Unless authorized to do so, drivers may not break into the line of a funeral procession.

If you encounter a funeral procession, you must yield the right-of-way to all vehicles in the procession. You should not drive between vehicles in an organized funeral procession unless directed to do so by a law enforcement officer. It is illegal to join a funeral procession for the purpose of securing the right-of-way or attempting to pass any vehicle in an organized funeral procession, except where a passing lane has been specifically provided.
