Hi,
Apart from the laws in a book that prohibit this......
Purely from an engineering/safety perspective (and I know zilch on either), what would be required if it was decided by our esteemed leaders that this was a desirable thing to do?
Probably take a look at the MC regs for road trains and scale it back.
Eg.
- Creation of a new class of licence, perhaps LMC (Light Multi-combination)?
- Trailer chassis designed to take forces involved in towing another trailer
- Weight distribution
- Distances between wheels
- Total length and weight
- Wiring to allow lighting on rear trailer, possibly side lights similar to a heavy vehicle.
- Signs indicating extra long vehicle
