Driving assistance systems: What you need to know

What role do driver assistance systems play in today’s vehicles?

Nearly nine out of ten vehicles sold at a dealership come equipped with at least one active or passive driver assistance feature. With names like ProPilot, Distronic Plus, Super Cruise, PreSense Assist, and Active Safe, consumers can easily feel overwhelmed. This has even prompted the American Automobile Association (AAA) to call for standardized terminology.

One thing is certain: when used properly, these systems can help prevent collisions and save lives.

What are the most common advanced driver assistance systems?

These systems support you in your day-to-day driving while also protecting other road users:

• Lane-departure warning (LDW)
• Blind-spot monitoring (BSM)
• Automatic emergency braking (AEB)
• Adaptive cruise control
• Lane-keeping assist (LKA)
• Traffic sign recognition
• Pedestrian and cyclist detection systems
• Parking assist

Do driver assistance systems actually make roads safer?

Yes, when used correctly. These features contribute to safer driving by reducing property damage by up to 27%¹ and bodily injury by up to 37%¹. The automatic emergency braking system, for example, can detect objects in real time, alert the driver, and apply the brakes on its own if necessary. 

What are the limitations of driver assistance systems?

Despite their effectiveness, these systems are not foolproof:

• Sensors can be obstructed by snow, ice, or mud.
• Performance is reduced at night or in low-visibility conditions.
• They never replace human attentiveness.

Why is it important to understand how these systems work?

Every driver assistance system has its own characteristics. Your owner’s manual remains your best reference for understanding how they actually work. For example:

• Does your adaptive cruise control function at all speeds, including in heavy traffic?
• Does your lane-change assist simply signal with a sound, or does it also correct your trajectory?

The more familiar you are with the systems in your vehicle, the better positioned you’ll be to use them effectively.

Good to know: To remain reliable, several assistance features must be recalibrated by a specialist after a collision, a windshield replacement, or a repair.

Can driver assistance systems increase the risk of distracted driving?

They can, as they sometimes create a false sense of security behind the wheel. Yet distracted driving remains one of the leading causes of accidents. Like other technologies around us, these systems are not perfect. It’s therefore important to keep your eyes on the road at all times.

How can you avoid distraction using the CAP method?

Searching for an address on your phone, changing the music, or using the onboard computer can all distract you. Fortunately, the CAA-Quebec Foundation offers a method to help you reduce the risks. It’s called UPP (Understand, Pair, Program):

• Understand how your multimedia system works.
• Pair your mobile device before hitting the road.
• Program your settings before you start driving.

Do driver assistance systems affect the cost of car insurance?

Not at this time. Driving a vehicle equipped with advanced driver assistance systems does not directly affect the cost of your insurance, since not all vehicles are equipped with these systems.

Driver assistance systems are a valuable support tool, but they will never replace your attentiveness—which remains essential for road safety. To make the most of them, take the time to understand how they work. Respect their limitations and keep your eyes on the road.
