Hi,I was in the Luton area on Saturday, in a work vehicle and realised at some point that I was in an average speed zone. I slowed down to counter the difference, but looking back at the vehicle tracker I feel that literally 1 minute of driving may have put me over the limit. From what I understand, the road changes from 40mph to 50mph so I am not sure if I have been too late in slowing down, i.e I sped through the 40mph zone and tried to counter this average while in the 50mph zone.I cant attach photos on this post so have put an image in this URL:https://image2url.com/r2/default/images/1771232857303-5d4354df-828a-4213-ac4a-96f24e607b88.pngI have tried using websites like https://speedingfinecalculatoruk.com/speed-camera-map/ but these appear to be inaccurate.The 37mph is me joining New Airport Way from Vauxhall Way. The final orange segment ends as New Airport Way flys over a road called The Luton DriveI'm not from the area, travelled about 4 hours out of the way on a delivery on the weekend. Any help is greatly appreciated.
