What Is Adaptive Cruise Control, and Is It Safe?

Modern vehicles come equipped with increasingly advanced technologies to improve safety. One of the most notable of these features is Adaptive Cruise Control (ACC), which adjusts a vehicle’s speed based on surrounding traffic–but how exactly does it work, and is it safe? 

Here is what you need to know about adaptive cruise control and its advantages and limitations.

What Is Adaptive Cruise Control?

Adaptive cruise control is a type of advanced driver assistance system (ADAS) that automatically adjusts a vehicle’s speed to maintain a safe following distance from the car ahead unlike traditional cruise control, which keeps your car at a set speed until manually disengaged.

Some newer ACC systems even include stop-and-go capability, allowing a vehicle to come to a complete stop and resume movement in heavy traffic.

Advantages of Adaptive Cruise Control

Adaptive cruise control is designed to increase safety. It is a valuable addition to many vehicles that can:

  • Reduces driver fatigue: ACC can reduce driver fatigue during long trips by handling routine speed adjustments.
  • Maintains safe following distance: ACC automatically maintains a buffer between vehicles to minimize tailgating and rear-end collisions.
  • Improves traffic flow: Vehicles equipped with adaptive systems may help reduce stop-and-go traffic.
  • Enhances safety: ACC works alongside lane-keeping assist, automatic emergency braking, and other safety features to enhance safety.

These benefits can improve the driving experience and potentially reduce the likelihood of certain types of accidents, especially on highways.

Limitations and Safety Concerns of Adaptive Cruise Control

Adaptive cruise control is not without its limitations. Drivers should be aware of the following issues when using ACC:

  • Not a substitute for driver attention: ACC does not make a vehicle self-driving. Drivers must stay alert and be ready to take control at all times.
  • Weather interference: Rain, snow, fog, or dirt can obstruct ACC radars or camera sensors, affecting accuracy.
  • Limited response to sudden stops: ACC may not react quickly enough if another car suddenly cuts in front of you or slams on the brakes.
  • False sense of security: Some drivers may rely too heavily on ACC, increasing the risk of speeding or distracted driving.

These limitations highlight the need for constant driver supervision, even when ACC is engaged.

As more vehicles adopt semi-automated features like ACC, questions about liability in crashes involving these technologies are becoming increasingly important. If a driver causes a crash while using adaptive cruise control, they can still be held liable, especially if they were distracted or failed to take control when needed.

Product liability claims may also arise if an ACC system malfunctions or fails to detect a vehicle, causing a collision. A San Diego product liability lawyer can help hold manufacturers, software developers, or component suppliers who could potentially be held responsible in these situations. 

Should You Use Adaptive Cruise Control?

Adaptive cruise control can be a valuable aid when used properly, particularly on highways or during long commutes. However, it should never replace the driver’s judgment or attention. If you choose to use ACC, follow these tips:

  • Always keep your hands on the wheel and your eyes on the road.
  • Use ACC only in suitable conditions, such as dry weather and light-to-moderate traffic.
  • Regularly inspect and clean your vehicle’s sensors and cameras.
  • Learn how your specific system operates by reviewing your vehicle’s owner manual.

Following these tips can help keep you and other drivers safe on California roads.

Try Adaptive Cruise Control, but Be Cautious

Adaptive cruise control is a powerful tool that offers increased comfort and an added layer of safety when used responsibly. However, it is not foolproof. Drivers must stay engaged, understand the system’s limitations, and be prepared to act when needed. 

If you were involved in a crash involving adaptive cruise control, reach out to an experienced personal injury lawyer. A skilled personal injury lawyer can help determine liability, evaluate your case, and fight for the compensation you deserve.
