Six Levels of ADAS Explained: The Ultimate Guide (2024)

Imagine how convenient it would be to sit and nap while you reach your long-drive destination. Well, we have public transportation or taxis for that! But for those who need to take their own car and reach their destination on their own, then there’s a solution. And that’s called ADAS. But ADAS is not an absolute solution. That means there are levels of ADAS. 

These levels start from Level 0 to Level 5, where each level represents a function ADAS (Advanced Driver Assistance Systems) offers to its users. Here, the users can tune their vehicle from no automation to fully autonomous, ensuring enhanced vehicle safety and response time to possible threats. 

But who has set these autonomous driving levels? It is defined by a global professional association called SAE International (Society of Automotive Engineers). Today, the U.S. Department of Transportation has adopted the ADAS levels and features to prevent the possibility of collision and enhance autonomous driving.

Want to know more about the levels of ADAS? No worries. Our blog will guide you. We will explore the basics of ADAS levels, their functions, and their importance. So, buckle up your seatbelt and set your eyes on the road for a rewarding journey. Let’s go!

How does ADAS technology help you drive?

ADAS is a technology that offers a suite of features designed to enhance safe driving and the driver’s capacity to react to potential road hazards. But how exactly does ADAS work in a vehicle? Well, an ADAS-powered vehicle incorporates a combination of cameras, ultrasonic sensors, and radar to provide the driver with a well-rounded understanding of their surroundings. 

Based on the information these sensors provide, the driver can make timely decisions and adjust their car’s movement. Hence, when the levels of ADAS technologies work together effectively, it not only reduces the risk of car accidents but also makes the road a safer place to drive. But what makes the ADAS technology a complete system for safe driving? It is its components. So, what are these components? Let’s see.

  • Sensors to detect objects

Sensors in ADAS include cameras, radars, LiDAR, GPS, ultrasonic, and infrared. These sensors work together and provide a comprehensive view of the vehicle’s surrounding environment. 

  • Electronic Control Unit (ECU) to process information

ECU is the heart of ADAS technology. This is because its key function is to process the information from the sensors and let the car take appropriate action, like applying brakes or steering the vehicle. 

  • Internet connectivity for remote monitoring

Connectivity in the ADAS system gives the driver over-the-air updates and reports. Besides, this component offers remote monitoring to figure out the repair issues on the vehicle. 

  • Data storage for future analysis

ADAS has a storage system that stores images from cameras and data from sensors to enhance the vehicle’s performance. Further, it is helpful for the vehicle’s future development. 

Top 6 levels of ADAS (Advanced Driver Assistance Systems)

Over the years, ADAS technology has transformed the automobile industry, making advanced car driving possible. Hence, it is no surprise that most companies are investing in this technology. Approving this fact, the statistics show that the global market value of ADAS will exceed USD 30 billion by 2030. So, see the ADAS levels explained in detail:

  • ADAS Level 0 – No driving automation

At level 0 of ADAS, the driver is solely responsible for driving the vehicle. That means the driver has to manage the car, from steering and braking to accelerating and slowing down. However, this level might have features like cameras to warn the driver of the collision but no control over the vehicle’s movement.

  • ADAS Level 1 – Driving assistance

This tier in the levels of ADAS features one automated system, like adaptive cruise control and lane departure warning. That means the ADAS can take control of the vehicle only in specific situations, giving alerts and signals. Therefore, the driver is still responsible for most aspects of the driving. 

  • ADAS Level 2 – Partial driving assistance

The Tesla ADAS level comes under this tier. Here, the vehicle will feature two or more automated systems, assisting the driver in steering and accelerating. However, the driver must stay alert and be ready to take control of the vehicle at any time if something goes wrong. 

  • ADAS Level 3 – Condition-based driving

Level 3 is one of the core levels of ADAS that enables drivers to detach from the process of driving, but only in specific situations. At this tier, the vehicle will take control of the driving process in conditions like highway driving. As a result, this level marks the first step toward autonomous driving. 

  • ADAS Level 4 – High driving automation

Here, the vehicle can drive itself in most situations by monitoring the driving environment, such as highways, roads, or other certain geographic areas. However, in environmental circumstances like thick snow, the vehicle warns the driver and demands the assistance of a human. 

  • ADAS Level 5- Full driving automation

Tier 5 in the levels of ADAS makes the vehicle capable of driving in all situations without any human intervention. At this level, no driving competence or license is needed to operate the car. Quite precisely, there is no need for the drivers to be present in the car. Though this level is unavailable for the consumer, it is just a matter of time.

In what ways are ADAS levels beneficial for safe driving?

With components like LiDAR sensors in ADAS technology, the market value of AD sensors will be USD 43 billion by 2030. What’s the reason behind this shoot-up? Well, these sensors provide three dimensions of areas and produce high-quality maps for the driver, which leads to smooth driving. However, the benefits of ADAS don’t end here. It’s more. Let’s see:

  • Enhance safe driving

The levels of ADAS use technologies designed to assist drivers by notifying them about potential dangers and preventing severe car accidents. Therefore, with the help of features like blind spot detection and driver drowsiness monitoring, ADAS can reduce the occurrence of accidents and enhance a better driving environment. 

  • Ensure comfort for drivers

The main purpose of ADAS technology is to offer the driver comfort and more convenience. Thus, features like automatic parking reduce the tension of drivers and assist them in parking in tight spaces with the help of sensors and cameras. 

  • Saves fuel consumption and cost

Since the six levels of ADAS can change the style of driving, it allows users to save the total consumption of fuel. Besides, ADAS supports automatic driving, which saves the environment from pollution and other disaster. 

What are the future predictions of ADAS technology?

At present, the automobile industry can produce level 3 autonomous vehicles. Hence, ADAS software development will require advanced technologies and procedures to provide users with a high-level driving experience. 

So, when will we see the top levels of ADAS? Well, it is all a question of time. Probably, in the coming years, we will see the adoption of levels 4 and 5, making driving a simple task. As a result, the future of ADAS will be bright and rewarding because it does the following:

  • Help reduce the scale to drive costs.
  • Make the automated driving experience more convenient.
  • Enhance traffic management and road safety for everyone.

So, leverage the best ADAS development service and make your driving seamless and enjoyable.


ADAS technology has entirely transformed the automobile industry with its benefits and features. Most companies and car enthusiasts want to invest their share in this technology to harness a safe driving future. In this blog, we have discussed the levels of ADAS technology. We hope you have gained insights on ADAS and its features. So, what are you looking for? Start your journey in ADAS now!
