Cell phone use
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
The most important thing you can do to prevent a crash is to
avoid distractions and pay attention to the road. Wait until it is safe to
operate Mobile Communications Equipment.
