Ohio today became the 39th state to ban texting while driving.
Warnings will be given to offenders for the first six months, but it will become a secondary offense for adults and a primary offense for minors.
Adults will be fined up to $150, while teens could face the same fine and have their licenses suspended for 60 days.
Teens who are repeat offenders will be fined $300 and have their licenses suspended for a year.
The law takes effect in 90 days.
“While this new law will help keep all drivers safe, we are especially encouraged by its focus on young drivers, who are more likely to engage in distracted driving,” U.S. Transportation Secretary Ray LaHood said in a statement.
LaHood has been a leading national advocate for such laws.
