If you have driven for any length of time, you have undoubtedly been about to change lanes when — perhaps at the last second — you realize there is a car almost immediately next to you that is hiding in your “blind spot.” Collisions caused by blind spots are very common. Properly adjusting your side-mounted rearview mirrors can help, but an even better solution is the blind-spot monitor and warning.
Systems like these have cameras and/or sensors that can literally see where you can’t see. As part of their warning functions, they typically illuminate lights on or near your car’s exterior mirrors to signal that the lane immediately to your right or left is filled. Should you make a move in that direction — either by using your turn signal or with a steering wheel movement — the systems will emit audible warnings that you are about to make a costly misstep. Once the province of luxury cars, blind-spot warning systems can now be had in many less expensive vehicles. Here are the least expensive cars with a blind-spot warning.
