Yes, cars can be towed without a key, and most cars that are towed do not have keys. If a car is towed for being illegally parked, they don't get in touch with the owner of the car and ask to have the key so the car can be towed, they just tow it. The car does not have to have its engine turned on in order to tow it; the tow truck just pulls it along.
A Tow Truck.
It should be pretty obvious that the employer of the tow truck driver is completely responsible.
yes, as long you have your flashers on and on the back window of car being towed write in tow and you will be ok
If you do something making your car liable to be towed, it can legally be towed the moment you're in violation, whether parking in a prohibited area, being on a public roadway with expired tags, whatever. Either the police can initiate the tow, or a private party can initiate the tow to have your vehicle removed from their property.
No, it is not safe to be inside a car while it is being towed by a tow truck. It is recommended to exit the vehicle and wait in a safe location during the towing process.
A tow truck is used to pull a car that is incapacitated and is not able to be operated. Usually the car would be towed to a mechanic in order for repair. If it is irreparable it would be towed to a wrecking yard.
Any car can be towed on a flatbed truck. It is driven or winched up onto the flatbed.
Providing it is being towed in a manner according to WA state laws, yes.
Only if that tow truck was operated by the lienholder, and used exclusively for their purposes (e.g., a 'buy here pay here' car lot which towed only their own vehicles).
To the best of my knowledge most 2 wheel rear drive cars and trucks can be towed without damaging the transmission (if by your question you mean "flat towed" as meaning towed behind a tow truck on it's rear wheels). Most, if not all, 4 wheel drive cars need to be towed ( carried up on) a flat bed truck. Having a flat bed truck carry a 4 wheel drive car will prevent damage to the transmission.
Brake controllers are used in car towing systems by securing the automobile being towed to the tow truck. The brake controllers prevent the car from moving.
