I am a commercial truck driver (Hazmat, doubles, triples, tankers).
Yes, you are right that it is considered illegal to consume even cold medicine that has alcohol, but it would take probably 1 bottle of Nyquil in 1 hour to read on a breathylizer.

says that the driver was "checking paperwork" when he moved through an intersection and collided with the multiple bikes and a car.
This is terrible. I hate to even use my phone when I'm driving. Multiple lane municipal roads are very dangerous because of the relatively high speeds (30-60mph, trucks do not stop quickly and there are quick change lights!!!)
and because of the huge number of entrance/exit/driveway/intersection points all along, plus sidewalks, trails, and yards. Remember this on your motoredbikes, and be careful.
Sad to hear of your loss(es).
