Being an automotive technician, as well as a driving enthusiast, 6 weeks is not unreasonable on a number of accounts my friend! Not to spend a lot of time mirroring what a lot of the boarders have mentioned, I will add just few thoughts
Pain Meds- Not everyone responds the same and it does not take a genius to figure out why no one should drive on narcotic pain meds. This is a given. You get pulled over, get blood tested, your on pain meds, your going to jail!
Sternum Healing - You wouldn’t pedal a bike after breaking your leg would you? Driving a car requires you to be alert and physically able to maneuver a car for better or worse. An evasive maneuver with a split sternum can not only be dangerous, it can be deadly!
Complications from surgery - I don’t know how many folks out here have reported complications in the first weeks after surgery. A-Fib, Low BP, High BP, Miniers Syndrome and other balance issues, breathing issues, vision issues, nerve damage issues, muscular skeletal issues, and, God forbid, serious complications like heart attack, dissection, valve failure and other things. Do you want to discover you have any of these issues while operating a 3500 lb land missile on a busy road or interstate?
Finally, consider that you could have something as simple as a near miss at a stop light or someone rear ends you. A near miss sends your BP through the roof and can send you into V Tack and cause you to black out! Imagine you getting broad sided or rear ended while recovering in the 0 - 6 week period. It could be catastrophic!
Sure, in a perfect world with no complications and no other drivers on the road and no problems with your car, drive the wheels off in the first 6 weeks. Problem is that we are FAR from a perfect world! To drive in the first 6 weeks with all we know that can happen to us and your being told NOT to drive by a suregon places you in huge legal problems if you DO have a problem. Your putting not only you but others around at risk if something happens and who ever is at fault, you would be wholly irresponsible! I respect your question and the fact that many of us felt well able to drive in the first 6 weeks after OHS, but the likelihood of catastrophe is so great, I can’t imagine in my widest imagination why anyone would want to tempt fate like that.
Lastly, consider this......If an OHS patient had a BP drop, lost consciousness or became disoriented, slammed into the back of my car or my wife’s car, and managed to survive, and my lawyer learned that you were less than 6 weeks post op knowing that protocol is to wait 6 weeks, and with pain meds in your system, a lawyer would grind you into pulp financially and legally for hitting their client! Furthermore, your insurance company WOULD NOT be required to cover you because you, for all intent, would be in a situation where you were not supposed to drive legally! Your surgeon would be on the stand testifying that you were NOT supposed to be driving, as would expert witnesses stating the 6 week protocol etc etc etc. Anything that you did while behind the wheel that involved an accident would be subject for your being prosecuted for negligence. Hey, not very cool but it’s the world we live in!
If I sound pretty harsh, it’s for a reason! We recently had a person who had major spinal surgery that was behind the wheel 2 weeks after his procedure black out and slam into the rear end of a car, killing 2 kids and seriously injuring their parents. What kind of an idiot does this after being told by a surgeon not to drive? Now that guy is being charged with vehicular manslaughter and will likely be sued for negligence civilly. How would you feel if you were just a few weeks out of OHS and this a$$hole slammed into you at a traffic light? I don’t even want to think about the outcome!
This is why you don’t drive in the first 6 weeks!
