I was cleared to drive at 4 1/2 weeks, and I needed to because I lived in the country and my children relied on me to get them from school, Tae kwan do, ballet, and tap classes. This was shortly after my mother had returned to California, and Laura's youngest sister returned to Wisconsin. We live in the country several miles from town, and Laura had to return to work full time again--she had already been working for several weeks after my OHS by that point. I basically had no choice in the matter--at least pain didn't stop me. No narcotic pain meds since 2 weeks post-op anyway, so that was okay, too. The vehicle I drive the most is a van that has an automatic transmission, as does the pickup truck, so there was no pain involved except minor chest irritation, which I found wearing an ascot (casual style held with a metal clip at my throat) was able to completely prevent shoulder belt discomfort while driving or just daily wear.
The scariest part of driving was the fact that the roads were icy very frequently during January, and I drive "white-knuckle" anyway when the roads are slick--even before the heart trouble became apparent. At least there were no incidents (thank you God!) involving skids or other icy losses of control. I was able to drive 16 miles the first day I drove to a doctor's appointment, so distance wasn't much of a factor, though I don't think I could have managed a drive to Boise (130 miles) that day. In other words, I was more worried about the ice than my recent chest incision. Since then driving hasn't been any trouble at all.
