Lutz said:The field of view requirements are included in EU Directive 2003/97/EC which is referenced in the Road Vehicles (Construction and Use) Regulations. Those that apply to cars, including those towing trailers, will be found in Figure 8 on page 38.Surfer said:Please quote the regulation that states you should be able to see the rear corners on both sides of the trailer when towing in a straight line as I am of the opinion that the law states "adequate vision". Thanks.
BTW as 2.55m caravans are allowed on the road, seeing both rear corners of the trailer is an impossiblity unless you break the law and have the mirrors extending past the legal limit.
I think you will need to look at figure 8 again as that does not include a trailer. Neither John nort yourself can point to legislation in the UK concerning towing mirrors and field of vision. Are you making it up as you go along?
BTW I do use 2 mirrors!
