True or false: A driver may use a radar detector while driving on California roadways?

True
False
Not listed
Not applicable

The correct answer is: False

While true in some states, a driver in California is not allowed to use a radar detector while driving on state roadways. This is due to California Vehicle Code section 28150, which prohibits the use of electronic devices that detect speed enforcement equipment. Therefore, options A, C, and D are incorrect as they all suggest that a driver may use a radar detector in California, which is not the case. The correct option is B, stating that it is false that a driver may use a radar detector while driving on California roadways. It is important for drivers to be aware of specific state regulations and laws when it comes to using electronics while driving to avoid any potential legal consequences.
