A side-view mirror (or side mirror), also known as a door mirror and often (in the UK) called a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside the driver's peripheral vision (in the "blind spot").
Almost all modern cars mount their side mirrors on the doors—normally at the A-pillar—rather than the wings (the portion of the body above the wheel well).
The side mirror is equipped for manual or remote vertical and horizontal adjustment so as to provide adequate coverage to drivers of differing height and seated position. Remote adjustment may be mechanical by means of bowden cables, or may be electric by means of geared motors. The mirror glass may also be electrically heated and may include electrochromic dimming to reduce glare to the driver from the headlamps of following vehicles. Increasingly, the side mirror incorporates the vehicle's turn signal repeaters. There is evidence to suggest that mirror-mounted repeaters may be more effective than repeaters mounted in the previously predominant fender side location. [1]
Through the 1940s, most roads had just two lanes, one in each direction. Drivers usually had to be aware only of traffic ahead of and directly behind them. Due to this, early cars had just a single rear-view mirror mounted on the top of the windshield or on top of the dashboard. When side mirrors were introduced to help drivers see overtaking vehicles, most cars only had the driver side mirror as standard equipment. A passenger side mirror was optional on most cars through the 1970s. Today all 3 mirrors are standard on almost all passenger vehicles.
In the U.S. and Canada, the U.S. National Highway Traffic Safety Administration's Federal Motor Vehicle Safety Standard 111 and the Canada Motor Vehicle Safety Standard 111 require the driver-side mirror to provide "unit magnification", i.e., an undistorted 1:1 reflection achieved with a flat mirror. However, unit magnification limits the field of view that can be provided by a mirror of size compatible with the vehicle body. The ECE regulations in use throughout most of the world except North America permit the driver-side mirror to have a planar, convex, or aspheric surface; an aspheric section is often combined with a larger convex section, and the two sections are separated by a visible line to alert the driver to the two sections' different perspective shifts. [2] [3]
Because of the distance from the driver's eye to the passenger side mirror, a useful field of view can be achieved only with a convex or aspheric mirror. However, the convexity also minifies the objects shown. Since such objects seem farther away than they actually are, a driver might make a maneuver such as a lane change assuming an adjacent vehicle is a safe distance behind, when in fact it is quite a bit closer. [4] In the United States, [5] Canada, [6] India, Korea and Australia [ citation needed ], non-planar mirrors are etched or printed with the warning legend objects in the mirror are closer than they appear . In Canada, this warning is often supplemented by a transparent decal on the passenger side window repeating the warning in French: les objets dans le retroviseur sont plus proche qu'ils ne le paraissent. In Korea, the warning appears in Korean. Warnings of this nature are not required in Europe.
More commonly in cars manufactured since the 2000s, side mirrors may be manually or electrically folded in, to protect them when the car is parked or being washed in an automated car wash.[ citation needed ] Passing cars can easily clip protruding side mirrors; the folding capability helps protect them from harm. ECE Regulation 46 requires that side mirrors be mounted such that they swing away when struck by a test cylinder meant to represent a pedestrian. [7]
Until March 1983, the Japanese Ministry of Transport did not allow cars to be registered without mirrors on front fenders, [8] so the mirrors were mounted far forward atop the front fenders. More recent Japanese-specification vehicles have side mirrors similar to those in other countries. [9] Taxi drivers and other professional drivers retain a preference for the wing-mounted mirrors as they feel that they work better in extremely tight traffic. [9]
U.S. Federal Motor Vehicle Safety Standard 111 requires that convex side-view mirrors must have a curvature radius of between 889 mm and 1651 mm. [5] Canada Motor Vehicle Safety Standard 111 stipulates a range of between 890 mm and 1800 mm. [6] Neither the U.S. nor the Canadian standard allows for aspheric mirrors. [3] The European ECE Regulation 46 used throughout most of the world permits planar, convex, and/or aspheric mirrors on either side of the vehicle. [3] [7] American research suggests non-planar driver side mirrors may help reduce crashes. [2] [10]
In 2018, side mirrors in a form of camera and display were introduced for a better peripheral recognition upon driving. It has advantages over conventional ones as it may provide wider angle of sight and less air resistance without obstructing driver's frontal view, though the first of these problems can be alleviated in regular mirrors by adjusting them such that the view presented offers only minimal overlap with that of the interior mirror. [11]
Problems with digital mirrors include difficulties relating to the inherent lack of binocular vision (such as impaired depth perception, and the requirement for the viewer to readjust focus to the distance of the mirror surface instead of merely the distance to the object), as well as from problems related to both the reduced dynamic range and the sensitivity of a camera in low light conditions. This type of mirror also needs power to function.
These side mirrors are installed on various types of vehicles such as Hyundai Ioniq 5, Audi e-tron. Mercedes-Benz introduced such a system 2018 in the Actros under the name "MirrorCam".
A blind spot in a vehicle or vehicle blind spot is an area around the vehicle that cannot be directly seen by the driver while at the controls, under existing circumstances. In transport, driver visibility is the maximum distance at which the driver of a vehicle can see and identify prominent objects around the vehicle. Visibility is primarily determined by weather conditions and by a vehicle's design. The parts of a vehicle that influence visibility include the windshield, the dashboard and the pillars. Good driver visibility is essential to safe road traffic.
A school bus is any type of bus owned, leased, contracted to, or operated by a school or school district. It is regularly used to transport students to and from school or school-related activities, but not including a charter bus or transit bus. Various configurations of school buses are used worldwide; the most iconic examples are the yellow school buses of the United States which are also found in other parts of the world.
The Nissan Fuga is a mid-size luxury sedan produced by Japanese automaker Nissan since October 2004. It is built on a wider, stretched wheelbase version of the Nissan FM platform. After the Nissan Cima and Nissan President were discontinued in August 2010, the Fuga became Nissan's flagship vehicle. In North America and Europe, the Fuga was sold as the second and third-generation Infiniti M and Infiniti Q70, where it was the flagship sedan of the Infiniti luxury division of Nissan from 2006 to 2019.
In road-transport terminology, a lane departure warning system (LDWS) is a mechanism designed to warn the driver when the vehicle begins to move out of its lane on freeways and arterial roads. These systems are designed to minimize accidents by addressing the main causes of collisions: driver error, distractions and drowsiness. In 2009 the U.S. National Highway Traffic Safety Administration (NHTSA) began studying whether to mandate lane departure warning systems and frontal collision warning systems on automobiles.
The Nissan Titan is a full-size pickup truck manufactured in the United States for the North American market by Nissan. It was named after the Titans of Greek mythology.

The Cadillac Series 70 is a full-size V8-powered series of cars that were produced by Cadillac from the 1930s to the 1980s. It replaced the 1935 355E as the company's mainstream car just as the much less expensive Series 60 was introduced. The Series 72 and 67 were similar to the Series 75 but the 72 and 67 were produced on a slightly shorter and longer wheelbase respectively. The Series 72 was only produced in 1940 and the Series 67 was only produced in 1941 and 1942. For much of the postwar era, it was the top-of-the-line Cadillac, and was Cadillac's factory-built limousine offering.
A motor vehicle has lighting and signaling devices mounted to or integrated into its front, rear, sides, and, in some cases, top. Various devices have the dual function of illuminating the road ahead for the driver, and making the vehicle visible to others, with indications to them of turning, slowing or stopping, etc., with lights also indicating the size of some large vehicles.
The World Forum for Harmonization of Vehicle Regulations is a working party (WP.29) of the Inland Transport Committee (ITC) of the United Nations Economic Commission for Europe (UNECE). Its responsibility is to manage the multilateral Agreements signed in 1958, 1997 and 1998 concerning the technical prescriptions for the construction, approval of wheeled vehicles as well as their Periodic Technical Inspection and, to operate within the framework of these three Agreements to develop and amend UN Regulations, UN Global Technical Regulations and UN Rules, kind of vehicle regulation.
The Mercedes-Benz Actros is a heavy-duty truck introduced by Mercedes-Benz at the 1996 Commercial Vehicle IAA in Hannover, Germany, as the replacement for the SK. It is normally used for long-distance haulage, heavy-duty distribution haulage, and construction haulage. It is powered by an inline-6 diesel engine with a turbocharger and intercooler. In 2002, Daimler Trucks/Lorries launched version II of the Actros and in 2007, launched the version III. The fourth generation of the Actros, officially named "the New Actros", was launched in July 2011.
The blind spot monitor or blind-spot monitoring is a vehicle-based sensor device that detects other vehicles located to the driver’s side and rear. Warnings can be visual, audible, vibrating, or tactile.
Parking sensors are proximity sensors for road vehicles designed to alert the driver of obstacles while parking. These systems use either electromagnetic or ultrasonic sensors.
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. Distorting mirrors are used for entertainment. They have convex and concave regions that produce deliberately distorted images. They also provide highly magnified or highly diminished (smaller) images when the object is placed at certain distances.
A backup camera is a video camera specifically designed to be attached to the rear of a vehicle to aid in reversing and reduce the rear blind spot. The rear blind spot has been described as a "killing zone" due to the accidents it contributes to. Backup cameras are usually connected to the vehicle's head unit display. A common variant is a surround-view system, which assembles a synthetic but positionally accurate top-down view of the vehicle and its surroundings.
Vehicle regulations are requirements that automobiles must satisfy in order to be approved for sale or use in a particular country or region. They are usually mandated by legislation, and administered by a government body. The regulations concern aspects such as lighting, controls, crashworthiness, environment protection and theft protection, and might include safety belts or automated features.
Government regulation in the automotive industry directly affects the way cars look, how their components are designed, the safety features that are included, and the overall performance of any given vehicle. As a result, these regulations also have a significant effect on the automotive business by generally increasing production costs while also placing limitations on how cars are sold and marketed. Automotive regulations are designed to benefit the consumer and protect the environment, and automakers can face stiff fines and other penalties if they are not followed.
A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system (FCW), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar (all-weather) and sometimes laser (LIDAR) and cameras to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems.
The phrase "objects in (the) mirror are closer than they appear" is a safety warning that is required to be engraved on passenger side mirrors of motor vehicles in many places such as the United States, Canada, Nepal, India, and South Korea. It is present because while these mirrors' convexity gives them a useful field of view, it also makes objects appear smaller. Since smaller-appearing objects seem further away than they actually are, a driver might make a maneuver such as a lane change assuming an adjacent vehicle is a safe distance behind, when in fact it is quite a bit closer. The warning serves as a reminder to the driver of this potential problem.
Back-up collisions happen when a driver reverses the car into an object, person, or other car. Although most cars come equipped with rear view mirrors which are adequate for detecting vehicles behind a car, they are inadequate on many vehicles for detecting small children or objects close to the ground, which fall in the car's blind spot, particularly directly aft. That area has been called a "killing zone." Large trucks have much larger blind spots that can hide entire vehicles and large adults.
The Cadillac DeVille is a model name used by Cadillac over eight generations, originally used to designate a trim level of the 1949 Cadillac Series 62 and later to designate a standalone model in the brand range. The last model marketed specifically as a DeVille was the 2005 full-size sedan, at the time, Cadillac's largest model.
Surround view, also called as around view or birds-eye view, is a type of parking assistance system that uses multiple cameras to help drivers monitor their surroundings. It was first introduced in 2007 as the "Around View Monitor" parking assistance option for the Nissan Elgrand and Infiniti EX.
