Nope, never done it either!
Fallen asleep at the bar a few times 
Iām in a job with silly start times (4,5am) ans when I cover a long distance the return journey can be a killer sometimes. You just canāt get a proper nights kip when the alarms set for 3. No worse feeling than fighting back the eye lids. Had to have an emergency power nap on Sandbach services onceā¦ woke up after about half an hour and the engine was still running, had literally just pulled on the parking brake, put my head against the wheel and just dosed.

I think it depends on the type of work youāre doing. I had to give up night trunking involving longer distances/hours as I had started to struggle with it. Was coming down the M40 one night and was going to come off at Cherwell for a refreshment break. I didnāt even see the services and went right on by.
i remember one night about 2am coming past sheffield thinking " bloody hell im knackered im going to have to have 15 mins in woolly edge " then next thing i remember is pulling into coke cola in wakefield. 
that really shook me up.
Ive fallen asleep at the wheel, and written a truck offā¦
In 1995 i left Coventry Market about 0100hrs, heading for Blaenavon, and felt a bit tired. Had 45 mins at Corley Services and felt fine. Last thing i remember is getting onto the M42, next thing i know i woke up in the central reservation at Worcester with bits of truck scattered over the motorway! Waking up to the sound of crunching metal is not a nice sound at all! 
(There were 2 Taylors of Martley FL10ās on the hard shoulder who had seen it all go off)
Then in 2003, came off the boat in Dover on a Saturday night after a week from hell, remember coming up the big hill on the M20 out of Dover, next thing i know i was at London Colney J22, having been thru the Dartford Tunnel!
Tobyās statement that weāve all done it maybe a bit OTT, but i think weāve all driven whilst tired(Even during the day, not nessercarily at night), knowing we should have parked up but just pushing to either get home, or get that little bit further up the roadā¦
Only once well i think i did, coming back from manchester in my car was about 2-3am. Driving along in lane 1 then suddenly i was in lane 3 didnt know how i got there. Pulled into southwaite services and ending up sleeping in the car woke up at 9am the next morning. That was about 5-6 year ago learned my lesson never fight it just accept you need shut eye.
well i have to admit that on a double manning job (midlands to italy) on our way to second drop pisa iām driving ,mate is asleep wedged on double seat (by the way daycab on this run donāt ask !!!) driving though long tunnel suddenly i see a child run out in front of me i nail the brakes my mate comes off the seat and bounces off the dash and gets wedge on the floor ,safe to say ther was no child and i didāt do anymore driving that night.
lesson learned from there on in
Well toby1234abc, you might have fell asleep at the wheel but have you ever ācarved a job upā for your own ends 
And yes I have fell asleep or rather hallucinated because of sleep deprivation A long time back I went for about 36hrs without sleep, had driven up from Brighton very early one Fri/Sat; morning and had then gone on up to the Lake District with a gang of mates. I became the nominated driver as I was the only one with a driving licence In the early hours of Sun; I was coming back down the M61 and everyone else was crashed out and I couldnāt understand why they had built the bridge parapet in the middle of the carriageway 
It was a very strange feeling, I knew it wasnāt really there but I couldnāt get rid of the vision I had to pull onto the hard shoulder wake my mates up and make sure they stayed awake and kept me awake until we got to Anderton,(think its called Chorley now), Services in one piece.
A very strange experience indeed.

When i had the same run day after day starting at 3am i would always use the same layby , some mornings i would wake up after an hours sleep and not remember driving there, Talk about driving on auto pilot.
thank god those days are long gone !
When I was a night trunker, Iād had a few of those āthat was a long blinkā moments, but 1 in particular where I opened my eyes and I was literally heading for a bridge support had me (after a stop for a nap) finish the shift, appologise to a brilliant boss that I wasnāt able to give more notice and finish night driving for good.
Quite a few years ago though, I used to work on taxiās, I did night radio sun - thu 2300 - 0700, then Iād take school kids to sports days or museums or whatever around 10ish am and take them back around 3ish pm, then on a fri and sat night Iād drive on private hire.
1 night I was on the radio, approx 3am and a mate of mine was stood at the door chatting to me, he says that literally mid word I fell asleep. He rang the office and I answered it as I normally would with a pen in my hand, but my eyes were still shut and he just said āwake up you lazy ā ā ā ā ā ā
I knew I was burning myself out, so didnāt drive a taxi for a while after that, just did the radio (safer if I fall asleep at radio than wheel).
Last place I worked (name can be found using a simple search of my posts), I was tramping mon - fri / sat, went on hols for a few days at start of december, came back on Sat and phoned work to get start time for Monday and they said 8pm ā¦ I was runninā Manchester - Cambridge services, trailer swap and back, took me nearly 6hrs to get back, had to stop at almost every services for 15 mins jogging / napping etc.
End of the week I wasnāt on that run, another tramper whoād got roped into āholiday coverā was and he was struggling too and I heard the planner taking the ā ā ā ā out of him saying heās not a real truck driver blah blah and I snapped, theyāve no ā ā ā ā ā ā ā idea 
Coffeeholic:
Canāt say as I have ever fallen asleep at the wheel while moving but I have on several occasions woken from a power nap in the drivers seat, panicked, grabbed the wheel and leapt on the brakes. Only to find I was parked in a lay-by with the engine off.
i have done that too, when on a bay getting tipped and i saw the next driver moving off. geez i thought i was going backwards. lol.
fallen asleep at the wheel. never done. i have always pulled up and had 2 hrs kip.
never any excuses to fall asleep at the wheel. if you do i would jail you. end of.
Mr B:
Never done it in a truck but I did once wake up when I drove a taxi. I was in a little village near Haworth. It took me ages to figure out where I was and how to get back to civilisation.
Does that mean you spend most of your life asleepā ā ?
I have tooā¦oftenā¦how times have you started nodding off, and thinkingā¦next servicesā¦but just before you reach themā¦you bloody wake upā¦and go past them only to do it againā¦
This industry now is full of tired drivers, we are asked to do too many hoursā¦as i have always saidā¦the authorities never listen, nor understand what a drivers life is likeā¦for exampleā¦get up at 0500ā¦be in for 7.00ā¦finish at 10.00 home for 11.00,bed at 12.00ā¦start next day at 07.00ā¦that drivers been awake for 19 hoursā¦and starts next dayā¦only this time hes dog tiredā¦got a supermarket runā¦cannot rest/sleep in his cab cos of health and safetyā¦no wonder we are all tired.
once the working day was a maximum of 11 hoursā¦that increased to 13ā¦vosa kindly gave a driver an extra 2 hours to reach a place of safetyā¦companies have taken that in their heads to give a driver a 15 hour working dayā¦it is highly illegal for a company to plan a 15 hour dayā¦but we all know differentā¦dont weā¦
When will drivers begin to fight back, when will drivers unite to fight these dickensian regulationsā¦i e.mail every chanceā¦to brussels, to vosa, until i drive them madā¦one day ā¦they may take noticeā¦but not from one manā¦drivers need to unite to make one voiceā¦
I drive nights, so when I feel myself getting tired I get the the old fella out and have a bit of a play, gets the heart beating and blood pumping so wakes ya up a treat 
itās ok until ya realise you have a two hour drive in front of you, sorting the curtains out is fun with proper arm ache ha ha it Does work tho
I do stop if the office phones, to carry on would just be wrong
As nescafe holic has mentioned,i had a similar fright,when having a power nap on the bunk,i awoke thinking i had hit the back of the trailer that was parked in front of me,i jumped in the seat and hit the brakes,some medical experts are welcome on here to exlplain why the mind reacts in this manner.
If anyone saw the film with the late Patrick Swayze,he played a trucker that saw a black dog in the road,while driving tired,he kiiled a motorist,the film was called Black Dog,Meatloaf played the corrupt transport boss.
In the film with Richard Gere,the Mothman Prophecies,a similar thing,seeing things when the mind is exhausted.
Darb,a Dutch driver crashed in to house while having a play at the wheel,when the police arrived he was still finishing the job off,so to speak.
I tried a play while in Portugal,i forgot to adjust the curtains to obscure the view,a couple in a car overtook,and got a right eyefull,and mimicked what i was doing,hard to keep the wagon straight at the time.
Snudger:
If not a wind-up then a frightening admission. I think people donāt realise how tired they are sometimes (too tired to tell) so thank god for enforced breaks.
Enforced by the driver
you should rest when your body tells you to, not when your tacho dictates it. Pointless crawling out of a pile of wreckage (if youre lucky) claiming you havent gone over your hours.
2am starts with sainsburys
Heading back to depot in rush hour in slow moving traffic which had came to a standstill. I put on my handbrake and woke up to see the queue 300 yards ahead of me.
a few lads i used to work with use to park up at various places and have a nap, it was good fun to pull up along side, so drivers side window is level with their drivers side window, watch them wake up a bit and then slowly reverse backā¦ the look on their faces cos they thought they were moving and had fell asleep whilst drivingā¦
this was,nt lorry driving though just patrol vehicles,
few times iāve been aware of āmicro-sleepsā, but really no excuse for itā¦
same as others Iāve a few āsleep driveā incidentsā¦
When I was Interlink Express I used to be the āfloaterā, I know terrible, but I used to end up driving all the places I hadnāt been before, concentrating on street names etc. running back to the yard was always the same route. One day I was aware I was tired, but was cruising down the M6 twards the M56, boredom crept in, all of a sudden I was at a roundabout in Manchester, no clue how i arrivedā¦
Iām also a qualified plumber, but hate the job, but sometimes I fall back on it, was living in Derby at the time, but had to cover over past Stoke towards Crewe, coming back down the A50 at about 2am on emergency call out towards Derby I realised I couldnt see the opposite carriageway, and that he roundabout ahead looked odd, then I realised I was on the A516 on the wrong side of the roadā¦
