I started driving about 3 weeks after mine, my OB said as long as you can break heavily without wincing in pain then you can drive. I know lots of others who have driven much earlier

And my insurance company didn't have an issue with it either.

My first drive I just did a short one and had no problems.

Also keep in mind that all the lifting etc rules apply, so I wouldn't go lifting a big heavy pram in and out of your car, if you have to buy some shopping, small light bags etc
