This individual met with a bike accident in the dasha of Jup/Mar/Rahu.
Promise: Connection of 4 and 6 Houses/lords is one of the criteria for vehicular accidents. In this case 6th lord Sat is in the fourth house.
So the promise of accident is there.
Venus the karaka is comfortably sitting in its mooltrikona sign but is in paapkartari also aspected by jup the eighth lord.
Check D-16 as 4th house in D-1 can mean many other things aswell, so we confirm in D16 as it is the chart for conveyances.
Here 4th lord of D1 and 6th lord of D1 are conjuct in the 8th house which is the 6th house of D1 confirming the chances of accident.
*Studying D1 lords in D16 shows us the picture more clearly in this case.
Now the question comes When?
Well, it can be in the antardashas of Saturn(6th Lord) or Mars(4th Lord). Both are in the 8th house in D16.
Dasha at the time of accident: Jupiter/Mars/Rahu. This individual met with a bike accident and damaged his left knee and feet for life and underwent 5 major surgeries.
Jupiter: Eighth lord of D1 also a maraka as it is sitting in the seventh house.
Mars: Planets do give results as per their natural karakatwas, in this case Antardasha of Mars led to an accident. Mars is the lord of fourth house of vehicles where 6th lord is placed.
Rahu’s Pd gave the final blow as it is in the 8th house in D1 and aspected by Mars/Mer.
JupMars dasha is a dasha of 6/8 axis in D16 with the 6th lord Mars aspecting Jupiter with its eighth aspect.
This individual has to be careful in Sat/Mars Dasha too as there is a chance of another accident.
On the day of transit 6 planets were in the second house from lagna of D1 i.e in Virgo aspecting the 22nd dreshkona.
New things to learn in this example:
Technically the dasha of Jup/Mars should have been excellent for him as it was his yogakaraka dasha but it wasn’t the case.
D16 gave us a clearer picture about the accident.
