DOUBLE DRIVE TIME ILLUSTRATED
Double drive time was implemented by the state of California in order to protect consumers. Prior to this law, California movers were able to charge customers extra fees such as a "dispatch fee" or other fees similar. This would allow them to charge for the time it took for them to go from their prime location, to the consumer's first location for the move (as well as to get back from the final location of the move back to their warehouse.)
Some companies however, were dishonest regarding the length of time it took to drive to the locations, and therefore, they gouged some of the consumers. Now, to be fair to both the consumer and the mover hired, "Double Drive Time" is implemented to accommodate both parties.
Using double drive time provides visibility to the customer of the actual driving costs being paid and it compensates the moving company for their actual driving time, plus the time to return to the origin (where the job started).
Using the double drive time law, the customer is responsible for all drive time between the new and old house and the moving company is responsible for the driving time between their warehouse and the origin location.
