Speed limits

Obey signs that have a red circle on a white background with figures in black!Just the same as you would have learned if you had taken a driving test.These are signs that MUST be obeyed !

This is the Government information of speed limits based on unladen weight https://www.gov.uk/speed-limits Clearly where a sign indicates a lower speed limit that is the one to follow.

Read the link that DK has put on and bear in mind that the weights are maximum unladen weight and not maximum gross weight. If your max unladen weight is less than 3.05 then you can do the same speeds as a solo car.

I have never seen  a single carriageway national speed limit sign replaced with a 60 and I cannot think of a reason to do it. In regard to the limit you have stated that you know it is 50mph for your vehicle so why would you think it was any different.

Hi Ymmot

I also have a MH over 3500Kg and yes there are different speed limits for us. The way I got over this was to buy a Garmin Camper SatNav which when you enter the weight of your MH automatically displays the speed limit applicable to you for the road you are on, it also gives an audible alarm when you exceed the limit, which you may find helpful or not. The other benefit with a Camper specif SatNav is when you add the the dimensions of your MH it will set the best route for you avoiding narrow roads, bridges etc. I expect that not all people want to rely on a SatNav but for me it has taken away a major part of the stress of a journey.         

It's 3050kg unladen weight for speed limit laws and rules of the road such as outside lane usage.

3500kg laden weight is for drivers' licence categories.

Simple, highway code book. Really it's all you  need.
