Many vehicles today have features that give parents extra control over their teens’ driving, but salespeople often require prompting before they mention them to prospective buyers, researchers from the Insurance Institute for Highway Safety has found.

Teen safety features, including parents being able to limit the speed of their child’s vehicle, keep track of its whereabouts or prevent it from being put in gear if the driver hasn’t buckled are all available, but the research reveals that often parents are unaware of them.

“Vehicle monitoring systems can improve the behavior of teen drivers and reassure their parents,” said IIHS Research Scientist Rebecca Weast, the study’s lead author.

“Dealers could make this a bigger selling point with parents shopping for their new drivers.”

IIHS researchers also found that, for most of the brands studied, consumers would have to spend a significant amount of time sifting through information before finding teen safety features.

The IIHS says manufacturer websites could also do more to promote the features.
