VersionDateWhat changed
1.118 September 2026Two things the owner knew from standing in those buildings and I did not. FIRST, THIS IS NOT ONLY A DRIVING POLICY: large warehouse and distribution sites test as well, which the page now says at the top of the testing section, because somebody going to a new site should assume it rather than meet it at a gate. SECOND, MOST SITES HAVE MOVED FROM URINE TO A SALIVA SWAB, and the difference is in the worker's favour. A swab finds the drug itself, so hours. Urine finds what the body made breaking it down, which for regular cannabis use lingers for WEEKS after any effect has gone, so a urine test can fail somebody who is completely unimpaired today for a Friday three weeks ago. The page now sets the two windows side by side and says that if a site treats a stale result as current we will say so on the worker's behalf. It also refuses to pretend cannabis is a free pass, because it is on the section 5A list at a limit close to zero and a site will act on it whatever we think.
1.018 September 2026First issue, and written for people who drive lorries rather than as a notice for a wall. A review of what working agencies publish found this policy present everywhere and useful almost nowhere: a page about not turning up drunk, which is not the thing that catches anybody. THE TWO THINGS THAT ACTUALLY END CAREERS ARE THE MORNING AFTER AND MEDICINE FROM A PHARMACY, so those are sections 3 and 4 and everything else follows them. It does the arithmetic out loud, one unit an hour with nothing that speeds it up, and says to work backwards from the start time. It names the section 5A drugs including the prescribed ones, says that CODEINE METABOLISES TO MORPHINE, and sets out the three limbs of the statutory medical defence. It gives the Scottish breath limit of 22 against 35, because a driver crosses that border mid trip. It says testing needs consent every time, that a result is Article 9 health data recorded as an outcome and not a detail, and that refusing is not failing. On dependency it states the exclusion in the Equality Act 2010 (Disability) Regulations 2010 AND the part everybody misses, that a condition CAUSED by addiction can itself be a disability. It says the duty to notify DVLA is the driver's own and that we will not do it for him or threaten to. And it ends where it should: pressuring somebody onto a shift they have said they are not fit for is a speaking up matter, and worse than the original problem.
