You are 30 years old and drive through a school zone while its yellow lights flash and the lower school speed limit applies. Your phone rings, and it is not an emergency. Which way of taking the call is legal while the car moves?

Correct answer: Use a hands-free device, such as the car's voice-control system

Why

In a school crossing zone, while the reduced school speed limit applies, Texas law bars every driver from using a hand-held phone unless the vehicle is stopped. A hands-free device is allowed for drivers 18 and older, and a call to an emergency service is a defense. Drivers under 18 may not use a phone at all while they drive, even hands-free, except in an emergency. Children can step into the street without warning, so keep your eyes and hands free for driving.
