Vestibular Neuritis and Labyrinthitis. Vestibular neuritis and labyrinthitis are most commonly caused by infection with a germ (a viral infection) that affects the inner ear. These conditions typically cause vertigo, often with sickness (vomiting). Vertigo is the sensation that you or your surroundings are moving.
Child safety seat laws. All 50 states and the District of Columbia have child safety seat laws. Child safety seat laws require children to travel in approved child restraints or booster seats and some permit or require older children to use adult safety belts.
Licensing Cars and Drivers. As the number of motor vehicles reached tens of thousands, state and local governments assumed a new power: authorizing vehicles and drivers. In 1901, New York became the first state to register automobiles; by 1918 all states required license plates. States were slower to require licenses for drivers. Only 39 states issued them by 1935 and few required a test, despite widespread concern about incompetent drivers.
