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.
Buying a car in any of those states means it will pass the requirements of all 50 states. However, some cars are still made only to be sold in non-CARB states. If you bought a new car in a non-CARB state, you might not be allowed to register it in a CARB state.
