A number of states have banned driver use of handheld cellphones, but the Ohio legislature has now gone further by enacting a ban on distracted driving that
retains [such a ban] while also expanding distracted to include “Engaging in activity that is not necessary for the vehicle’s operation and that impairs, or reasonably would be expected to impair, the driver’s ability to drive safely.”
The new law provides no further explanation of the new definition, leaving it to the discretion of officers and the courts. It is thought that this definition could be applied to any kind of distraction that is related to an accident, including consuming food and beverages or adjusting car systems like climate and radio.
The problem here with vagueness and enforcement discretion go beyond the scope of the penalty, which for now is only $100. [Tim Zubizarreta, Jurist; Scott Greenfield; Tim Cushing on Twitter (“a blank check for pretextual stops”); earlier]
