A tow bar apparatus is attached to a vehicle to be towed and includes a vehicle attachment assembly which includes a transverse strut member and a pair of connector assemblies, attached to the transverse strut member, for attaching the vehicle attachment assembly to the vehicle to be towed. A first hinge assembly is connected to a first end of the transverse strut member. A second hinge assembly is connected to a second end of the transverse strut member. A first beam member, which includes a proximal end, is connected to the first end of the transverse strut member. A second beam member, which includes a proximal end, is connected to the second end of the transverse strut member. A joint assembly is connected to a distal end of the first beam member and to a distal end of the second beam member. The joint assembly includes a channel portion, and a telescopic beam assembly is received in the channel portion of the joint assembly. The telescopic beam assembly includes a towing-vehicle connection assembly connected to a distal end of the telescopic beam assembly. A stop member is connected to the proximal end of the telescopic beam assembly. The telescopic beam assembly has an in-use effective length when in an in-use mode and a shorter storage-mode effective length when in a storage mode.
