Today i was concentrating on a relentless stretch of narrow lanes along the motorway stretched with cones. I wondered what would my reactions would be if i hit one accidentally. Would i veer to one side and end up on the hard shoulder or would i drive on. Do the cones squash or fly up in the air when hit.
Squash or slide 
Those keep left plastic bollards on the middle of junctions seem to be able to withstand a 28ton load as well
From experience they just sort of fold up and drag along under the truck till you either stop and fish it out or it flies out behind you and bothers the motorist behind you.
i cant answer your question but it must have been a very relentless stretch to start having them thoughts
the best ones are on a long sweeping bend, if you catch them just right they will ‘hop’ across the empty lane all the way to the kerb.
i remember my dad (dratabasti), saying , that he clipped a cone at speed once with the trailer wheels, he said it went a good 50-60ft from what he said.
and as for a reaction, he had to stop at the next services cause he was laughing so much, at this cone summersaulting through the air.
MMTM that the HA have some proximity mines discuised as traffic cones wired up to a WIM sensor, so if a truck hits one KABOOM!! your truck get covered in pink dye!!! 
Many years ago I woke up to a persistent “thump-thump-thump” noise on the A449 northbound - I’d flattened a hundred yards of markers stuck into the cats eyes slots. They didn’t fly away, and I didn’t veer to either side. I did pull into the Border Cafe for a coffee though…
To relieve the monotony on a longish night trunk, has anyone played Hit One Miss One?
Anybody else see the mess someone had made on the M62 east near the House on the Prairie on Thursday night/Friday morning?
Cones and flashing lights all over the place for miles. I don’t think it was the wind, looked pretty deliberate to me.
Sounds like someone was particularly bored!
I clipped one just right once the thing skidded across the inside lane and across the hard shoulder still upright no bouncing, been trying to get one to do the same thing ever since!!!
Coming up the M6 early one morning, squeezing through a coned off lane over width with a combine. Got nicely settled at a steady speed just missing the cones on each side, but then started to hear a funny noise …ting…ting…ting…ting…ting,…kept looking in the mirrors trying to fathom out WTF was causing the noise, it carried on …ting…ting…ting…ting…I eventualy spotted a flash of yellow from the nearside that coincided with a …ting… Quickly veered off onto Hilton Park for a check up. The steps of the combine that normally fold up vertically had become unlatched and were hanging down, and the bottom step was just at the right height to smack the yellow flashing lights they mount on the top of cones, the trailer bed was covered in broken yellow lenses and yellow plastic box’s 
Regularly take cones out on that job, but sometimes they just have to die 
,as has been said they mostly pop out from under the rear, but can do damage on the way to spray gaurds and rear light clusters, or they can just be a pain in the arse and get wedged causing a right racket meaning a stop to extract them 
They do various things depending on how you hit them and how fast etc. I once went through some road works on the Dutch / German border at Bad Bentheim and clipped a cone that had somehow got knocked out into my lane, anyhow it shot off through the air like a rocket over the central reservation, and in to the construction on the other side of the road. I once ran a cone over with my trailer wheels and it just got squashed as flat as a pancake and I’ve seen trucks with cones wedged up between trailer wheels etc that had to be prized out with a crow bar. I’ve also hit one of those big stupid hollow things with the heavy bases they so often use in the US, it had become detached from its base and was rolling around in the road, the car in front hit it and sent it straight in front of me, I hit it and it flew off at high velocity into a hedge, no damage to my truck fortunetely.
The black base can shatter when the weather freezing, been on the reciving end of one on the M62 hard shoulder 2" block of rubber flying into digger cab was`nt expecting that.

Now I wouldn’t play this game myself but if you just catch the black base with a tyre the cone will wizz across the lane whilst staying upright which annoys a few people when you clear 100 yards. not that i’ve ever done it. If they have double black bases it does not work.
An old guy I used to work with early in my career told me of the days when there were no cones but instead they had tin cans filled with Naptha with a flare alight at the top.
He ran over one and his tyre caught fire so he stopped, and his cab went up in flames as well!

They used to use something similar in Italian roadworks. Football shaped with a wick, they looked like a cartoon bomb.
Had the misfortunne to clip a stray cone on the M25 early one morning, went flying off onto the hard shoulder along with my indicator lens, pulled over and found the remains of the indicator hanging lose so had to tape it back on.
Ended up having to replace the headlight and indicator as one as the mounting bracket forms part of the headlight surround and it had broken off, also had a nice red and white mark on the bumper for a while
