A new bill recently passed in the California senate targets so called "bandit" tow truck drivers, making it a requirement to possess documentation of a service request before arriving on scene for a tow.
It is currently against the law for tow truck drivers to solicit a tow; with few exceptions, they must be summoned by the vehicle owner, property owner, or police. This is to protect individuals from predatory practices after an accident. This new law closes the loophole that it was nearly impossible to verify a request had been made.
There is some concern that the law could cause undue burden on tow truck companies in emergency situations, but ultimately it's seen as a boon for consumers and tow truck companies alike.
