Car safety features are continuing to improve, and one of the newer features to start leaking down into standard trims is blind-spot monitoring. Let’s take a look at how these systems work and why they’re so beneficial.
are made safer than ever nowadays with LED bulbs, adaptive movement, and anti-glare technology.
One of the most convenient features to be included on new cars today is blind-spot monitoring. Initially offered only on luxury vehicles, its availability has been expanded to even the cheapest models.
shows us how blind-spot monitors work and which cars have them.
How does blind-spot monitoring work?
Blind-spot monitoring is a system of sensors that's usually installed on the rear bumper or the side mirrors. When a vehicle is approaching the sensor, you may see a warning light on your side mirror or the A-pillar next to it.
Many basic blind-spot monitoring systems also emit an audible alert if there's another vehicle in your path when you're switching lanes. Some systems will even subtly manipulate your steering, discouraging you from merging at all. It's an incredibly useful feature to have at night, visibility-limiting weather conditions, or other dangerous driving scenarios.
Oftentimes, a blind-spot monitoring system will also include rear cross-traffic alert. RCTA uses the same types of sensors, but they're designed to work at lower speeds. For example, say you need to reverse out of your space in a crowded parking garage. RCTA lets you know when a vehicle is approaching from either end of the aisle.
However, even the most advanced blind-spot monitoring system has limitations. Most of them only work at speeds up to 35 mph, making them more useful in the city. These systems can also sometimes fail to detect narrow vehicles like bicycles and motorbikes.
You can still use BSM while you merge onto the highway, but not for much longer afterwards. Whenever possible, you should always look over your shoulder yourself to visually confirm that there's nothing in your blind spot.
Different automakers have built upon the basics of BSM and enhanced it with more innovative features. Some systems can now detect when a car will enter your blind spot even if it's three car-lengths back. Many trucks offer blind-spot monitoring systems for when you need to tow a trailer.
Of course, even a standard BSM system can be just as effective. MotorTrend suggests choosing ones with loud alert sounds and easily visible indicator lights. If you're looking for a better value, you can also check if it has RCTA or rear cross-traffic braking.
Different cars have different names for blind-spot monitors

BSM is referred to as the “Blind Spot Information System” on Honda and Acura models, equipped with a few extra smart features. BMW labels its system as “Active Blind Spot Detection”. Both Audi and Mercedes-Benz use the term “Side Assist” for their BSM systems.
No matter what it's called, a system that stays aware of your blind spots is a must-have for any driver. A few affordable cars, such as the Jeep Renegade, even have it installed on every trim.
Blind-spot monitors can directly contribute to lower car insurance premiums
If you're considered at fault for an auto accident, your insurance payments will definitely increase. Blind-spot monitors can help you avoid accidents because they can "see" an oncoming vehicle for you. This makes you less likely to experience those fender benders in the first place!
