Automatic Brakes Will Be in All Cars by 2022: What to Know About the New Standards

Car makers say automatic emergency braking will be standard in 6 years.

— -- intro: Automatic emergency braking will no longer be a high-tech option in pricey cars. In six years, the feature will be standard in all new cars, auto makers and regulators announced today.

Twenty auto makers representing more than 99 percent of the U.S. car market announced with the U.S. Department of Transportation their commitment to making it a standard feature by Sept. 1, 2022.

This follows the requirement announced by the DOT in 2014 that backup cameras will be required in all vehicles built in and after May 2018.

Here's what you need to know about the commitment and the car feature:

quicklist: title: What is automatic emergency braking? text: Automatic emergency braking can help prevent car crashes or reduce their severity by applying brakes for the driver. The system uses sensors such as radar, cameras or lasers to detect an imminent crash, warning the driver and applying the brakes if the driver doesn't respond quickly enough.

The agreement announced today affects nearly all light-duty cars and trucks with a weight of 8,500 pounds or less by Sept. 1, 2022. The deadline extends three years later for trucks weighing between 8,501 pounds and 10,000 pounds.

The systems must meet the NHTSA's five-star safety ratings program on the timing of driver alerts. The baseline performance measures are a speed reduction of at least 10 mph in either 12 or 25 mph tests, or a speed reduction of 5 mph in both of the tests.

Every time a new safety technology becomes standard on modern cars it adds to the costs of production, Karl Brauer, senior analyst for Kelley Blue Book, told ABC News.

"Each of these technologies is relatively small in expense, usually only a few hundred dollars, but in aggregate they can result in a substantial portion of a car's price, especially for lower-priced models," Brauer said. "The rising cost of modern cars is driven by many factors, and this is definitely one of them.”
