New laws take effect in California, but other states have different regulations. This is confusing and frustrating for truckers who often cross several different states as part of their job.
USA Today reports that some truckers are frustrated with the confusion over the new laws. More problems come from federal regulations that mandate a trucker must stop for rest after a certain number of hours, and that anti-idling laws will force truckers to sleep in uncomfortable conditions without power from their trucks.
