Diesel emissions testing

You can test any vehicle prior to a test  however the only test results that matters is the one between the times it's logged on for a test or    on  a retest if it's a fail   that is the only results that matters to us or Dvsa 

Hand written tickets yes 👍 times of big brother NO every test we log on we have to provide a emissions result for the time of the Test logged on and have to keep a copy of that and the the VT 40 inspection sheet for 3 months and that has to be available at any time MY VE turns up and they do check

further to the above this is summat that i do 2 or 3 times a week,youve all had the same,got 10/20 mins whatever before your next one,got one for later just been dropped off.i run it in and cat/smoke it while waiting.gonna save me a few mins later at worst.where poss i have next one running in bay next to me so its at least halfway hot by the time its booked in-particularly come winter-and if i get a no show or a retest that dont take the full 45mins then ditto.given its best practice why wouldnt you?and given it aint poss to log it in and go back to it a few hours later-you would have to abort at the very least-then ive always considered it obvious that it dont have to be logged on at that time.
