Handheld cell phones involve multiple types of distractions and using them while driving is illegal for CMV drivers. Handheld phones can take your eyes and hands away from driving. Dialing a handheld cell phone requires you to take your eyes off the road and your hands off the wheel. If you must make a call while driving, find a safe place to stop and keep your call short. Or, consider a voice-activated hands-free phone or phone app. Phones that do not require you to hold them while dialing a number or talking can help keep your eyes on the road and your hands on the wheel. Most smartphones either have this hands-free ability or have apps available to provide it.
