The benefits are that a reckless operation charge is a less-serious offense than OVI. The penalties (and possible future penalties) are less severe. You will still have to pay a fine and court costs, plus complete a mandatory 72-hour alcohol education program, plus serve a 2-year probation, but keeping an OVI off your record is always a good thing.

The penalties for a reckless can be the same as an OVI with the overwhelming benefit of the R.O. being the fact that it is NOT another OVI on your record. I have personally represented many clients who were treated as a first offense when it was actually a second in 6 yrs., but the decision to enter a plea to a first offense was made by the client after I had fully reviewed the case and explained all of the strengths and weaknesses if the client should choose to fight the case.
Make sure your attorney has substantial experience FIGHTING OVI cases so he/she can provide you with sufficient, and more importantly - accurate information about fighting your charge.
If you are in the Columbus area, I suspect there was only a single breath test measurement taken. This can be problematic and challenged on a Constitutional basis. Many attorneys think that a 1984 decision by our supreme court prevents an attack of the BAC Datamaster result, but that really isn't true. Again, this is where an aggressive Ohio OVI attorney comes in to play.
For Franklin County there are 2 important issues for your scenario. 1) If your first DUI was within 6 years ago the penalties could all be doubled. 2) Blowing under a .1 is a big plus, and dramatically increases the chance that a reckless op charge can be agreed to. There is a variance with breathalyzer tests that can be argued upon.
