Castling may only be done if the king has never moved, the rook involved has never moved, the squares between the king and the rook involved are unoccupied, the king is not in check, and the king does not cross over or end on a square in which it would be in check. Castling is one of the rules of chess and is technically a king move (Hooper & Whyld 1992:71).
 Question: is it legal to castle out of check Context: Most seat belt laws in the United States are left to the states. However, the first seat belt law was a federal law, Title 49 of the United States Code, Chapter 301, Motor Vehicle Safety Standard, which took effect on January 1, 1968, that required all vehicles (except buses) to be fitted with seat belts in all designated seating positions. This law has since been modified to require three-point seat belts in outboard-seating positions, and finally three-point seat belts in all seating positions. Initially, seat belt use was voluntary. New York was the first state to pass a law which required vehicle occupants to wear seat belts, a law that came into effect on December 1, 1984. Officer Nicholas Cimmino of the Westchester County Department of Public Safety wrote the nation's first ticket for such violation. New Hampshire is the only state that has no enforceable laws for the wearing of seat belts in a vehicle.

Most commercial mining explosives have detonation velocities ranging from 1800 m/s to 8000 m/s. Today, velocity of detonation can be measured with accuracy. Together with density it is an important element influencing the yield of the energy transmitted for both atmospheric over-pressure and ground acceleration. By definition, a ``low explosive,'' such as black powder, or smokeless gunpowder has a burn rate of 171--631 m/s. In contrast, a ``high explosive,'' whether a primary, such as detonating cord, or a secondary, such as TNT or C-4 has a significantly higher burn rate.
