowed for a steady red signal are allowed for a red arrow.

Regulatory signs are rectangular with black words or symbols on a white background and tell you what to do. They are posted at or near where the requirement applies. Not all regulatory signs are shown here.
