Vehicle Safety Tech: Active and Passive Systems

Vehicle safety technology has come a long way, making our roads safer than ever before. Imagine a young family cruising down the highway on a sunny afternoon. Suddenly, a distracted driver swerves into their lane! Thanks to their car’s automatic emergency braking system, it reacts faster than any human could, bringing the car to a screeching halt inches away from disaster.

Did you know? Thanks to advancements like airbags, seatbelts, rearview cameras, and blind spot monitors, drivers today are nearly 60% more likely to survive a crash compared to drivers in the late 1950s. These safety technologies have collectively saved over 600,000 lives between 1960 and 2012.

Vehicle safety technology is like an invisible shield, working tirelessly to protect you and your passengers on the road. It’s your safety net. It’s that extra set of eyes and ears (or maybe even hands!) helping you navigate the unexpected.

What Are Active and Passive Safety Systems?

Vehicle safety tech is divided into two main categories: active safety systems and passive safety systems. Each type plays a crucial role in keeping you safe while driving.

Active Safety Systems: Preventing Accidents

Active safety systems are like your car’s first line of defense. They help prevent accidents before they happen.

An example of an active safety system that almost everyone is familiar with is anti-lock brakes (ABS). Introduced in the late 70s, ABS became standard equipment on nearly all cars by the late 90s. Anti-lock brakes prevent your car’s wheels from locking up during hard braking, allowing you to maintain steering control and reduce stopping distances on slippery surfaces. This helps you stay in control and avoid skidding.

In the years since the introduction of ABS, many other active safety technologies have been developed. Many newer cars have these, and more new cars will be equipped with them in the future.

active safety technologies in cars include lane departure warning
Lane Departure Warning
Alerts you if your vehicle begins to drift out of its lane without signaling
active safety technologies in cars include forward collision warning
Forward Collision Warning
Warns you of an impending collision with a vehicle or object directly in your path
active safety technologies in cars include adaptive cruise control
Adaptive Cruise Control
This system automatically adjusts your car’s speed to maintain a safe distance from the vehicle ahead
active safety technologies in cars include Electronic Stability Control
Electronic Stability Control (ESC)
This system helps you stay on track by automatically applying brakes to individual wheels if it senses your vehicle is losing control
active safety technologies in cars include blind spot monitors
Blind Spot Monitor
Alerts you to vehicles in your blind spots, making lane changes safer
active safety technologies in cars include automatic emergency braking
Automatic Emergency Braking
If a potential collision is detected, this feature can apply the brakes to help avoid or reduce the severity of an impact
active safety technologies in cars include drowsiness alerts
Drowsiness Alert
Monitors your driving patterns and warns you if it detects signs of drowsiness or inattention
active safety technologies in cars include rear cross traffic alerts
Rear Cross Traffic Alert
When backing out of a parking space, this system warns you of approaching vehicles from either side
active safety technologies in cars include bicycle detection
Bicycle Detection
This technology identifies cyclists on the road and can alert the driver or even apply the brakes to prevent a collision
active safety technologies in cars include pedestrian detection
Pedestrian Detection
Detects pedestrians in your vehicle’s path and can alert you or apply the brakes to avoid a collision

Passive Safety Systems: Protecting You in a Crash

Key passive safety features include:

  • Airbags—These cushion you during a crash, protecting your head and chest
  • Seat Belts—They keep you securely in your seat, preventing you from being thrown around
  • Crumple Zones—These are parts of your car designed to absorb the force of a crash, reducing the impact on you

Even with the best active safety systems, accidents can still happen. That’s where passive safety systems come in. These features protect you if a crash does occur.

Among all the safety systems in your car, seat belts are the only one you can control directly. Even though about 50% of people killed in car crashes weren’t wearing seat belts, only 92% of drivers consistently use them. Actively use your number one passive safety system—buckle up!

The Future of Vehicle Safety Tech

Vehicle safety technology is always evolving, with new advancements making our cars even safer. In the future, we can expect features like:

  • Autonomous Driving—Self-driving cars that can navigate traffic on their own, reducing human error
  • Vehicle-to-Vehicle Communication—Cars that can talk to each other to avoid accidents
  • Advanced Driver-Assistance Systems (ADAS)—Even smarter systems that help drivers stay safe on the road

Even if your car is equipped with all this tech, be careful. Studies have shown that as drivers become more familiar with these technologies, they are more likely to engage in distracted driving behaviors, such as texting or adjusting the radio. The most important safety feature of any vehicle is still the driver!

And That Brings Us Safely to the End

As we look to the future, it’s clear that vehicle safety technology will continue to evolve, making our roads even safer. By embracing these advancements and staying informed about the latest safety features, we can all contribute to a safer driving environment. Remember, the most effective safety feature is the one you use every time you get in the car—your seat belt. Stay vigilant, stay informed, and drive safely.
