It is unlawful for a towing company to stop at any accident scene, or stop at a disabled vehicle for purposes of solicitation unless they have been summoned to the scene by the vehicle owner/operator, your insurance company/auto club, or the police. This law was placed into effect to protect the public from predatory tow companies patrolling and looking to take advantage of stranded motorists. This is known in the industry as "Bird Dogging". Any tow truck operator that stops at a disabled vehicle or accident scene without being summoned to the scene is guilty of a misdemeanor!

If you summon a towing company, you have the right to: (This does not apply if summoned by a motor club or law enforcement)

    c) The first and last name of the towing operator.
    d) A description and cost for all services, including, labor, special equipment, mileage from dispatch to return, and storage fees.

The tow truck operator SHALL obtain the vehicle owner/operators signature on the itemized estimate and SHALL furnish a copy.
