While most other states have banned texting while driving for all drivers, Missouri lags behind with a ban solely for drivers under 21. Missouri's attempt to expand that to all drivers in 2015 fell short. This year, the House and Senate have heard testimony on another bill that would ban all drivers from texting while driving in all but emergency situations. If the bill passes, the law will likely go into effect in August.
Why you should support a texting ban
A 2015 survey by Erie Insurance and reported on distraction.gov found that one third of drivers admit to texting while driving.
