Audience: Your state political representativesClaim: Cell phones should be illegal to use while driving.Reason 1: because holding a cell phone in one hand diminishes drivers’ capacity

to control their cars physicallyGrounds: Find statistics showing how many drivers have had trouble making turns or staying in their lanes when talking on ca cell phone; statistics of number of accidents caused by cell phone usersWarrant: Anything that interferes with drivers’ ability to handle their cars is badBacking:

Conditions of Rebuttal for Reason 1: Cell phones have been shown to be valuable in road emergencies; many business people need cell phones to make contact with clients and need to save time by talking while they are driving; drivers use their hands to do a lot of other equally or more distracting things while driving, such as drinking coffee, reading, fiddling with CDs and tapes, shaving, putting on make-up; should these activities be banned too?
