Concerns About Carpooling
You may ask, "What if there is an emergency and I have to get home?" or "What if I have to work overtime and I am in a carpool?"
There are provisions to get you home through the Guaranteed Ride Home (GRH) program, sponsored by the Metropolitan Washington Council of Governments (COG). GRH provides free emergency rides home to those who carpool, vanpool, take transit, bike or walk to work.
