A rearview mirror may seem like a simple part of a car, but it plays an important role in safe driving. It helps a driver see traffic and other road users behind the vehicle without having to turn around. Drivers use it when changing lanes, slowing down, parking, and watching traffic.
Rearview mirrors work with side mirrors to give drivers a wider view around their vehicles. However, mirrors cannot show every area around a car. Drivers still need to pay attention to blind spots and check around them before making a move.
How Does a Rearview Mirror Help a Driver?
The main purpose of the inside rearview mirror is to show what is happening behind the car. A driver can quickly look at the mirror while keeping most of their attention on the road ahead.
The mirror can help a driver notice a vehicle that is following too closely or approaching quickly. It can also help when the driver plans to slow down, stop, or change lanes.
Federal vehicle safety rules include requirements for rear visibility “to reduce the number of deaths and injuries that occur when the driver of a motor vehicle does not have a clear and reasonably unobstructed view to the rear.”
When Should Drivers Check Their Rearview Mirrors?
Drivers should check their mirrors often instead of waiting until they need to turn or change lanes. Regular checks can help drivers understand what is happening around their cars.
A rearview mirror can be useful when:
- Changing lanes or merging with traffic
- Slowing down or stopping
- Preparing to make a turn
- Watching a vehicle that is following closely
- Backing up or parking
- Checking for motorcycles, bicycles, and other road users
Mirror checks should be quick so drivers can return their attention to the road ahead.
Rearview Mirrors and Blind Spots
A rearview mirror does not provide a complete view around a car. There may still be areas where another vehicle, motorcycle, bicycle, or person cannot be seen. These areas are called blind spots.
The National Highway Traffic Safety Administration (NHTSA) explains that inside and outside mirrors can help drivers see vehicles and people around them, but mirrors do not show everything. NHTSA recommends adjusting outside mirrors to improve visibility and checking over your shoulder before changing lanes.
Drivers should make sure their mirrors are adjusted before starting a trip.
Are Rearview Mirrors Required in Georgia?
Georgia law has rules about mirrors on motor vehicles. In Georgia, a motor vehicle that is built or loaded in a way that blocks the driver’s rear view must have a mirror positioned to show the highway for at least 200 feet behind the vehicle.
Federal safety standards also set requirements for mirrors on new passenger vehicles. These rules address matters such as the mirror’s field of view and placement.
Having the required mirrors is important, but drivers must also use them properly. A mirror that is dirty, damaged, blocked, or poorly adjusted may make it harder to see surrounding traffic.
Can a Rearview Mirror Help Prevent Car Accidents?
A properly adjusted rearview mirror can help a driver make safer choices. For example, checking behind the vehicle before slowing down may alert the driver to a car that is following too closely. Checking mirrors before changing lanes can also help reveal nearby traffic.
Still, mirrors cannot prevent every crash. Drivers should combine mirror checks with turn signals, safe following distances, and shoulder checks when needed.
Newer cars may also have backup cameras and blind spot warning systems. NHTSA describes these technologies as tools that can provide drivers with more information about areas around their vehicles. They do not replace careful driving or the need to watch the road.
