Prioritizing Car Safety
Safety is a paramount concern in used car sales, as it is what shields you from harm in the event of an accident. Prioritizing car safety features when selecting a used vehicle is not just about making a smart purchase—it’s a matter of life-saving importance. These features are not mere conveniences; they are the guardians of life on the road, drastically reducing the likelihood of fatal or serious accidents and enhancing overall road safety for drivers and passengers alike.
In the realm of used car sales, ensuring that the vehicle’s safety features are up to date and in full working order is a critical step in securing a safe driving experience. The used car market offers a plethora of options that can significantly diminish the risk of injury or death in a crash, including the invaluable safety features that are the focus of this guide.
Essential Safety Features Overview
Several safety features are absolutely non-negotiable. Electronic stability control (ESC) and the anti-lock braking system (ABS) are two such features that are essential for a safe driving experience. ESC helps to minimize the risk of skidding and losing control by automatically applying brakes to individual wheels, effectively ‘steering’ the car where the driver intends to go. Similarly, ABS prevents the wheels from locking up during braking, allowing the driver to maintain steering control and helping to reduce stopping distances, particularly on slippery surfaces.
Airbags, another crucial safety feature, provide cushioning and reduce the risk of injury in collisions by deploying upon impact to protect occupants.
Evaluating Safety Ratings
While features matter, gauging the overall safety rating of a used car is equally important. Organizations like ANCAP evaluate car safety and assign ratings from one to five stars, which incentivize manufacturers to prioritize safety improvements. Similarly, Used Car Safety Ratings provide critical insights for consumers looking to purchase a second-hand vehicle, assessing the relative safety level.
These ratings, compiled by the vehicle safety research group from data involving over 9 million vehicles in police-reported accidents in Australia and New Zealand, are indicative of the potential risk to drivers in terms of death or serious injury in a crash situation. A stark illustration of the value of these ratings: drivers in the lowest-rated vehicles are over eight times more likely to incur fatal or severe injuries compared to those in the highest-rated vehicles.
Advanced Driver Assistance Systems (ADAS)
With advancing technology, vehicle safety systems also evolve. Advanced Driver Assistance Systems (ADAS) are technologies that:
- Monitor the road environment
- Can autonomously intervene to prevent crashes or minimize the severity of an unavoidable collision
- Identify and react to potential hazards more rapidly than a human driver
- Help to prevent or mitigate crashes
These technologies are constantly improving and are an important step towards safer roads.
Studies have shown that vehicles equipped with ADAS technologies have a reduced rate of crashes and insurance claims compared to those without these systems.
Autonomous Emergency Braking (AEB)
Autonomous Emergency Braking (AEB), also known as automatic emergency braking, is one of the most significant ADAS technologies. It scans the road ahead and automatically applies the vehicle’s brakes when a potential obstacle is detected and the driver does not respond, aiming to avoid or reduce the impact of collisions.
This technology significantly enhances road safety by automatically activating the brakes to mitigate or avoid collision impacts.
Lane Departure Warning and Keeping Assist
Lane Departure Warning (LDW) and Lane Keeping Assist (LKA) are lane support systems that enhance driving safety by warning drivers of unintentional lane departures and assisting in steering control respectively. LDW systems alert drivers with visual, audible or haptic signals when the vehicle begins to cross lane markings without the use of turn signals, thereby informing the driver about potential unintended lane departures.
On the other hand, LKA systems actively engage the steering to correct the vehicle’s path and ensure it stays within the lane, offering a more proactive approach to lane discipline. These systems are often more effective than LDW in preventing lane departure crashes as they can take corrective steering action sooner than most drivers typically react to LDW alerts.
Adaptive Cruise Control and Forward Collision Warning
Other key ADAS technologies include Adaptive Cruise Control (ACC) and Forward Collision Warning. ACC automatically adjusts the vehicle’s speed to maintain a safe following distance from the vehicle ahead, slowing down and resuming speed based on traffic flow. It uses distance and speed sensors to monitor the gap to the car in front, managing vehicle acceleration and deceleration to keep up with traffic conditions. Some ACC systems even rely on radar waves to determine the distance, direction, and speed of objects ahead, ensuring the maintenance of a set gap from the vehicle in front.
The combination of adaptive cruise control with forward collision warning has been shown to reduce harsh braking events by 67%, highlighting its effectiveness in enhancing road safety.
Structural Integrity and Crash Protection
Beyond safety features and systems, the vehicle’s physical structure itself significantly contributes to safety. A vehicle with a strong and rigid structure can better absorb and distribute impact forces during collisions, enhancing the safety of occupants.
Crumple zones in vehicles enhance occupant safety during a collision by controlling the deformation, thereby extending the time over which the vehicle decelerates and reducing the force of impact experienced by occupants. The design of a vehicle’s structure plays a crucial role in its ability to protect passengers during a collision, as it can:
- Prevent the vehicle’s interior from intruding into the space occupied by passengers
- Distribute the forces of impact across the vehicle’s structure
- Absorb and dissipate energy from the collision
- Minimize the risk of injury to occupants
By incorporating effective crumple zones and a well-designed structure, vehicles can provide better protection for passengers in the event of a collision.
Additionally, side impact protection in vehicle designs is critical for reducing the risk of severe injuries during side collisions.
Crumple Zones and Vehicle Frame
Crumple zones, which are designed to deform during a crash, absorb and disperse energy. By deforming in a controlled manner, crumple zones reduce the forces transferred to the occupants, decreasing the risk of injury.
The vehicle frame, especially the central passenger compartment, is reinforced to remain rigid, protecting occupants along with crumple zones that absorb collision energy. The strategic weakening of certain vehicle parts like the front frame, paired with a sturdy passenger compartment, ensures that crash energy is absorbed effectively, thereby reducing the force of impact experienced by passengers.
Airbag Configuration
Airbags complement seat belts by absorbing passenger inertia and reducing the force on occupants during a collision. There are different types of airbags that serve different purposes:
- Front airbags, mandatory in all new vehicles, inflate during front crashes, protecting passengers from the vehicle interior.
- Side airbags deploy quickly to shield occupants’ heads and chests from side impacts with the vehicle structure or external objects.
- Curtain airbags act as a barrier to prevent occupants’ heads from hitting side windows or other vehicles during side impacts.
- Knee airbags help control the lower body and reduce leg injuries during collisions.
These different types of airbags work together to provide enhanced safety for vehicle occupants.
Seat Belt Systems
Seat belts, arguably the most fundamental yet critical safety feature in cars, are integral to protecting occupants during a crash. They are designed to:
- Retain people in their seats, and so prevent or reduce injuries suffered in a crash
- Ensure that as little contact is made between the occupant and vehicle interior as possible
- Significantly reduce the risk of being thrown from a vehicle.
Pre-tensioners and Load Limiters
Pre-tensioners in seat belts have the following benefits:
- They tighten the belt instantly in the event of a collision, securing the occupants swiftly
- They reduce the forward movement of the occupants, minimizing the risk of injury
- By eliminating slack in seat belts when a crash occurs, pre-tensioners ensure that occupants are restrained effectively
These features make pre-tensioners an important safety component in vehicles.
Load limiters work alongside pre-tensioners to manage the amount of force exerted on an occupant’s body by gradually releasing seat belt tension once a specific threshold is reached.
Following a collision in which they’ve been activated, pre-tensioner seat belt systems require replacement as they are single-use components.
Rear Seat Belts
Rear seat belts are also crucial for the proper restraint of passengers, especially children, reducing the risk of injury in a crash. In addition to the driver and front passenger, all occupants should be properly secured.
Inspecting rear seat belts is crucial to ensure the safety of all passengers, particularly children who are more likely to occupy the rear seats.
Visibility and Lighting
Visibility is also a pivotal factor for safe driving. Adequate visibility allows the driver to make timely decisions, such as when to slow down, speed up, or avoid obstacles. Proper automotive lighting enhances visibility, which is crucial for safe driving, and it allows drivers to see the road ahead clearly while making the vehicle noticeable to others.
Headlights and Taillights
Headlights and taillights are essential for visibility, especially during night driving or adverse weather conditions, and they must function properly to ensure safety. Well-functioning headlights and taillights are crucial for a vehicle’s visibility to other road users, especially during night driving or in poor weather conditions.
Bright and fully functional tail lights are essential to ensure a vehicle is visible from the rear, which helps in decreasing the chance of rear-end collisions. Regular maintenance, like cleaning headlights and replacing faulty bulbs, is vital to maintain optimal visibility and safety on the road.
Blind Spot Monitoring
Blind spot monitoring systems are crucial for enhancing driver awareness, particularly for detecting vehicles that are not visible in the side mirrors. These systems alert drivers through visual, audio, or haptic signals when a vehicle is present in the blind spot area, aiding in safe driving maneuvers.
The presence of blind spot monitoring in a used car adds a layer of safety by assisting drivers during lane changes, a common scenario for vehicle collisions. Having this system can significantly reduce the potential for side-impact collisions by detecting and alerting the driver to vehicles that may otherwise be missed.
