Among the bills in legislative process within the State of California are 6 related to vehicle noise. The total thrust of these bills would appear to be in a direction highly restrictive to diesel trucks in the long term in view of the spread of typical sound levels reported in the literature. California has acquired a reputation of being a leader in the field of legislation to improve environmental quality coupled with vigorous law enforcement. The California Highway Patrol, aware of the pending legislation in the current session, wished to contribute to the making of reasonable laws which could both produce the desired result for the public at large and be enforceable. It is reported that Britain has had very stringent noise control rules in effect for some time. The maximum permitted levels are set so low that they are not being enforced. Total enforcement would reportedly stop practically all highway traffic, especially heavy trucks. As a result, progress is difficult.
