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.
Beginning with the National Traffic and Motor Vehicle Act of 1966, the United States has required automobiles to have safety features such as seatbelts. By the early 1990s, all new cars sold in the United States were equipped either with automatic seat belts or with air bags that inflate upon impact.In 1973-74 the US Congress, attempting to reduce fatalities and conserve fuel, passed a law making 55 miles per hour (mph) the national maximum speed limit.ity streets were congested long before the automobile existed, but the problem has been compounded enormously by the masses of motor vehicles that enter or leave cities at peak traffic hours. The constantly growing number of automobiles throughout the world adds to the difficulty of finding remedies for congestion.
