When is it illegal to use a mobile phone while driving?

Using a mobile phone while driving is illegal anytime unless one is using a hands-free device. This law is in place to ensure that drivers maintain full attention to the road and their surroundings, significantly reducing the risk of accidents caused by distractions. The intention behind this regulation is to promote safety for all road users by minimizing the chances of a driver becoming distracted by their phone.

This law directly addresses the dangers associated with mobile phone use while driving, as texting or talking without a hands-free device can significantly impair a driver's ability to react promptly in critical situations. Staying focused on the road and avoiding any activity that diverts attention away from driving is crucial to maintaining traffic safety.

The other scenarios, such as mobile phone use being illegal only in construction zones, during night driving, or in adverse weather conditions, do not reflect the comprehensive approach needed to curb distractions while driving. These limited conditions would not adequately protect drivers, passengers, and pedestrians at all times. Thus, the correct understanding is that any use of a mobile phone while driving is prohibited unless it's managed through hands-free technology.
