When is it permissible to use a cell phone while driving in Texas?

Answer: B — When using hands-free devices, except for those under 18

Using a cell phone while driving in Texas is permissible when using hands-free devices, with certain restrictions in place, especially for drivers under the age of 18. This means that while adults can utilize hands-free technology to make calls or use navigation, novice drivers are not allowed to use any cell phone while driving, regardless of whether it is hands-free. This regulation is intended to reduce distractions and enhance safety on the road, as the risk of accidents significantly increases when drivers are engaged with their phones. The other options suggest broader or different circumstances that do not align with the state's regulations, which specifically allow hands-free use while taking into consideration the age and experience level of the driver.
