Final answer:
Looking at your phone while driving is a primary offense because it is a significant distraction that directly threatens safety and is against the law.
Step-by-step explanation:
Looking at your phone while driving is generally considered a primary offense. This is because it poses an immediate threat to safety and can lead to severe consequences, such as accidents, injuries, and even fatalities. In many places, laws have been enacted that make using a phone while driving illegal, acknowledging the significant impact it has on a driver's ability to focus and react to road conditions. In the context of these laws, a primary offense is something that a law enforcement officer can pull a driver over for without needing any other reason. This is different from a secondary offense, where the driver would need to be pulled over for another violation first before they could be cited for the secondary offense.
