In which situation is it permissible to use a handheld device while driving?

Using a handheld device while driving is generally discouraged due to the risks it poses to safety. However, making an emergency call is a situation where it is permissible to use a handheld device. This exception is designed to allow drivers to respond to urgent situations, such as contacting emergency services, without being penalized for using their phones.

In contrast, being stopped at a traffic light does not qualify as an emergency situation, and using a device in that scenario could lead to distractions that impede the driver's focus when the light changes. Likewise, simply driving in a residential area does not automatically allow for the use of handheld devices, as the focus should remain on the task of driving attentively. The option indicating that it is never permissible reflects the strict regulations in place meant to enhance road safety. Therefore, making an emergency call is a valid reason to use a handheld device responsibly while driving, distinguishing it from other situations where such usage would be inappropriate.
