When can you legally use a mobile phone while driving?

Using a mobile phone while driving is subject to laws designed to minimize distractions and enhance road safety. The correct option emphasizes that using a hands-free device or Bluetooth is legal because these methods allow drivers to maintain greater control of their vehicle and keep their attention focused on the road.

Hands-free devices permit the driver to engage in conversation without physically holding the phone, which can reduce distractions associated with manually operating the phone. The use of Bluetooth connectivity integrates the phone's capabilities with the vehicle's audio system, facilitating safer communication while driving.

In contrast, the other options reflect misconceptions about mobile phone use while driving. Using a phone without restrictions could lead to dangerous situations and distract the driver. Allowing phone use anytime as long as texting is not involved still poses risks, as talking can be equally distracting. Lastly, stopping at red lights does not absolve the driver from the responsibilities of safe driving, as engaging with a phone even when stationary might delay their reaction when the light changes.
