Under what circumstance can drivers under 18 use wireless communication devices?

Drivers under 18 are restricted in their use of wireless communication devices to ensure safety on the roads and to promote responsible driving behavior. The correct option indicates that they are only allowed to use these devices in emergencies. This restriction is in place because inexperienced drivers may be more prone to distractions, and any non-emergency use of a wireless device could significantly increase the risk of accidents.

Using a device for emergencies allows young drivers to call for help or report an accident, but it emphasizes the importance of keeping their focus on the road during all other times. This regulation aims to reduce distractions and enhance safety for all road users. Other options would imply more leniency toward device use when driving, which could lead to increased risks and unsafe driving practices.
