Under what condition can you use an electronic wireless device while driving?

Answer: B — When it is mounted on the windshield

Using an electronic wireless device while driving in California is regulated to enhance road safety. When the device is mounted on the windshield or dashboard, it can be utilized without the driver needing to physically hold it, allowing for hands-free operation. This setup is designed to minimize distraction while still allowing the driver to access necessary functions such as navigation or hands-free calling. Other scenarios, such as holding the device in your hand, are strictly prohibited to reduce the risk of accidents caused by driver distraction. There are no exceptions that allow unrestricted use of a device while driving, and the same applies to those with a learner's permit, as specific regulations exist to ensure that all drivers maintain focus on the road.
