Federal safety officials say car makers should design potentially distracting dashboard technology so it's automatically disabled while the vehicle is in motion.
In recent years, automakers have been loading high-end cars with an array of built-in gadgets that enable drivers to multi-task behind the wheel.
That equipment enables text-messaging, internet browsing, GPS navigation, and phone dialing. But this technological advance has raised concerns that drivers' attentions will be diverted from the road.
The new dashboard technology guidelines include recommendations on how to make dashboard devices less distracting and time-consuming to use.
But the guidelines would exempt electronic-warning systems that alert drivers to potential collisions or lane changes.
