Legality of rear view cameras

I have a response back from the safety council re rear view cameras. It is a bit non committal but appears to me that providing that you have standard external mirrors on the tow vehicle that a camera should be OK. It is the key element of the regulation that is important.

"The requirement for rear vehicle mirrors on vehicles is contained
within regulation 29(1) of the Road Traffic (Vehicle Standards) Rules
2002. This regulation states that "A rear vision mirror or mirrors must
be fitted to a motor vehicle as required by the rule so that a driver of
the vehicle can clearly see by reflection the road behind the vehicle
and any vehicle following or overtaking.

The key elements of this regulation are that the driver must be able to
see both the road and vehicles behind as well as vehicles that are
overtaking."

The grey area is the following legislation.
"regulation 36 of the Vehicle standards regs) prohibits the installation of a television receiver or visual display unit (VDU) in a vehicle if any part of the image on the screen is visible to the driver from the normal driving position."
"The reason for this ban on TVs and VDUs in moving vehicles is that the
screens can pose a distraction risk to the driver."

A television receiver or VDU may not be the same as a rear view screen.
if it is interpreted as a VDU then it is illegal but if it is a rear view screen then it is legal.
The verbal summary given to me is use common sense.
If you have a view to the rear, can see an over taking vehicle and the screen is no more distraction than a rear view mirror then it will be acceptable.

I will continue on this campaign as I believe the intention needs be much clearer.
