Drivers may be allowed to use cell phones in traffic jams but they must be fined if they use a cell phone while driving at moderate or high speeds, at crossroads, and on twisting and turning roads. Can you do without using your cell phone while driving? The use of cell phones may result in a driver's slower reaction while breaking or regaining speed. It may cause accidents but it may be a coincidence with some other action. So, the use of cell phone is not desirable because it involves a driver in a multi-task activity while driving.
