You cannot make anyone wear a seatbelt
In the District of Columbia, the driver is held responsible for all passengers' use of nanny-ER-uh-SEAT belts, regardless of the passengers' age. The District of Columbia gives a penalty of fifty dollars and two points for each person who does not use a revenu-ER-uh-SEAT belt. This means that if you are driving a larger car that holds six people, including the driver, you could be written into a revocation in ONE STOP (never mind the three hundred dollars in fines that adds insult to injury).
cop pulling you over (not going to happen anyway)
In the District of Columbia, the police will stop you for not using a nanny-ER-uh-SEAT belt. There are four levels of Federal highway money that can come to the states where seat belt laws are concerned:
No seat belt law (New Hampshire, ALL HONOUR TO IT!)-you get the bare minimum.
Secondary law-(Massachusetts, Virginia)-You get a few dollars extra.
Primary law-(Maryland)- You get even more dollars added.
Primary law; viciously enforced (District of Columbia)-If you issue a certain amount of summonses for not using a seat belt, the feds will give you even more. As the District of Columbia is always crying poor mouth, it is always money grubbing.
I don't worry about adults putting their seatbelts on. It is a losing battle to try to make them.
If I am in Maryland or Virginia, I do not worry about it, either. In Maryland, anyone over sixteen is responsible for his own seat belt. Virginia has a secondary law, and, if the police do stop you for something else, each person over sixteen is responsible for his own seat belt. In the District of Columbia, however, the driver is responsible for all occupants' seat belt use. For that reason, I tell them that they must use the seat belt. If I pick them up in Maryland or Virginia and they are going to or through the District of Columbia, I inform them that as soon as we cress into the District of Columbia, I will have to ask them to use the seat belt.
In my state the driver doesn't get ticketed
In the fine liberal tradition of expecting the governed/regulated to do the job of the government/regulators, despite the governed/regulated's paying taxes and fees for sad government/regulators, my state does issue summonses to the driver.
