What Does The Term Blind Spot Mean For A Driver?
Blind spots are the areas to the sides of your car that can’t be seen in your rear mirror or side mirrors- to make sure these spots are clear before changing lanes, you'll have to physically turn around and look to see what kind of crazy stuff is going on out there. Driving blind spot where the blue shaded area is blind If the red car driver wants to change over to the left lane where the yellow car is, he will first need to look into his interior mirror, followed by the left door mirror and then briefly look over his left shoulder to check the left blind spot before changing lanes.

If a vehicle is detected there, drivers get a visual warning, often in the outboard mirrors, or on the front pillars. The system may provide an additional warning if the turn signal is activated when it is unsafe to merge or change lanes.
In a most recent survey, we asked CR members to rate their experiences with the advanced safety and driver-assist systems on their model-year cars. Respondents wht questions about their satisfaction with the systems drivkng told us which ones helped them avoid a crash. The survey covered about 72, vehicles. See the highlights below. It has saved me and my wife from numerous accidents, and we would never buy another car without it! What were they thinking? In bumper to bumper traffic it doesn't work!
Or [in] slow moving traffic. Plus the light isn't in the mirror so it's not immediately apparent if the light is on. Also hard to see if it's too sunny. CR gives bonus points to models that have it as standard equipment across all trims, and our members also rate it favorably. It makes for safer lane changes, a real boon for drivers in vehicles with big blind spots.

How this technology improves safety by monitoring a vehicle's flanks
A blind spot is an area around the vehicle that the driver cannot observe with the instrumentation available to them without turning their heads. For instance, there might be another vehicle on the inside lane of the motorway right next to you while you’re driving. Aug 05, · Blind spot warning (BSW) systems use cameras, radar, and/or ultrasonic sensors alongside your vehicle to detect vehicles you can’t see that are next to or behind your car. If a vehicle is detected. In driving terms, the blind spot is the area that cannot be seen in either the interior or door mirrors. The interior mirror gives a true picture of what is directly behind you, whereas the door mirrors make objects appear further away.
A blind spot in a vehicle is an area around the vehicle that cannot be directly observed by the driver while at the controls, under existing circumstances. Other types of transport have no blind spots at all, such as bicycles , horses , and motorcycles.
Proper adjustment of mirrors and use of other technical solutions can eliminate or alleviate vehicle blind spots. A no zone is one of several areas around a large truck, where the truck driver cannot see. In transport , driver visibility is the maximum distance at which the driver of a vehicle can see and identify prominent objects around the vehicle. Good driver visibility is essential to safe road traffic. Blind spots may occur in the front of the driver when the A-pillar also called the windshield pillar , side-view mirror , or interior rear-view mirror block a driver's view of the road.
Behind the driver, cargo, headrests, and additional pillars may reduce visibility. If the side view mirrors of a car are adjusted in a particular way, there is no blind spot on the sides. This method was first revealed by George Platzer in a paper presented to the Society of Automotive Engineers. It is reputed to be a lifesaver. However, one source considers that method a driving mistake and claims it is even more dangerous than not using it, because it creates other blind spots directly behind the vehicle—nine reasons are listed, e.
Rearward invisibility is an entirely different matter. The area directly behind vehicles is the source of back-up collisions , particularly involving pedestrians, children, and objects directly aft of a vehicle.
That area has been called a "killing zone". A similar problem attaches to positions left and right of a vehicles' rear bumper as the driver attempts to back out of a parking space. Specially designed cross traffic alert warning systems have been developed to address these.
As one is driving an automobile , blind spots are the areas of the road that cannot be seen while looking forward or through either the rear-view or side mirrors expecting that the side mirrors are properly adjusted on a passenger auto — see above.
The most common are the rear quarter blind spots, areas towards the rear of the vehicle on both sides. Vehicles in the adjacent lanes of the road that fall into these blind spots may not be visible using only the car's mirrors.
Rear quarter blind spots can be:. Other areas that are sometimes called blind spots are those that are too low to see behind, in front, or to the sides of a vehicle, especially those with a high seating point. This diagram shows the blocked view in a horizontal-plane in front of the driver. The front-end blind spots caused by this can create problems in traffic situations, such as in roundabouts , intersections , and road crossings.
Front-end blind spots are influenced by the following design criteria:. Most passenger cars have a diagonal pillar in the side view. The angle between the horizon and A-pillar is approximately 40 degrees with a straight pillar that is not too thick. This gives the car a strong, aerodynamic body with an adequately sized front door.
The sides of a panoramic windshield are curved, which makes it possible to design vertical A-pillars that give the driver maximum forward visibility. However, it is impossible to design an aerodynamic small car with a vertical A-pillar because the more vertical the A-pillar is, the less space the door opening has, and the greater frontal area and coefficient of drag the vehicle will have.
Some modern car designs have an extremely flat A-pillar angle with the horizon. A flatter A-pillar and therefore windscreen is also a factor when calculating the effects of a collision with a pedestrian. In general a flatter angle will result in a more gentle impact, directing the pedestrian "up and over" rather than directly into the windscreen. This is particularly true for cars like the Mercedes-Benz A-Class which also have a low angled engine cover. An A-pillar that is split up and has a small triangle window Front Quarter glass can give a short driver visibility problems.
Some cars the windshield is fillet with the roof-line with a big radius. A fillet round A-pillar can give a tall driver visibility problems. Also sometimes the A-pillar can block the driver from seeing motorcyclists. Also the B-pillar can block the vision of a tall driver in small 4 door cars. A driver may reduce the size of a blind spot or eliminate it completely by turning their head in the direction of the obstruction.
This allows the driver to see better around the obstruction and allows the driver better depth perception. Because there is no roof connection between the A- and B-pillars, the A-pillars of a convertible automobile have to be stronger and even thicker. It is best if the dashboard has a non-reflecting dark colored surface. It is best if the inside of the A-pillar has a non-reflecting dark colored surface. If the side of the window is curved there is less A-pillar reflection.
Some new model cars have a very big sunroof. Sometimes the sunlight through the roof lights up the dashboard and gives a reflection in the windshield. Other design factors may prevent a manufacturer from maximizing visibility. These include safety, as narrower pillars cannot be made strong as easily as thicker pillars, and size restraints pertaining to aerodynamics, as taller, more vertical windshields create additional drag and reduce fuel efficiency. They also include fashion and cost, whereby design and appearance considerations can be deemed preeminent.
This system was first introduced in the Volvo S80 sedan and produced a visible alert when a car entered the blind spot while a driver was switching lanes, using two door mounted lenses to check the blind spot area for an impending collision. Some newer and more costly systems use side radar offering better performance and also warn of fast approaching vehicles entering the blind spot.
Blind spots also exist in front of boats. Large vessels can have up to several hundreds of meters of blind spot. This is generally known as the dead visual range of a ship. To address this, cameras are sometimes placed in the front of the vessel to cover the missing field of view.
Blind spots exist where areas behind the sail are obscured from the view of a helmsman on a sailboat or windsurfer. This is especially true when they are heeled over ; consequently, transparent windows are sometimes sewn into the sails. From Wikipedia, the free encyclopedia.
