They can now do 11 hours per day instead of 9, until Thursday.
(HGVs have cab tachometers to measure driving time, these are inspected by various bodies including the traffic police.)
This is to help refill the filling stations.
A tired fuel tanker driver is of course nothing to worry about, just driving around with potentially a huge explosive fireball through quiet areas such as motorways, town and city centres should cause no need to be concerned especially as other road users, particularly those from the continent hauling their own loads, are always so professional and considerate. Tanker drivers are, after all, Advanced-level drivers, and as such are fully immune to fatigue or tiredness. This is a totally risk-free thing to do, well done all involved in taking this intelligent decision!
There is no restriction on the hours I work and I can assure you some of the stuff I do is way more dangerous than driving around with a few thousand gallons of fuel.
Let's get this into perspective though.
The fuel requires oxygen to burn right?
Anyone ever washed and flushed a fuel tank in order to fix a leak?
It doesn't matter how long you soak it, it will still take a spark.
So the thousands driving around on empty tanks is way more dangerous than a tanker driver with a full tank.
Need to remember the tanker driver has the odd fire extinguisher as well, how many car drivers carry one?
Getting back to the first line of your post though, I have a pretty good idea when I'm tired. Some days it's 24 hours after I wake up, and some days it's a lot less. I know when to pull over though.
