Starting next year，Ford Motor Co．will allow parents to limit the speed at which their teenage children drive their car．
The company will make a new feature on many models that can limit teen drivers to 80mph（130kph），using a computer chip（芯片） in the key．
Parents in the United States，where most teens can get their driving license at 16，also have the option of programming the car key to limit the audio system volume（音量），and to sound continuous alarm if the driver doesn't wear a seat belt．
More than half of parents surveyed worry that their teenage children are driving at unsafe speeds，talking on hand-held cell phones or texting while driving，or otherwise driving without due care and attention．More than a third of parents also are concerned that their teens do not always fasten their safety belts when driving．
"Our message to parents is，hey，we are proving you some conditions to give your new drivers that may allow you to feel a little more comfortable in giving them the car more often，"said Jim Buczkowski，Ford's director of electronic and electrical systems engineering．
More than 5，000US teens die each year in car crashes．The rate of crashes，fatal（致命的） and nonfatal，per mile driven for 16-year-old drivers is almost 10times the rate for drivers aged 30to 59，according to the National Highway Traffic Safety Administration．
The new feature，called"MyKey"，will be standard on an unspecified number of Ford models when the new models come out late next summer．The feature will spread to the entire Ford，Lincoln and Mercury Lineup as models are updated，spokesman Wes Sherwood said．
The company already uses computer chips in its keys to prevent thefts．The car won't start unless it recognizes the chip in the key．
"It's making use of existing technology，and through the magic of software，we're able to build features on top of the features we already have，"Buczkowski said．
