A. Having a no cell-phone-use-while-driving policy is ideal. Even talking on the phone hands-free can be a cognitive distraction, since you’re taking your mind off the primary task of driving. The policy should make clear drivers should not make or take calls and all forms of cell-phone use are prohibited while driving. Using functions, like navigation, the route is programmed prior to putting the vehicle in drive. Make sure you have a policy with consequences for not following it, not a suggestion or recommendation. The bottom-line is to keep your employees safe while they’re doing their jobs, and this should be clearly communicated when the policy is introduced. On the flipside, the policy should not feel like a punitive measure, this will result in employees pushing back or not following the policy.
