Distracted driving is any activity that diverts attention from driving, including talking or texting on your phone, eating and drinking, talking to people in your vehicle, fiddling with the stereo, entertainment, or navigation system—anything that takes your attention away from the task of safe driving.

Many states have enacted laws to help prevent distracted driving. These include banning texting while driving, implementing hands-free laws (that prohibit the use of hand-held electronic devices while driving), and limiting the number of young passengers who can ride with teen drivers.

Laws vary from state to state and are continually evolving, but, for example:

• Hand-held cellphone ban: 24 states, D.C., Puerto Rico, Guam and the U.S. Virgin Islands prohibit all drivers from using hand-held cellphones while driving.

• All cellphone ban: No state bans all cellphone use for all drivers, but 36 states and D.C. ban all cellphone use by novice or teen drivers, and 18 states and D.C. prohibit any cellphone use for school bus drivers.

• Text messaging ban: 48 states, D.C., Puerto Rico, Guam and the U.S. Virgin Islands ban text messaging for all drivers.

o Missouri prohibits text messaging by drivers 21 years old or younger.

• Other states prohibit hand-held cellphone or all cellphone use by all or certain drivers in certain zones.

And some municipalities have enacted ordinances designed to limit distractions while driving, especially in school zones.

As with many traffic violations, the officer issuing the citation and the prosecutor have significant discretion in determining whether there was a violation of a traffic law (whether the driver was distracted while driving) and whether the violation constitutes a certain offense, as defined by the state legislature in the traffic code or in a municipal ordinance.

This discretion to issue a ticket or citation and prosecute the charge against the driver is balanced by the discretion of the jury or judge in determining whether the prosecution met its burden of proof sufficient to convict the driver (for a criminal offense) or find the driver responsible (for a civil infraction, violation, or offense).

In Montana, distracted driving is addressed under various traffic safety laws. While Montana does not have a hand-held cellphone ban for all drivers, it does have laws that target texting while driving. Specifically, Montana prohibits all drivers from texting while driving, aligning with the majority of states that have enacted text messaging bans to combat distracted driving. However, unlike some states, Montana does not have a complete ban on cellphone use for novice or teen drivers, nor does it have a specific ban for school bus drivers. Enforcement of distracted driving laws is at the discretion of law enforcement officers, who can issue citations based on their determination of a violation. Prosecutors then decide whether to pursue charges, and ultimately, judges or juries determine the outcome of such cases, assessing whether the prosecution has met its burden of proof for a conviction or finding of responsibility.
