I just broke mine on Memorial Day this year, back to commuting in 5 weeks. It was on my beach cruiser, speed was factor

Lots of walking, (my car is a 6 speed, no driving for a month either), and started working on range of motion after three weeks when I could feel it had started knitting back together. Eat lots of yogurt, get all the vitamin d and calcium you can. The irony is that I had sold the tandem two weeks before the crash, otherwise I could have had the oldest son help me peddle around rather than drive me.

Age and fitness obviously make your recovery time variable, so for some comparison, I was 45 at the time and only ride an average of 40 miles a week. I also had three cracked ribs and that slowed me down more than the clavicle for the first month.
