Safety should be your No. 1 concern when you're behind the wheel. Most people address this matter with defensive driving and plenty of attention, but there's a slew of auto features that can help keep you secure in your ride. Among the most popular is rear cameras, which show drivers what's happening in the space directly behind a car, including areas lower to the ground that can often be blocked from view. 

Cameras increase safety
One recent study from AAA focused on the effectiveness of rear-view cameras. According to the report, these devices increased visibility by 36 percent in smaller sedans to nearly 75 percent in hatchbacks, with an average of 46 percent for all of the tested cars and trucks. Even the smallest improvement could prevent collisions, so the impressive range delivered by the cameras is a boon for many drivers. 

"Rear-view cameras are a great supplement for drivers," said John Nielsen, AAA's managing director of automotive engineering. "Cameras don't replace the need to check around your vehicle for obstacles before getting in to back up, but they do dramatically improve rear visibility. These systems are especially helpful for viewing the first 10 feet behind the vehicle, which are the most hazardous in terms of back-over risk for young children."

Many options for drivers
The good news is you don't have to pay a crazy amount of money for a brand new vehicle to take advantage of rear-view cameras. Not only are there a few lightly used models that boast this feature, but you can even buy the system separately and have it installed. The only difference is that you'll have to find space on your dashboard to fit the miniscreen. 

Cameras can be a big help, but they don't show the whole picture. Drivers still have to use their windows and mirrors, along with any other sensors, to ensure that they are safely maneuvering their cars. Additionally, the devices can be compromised by inclement weather, so be sure to clean them regularly. 

Rear-view cameras are going to be required on all new vehicles by the year 2016, but in the meantime, even drivers on a budget can tap into this technology. Looking for a car with these features?
