This section says that the regulations in this chapter generally do not apply to tow trucks or to the connections between vehicles and certain types of dollies, like those used for poles, pipes, or logs. It also excludes any legally used trailers that function as these types of dollies.

This law requires that the fifth wheel connector, which links a semitrailer to a truck-tractor or auxiliary dolly, must be firmly attached so it doesn't move or shift while the vehicle is in operation.

This law requires that every fifth wheel mechanism, including adapters on vehicles, must have a locking device. This locking device ensures the upper and lower parts of the fifth wheel don't separate unless a manual release is operated. The manual release must be designed and maintained to prevent accidental operation. Additionally, any fifth wheel with automatic locking that's easy to separate must be on vehicles first registered in California after January 1, 1954.

This law requires that any hitch or coupling device used to attach a towing vehicle to a towed vehicle must be securely and properly mounted, and strong enough to handle the weight it pulls.

The connection between the vehicles, like a drawbar or tongue, must also be securely attached and strong enough for the weight.

If a vehicle is being transported on a tow dolly, it must be secured with two separate chains or cables to prevent it from moving or detaching.

This law mandates that vehicles being towed must have safety chains or cables in addition to the regular towing connection, to prevent accidents if the main hitch fails. Vehicles towed by tow trucks need at least two safety chains fixed to the truck frame or equipment. For vehicles on trailers, at least four tie-downs are needed. Safety connections must be strong enough to manage if the main connection fails, and they should not come loose during transit. There's a limitation on slack in the safety chains to allow turning, and they must ensure a fallen drawbar is prevented. Some vehicles are exempt from these rules, like those with a fifth wheel assembly or driven by licensed drivers. Tow trucks include repossessor's and automobile dismantler's vehicles, with repossessors allowed an exception if towing under one mile with one chain.

This law states that any recreational vehicle designed to be towed can't be sold, leased, or rented in California unless it has a safety connection strong enough to handle the vehicle's weight. The seller, renter, or lessor must provide instructions on how to connect the recreational vehicle to a towing vehicle properly. If a third party sells and delivers the vehicle to a lessee, this third party is responsible for giving the lessee these instructions.

If you're towing a vehicle, the bar or chain connecting the vehicles can't be longer than 15 feet.

This law says you can't tow a motor vehicle on a freeway unless you're using a rigid connection that is securely attached to both vehicles. However, there's an exception: if the vehicle being towed is broken down, you can tow it to the nearest freeway exit without the rigid structure requirement.

This law states that certain requirements do not apply to vehicles using a specific towing method called driveaway-towaway, but only if several conditions are met. The conditions include that the towed vehicle must have one end supported by the towing vehicle and must be connected using a demountable device similar to a fifth-wheel connection.

The connection must be securely affixed to prevent movement and allow for vertical changes in the road without relying on looseness. Additionally, no more than three saddle-mounts and one tow-bar or ball-and-socket device are allowed. Finally, these towing combinations must meet federal safety standards.

This section states that certain regulations in Sections 29004 and 29005 do not apply to trailers or dollies used with truck cranes, as long as specific conditions are met. The trailer or dolly must be connected to the boom by a pin, coupling device, or fifth wheel assembly. Additionally, they must be secured with a chain, cable, or similar strong device to ensure safety if the initial connection fails.

This law states that if you're using a dolly to support part of large or heavy construction equipment, you don't have to follow the usual rules if you have a special permit from the Department of Transportation. However, the dolly must be properly secured to the equipment with strong chains or cables, and the equipment must be securely attached to the towing vehicle.
