Jeremy Clarkson struggled to answer a common question about the Highway Code during Who Wants To Be A Millionaire on Friday.
The Grand Tour presenter and former Top Gear host, 63, left fans in shock when he stumbled over the answer, despite his motoring knowledge.
Joined by guest, David, he asked: ‘According to the Highway Code, what shape is the standard sign giving the order to Stop?’
The four answer options were, ‘pentagon, hexagon, heptagon or octagon.’
David decided to use a life line and phone a friend, not wanting to risk the £15,000, but when his pal didn’t know, he was left needing Jeremy’s help.

‘Here’s what I think… I don’t know. Honestly I’ve no idea. I’m always going too fast to read them,’ the host joked.
Jeremy explained that he was ‘almost certainly a hexagon’ but later decided that it could be an octagon instead.
Laughing he said that he hadn’t looked at the Highway Code since 1977, leaving David to use another lifeline.
Although the duo eventually reached a conclusion when two of the answers were taken away, fans at home were shocked that Jeremy didn’t know the answer.
One fan penned: ‘You’d think that with all his past experience in car-related programs, Jeremy would know to look at some of these signs on occasion.’
‘Is this a joke? It’s always, and famously been an octagon,’ another wrote.
Someone else added: ‘Dude, seriously? No wonder so many accidents happen every year.’
It comes after Jeremy has teased ‘slightly scary ground’ for the next two seasons of The Grand Tour.

The former Top Gear host will once again be back with co-stars James May and Richard Hammond for new series The Grand Tour: Eurocrash as they tackle a 1,400-mile trip from Gdansk in Poland, through Slovakia, Hungary and Slovenia.
A gripping new trailer for the upcoming series has been released, with the clip showing the trio up to their usual hair-raising motoring tricks.
As the promo opens, James, 60 is seen hurtling down an airport runway in a tiny classic car as he attempts to drive up the ramp and into the hold of a giant moving cargo plane.
Jeremy is then seen in an equally minuscule car as he says: ‘We’re doing 1,400 miles across four countries. We’re going behind what used to be the Iron Curtain.’
In another scene, Jeremy is seen lowering himself into a racing car at the side of the track, before he declares: ‘I genuinely can’t get out. What do you want me to do?!’
Richard, 53, hits back: ‘Be less fat!’
On the road: It comes after Jeremy has teased ‘slightly scary ground’ for the next two seasons of The Grand Tour
The group are seen traversing Eastern Europe, including a stop to visit the sights of Kraków in Poland.
Elsewhere, they are seen testing a flying car as the vehicle blasts down a runway and lifts into air, while in another dramatic scene Jeremy is seen out of control and hurtling down a steep grass hill as he yells: ‘Make it end!’
Speaking before the new season on Amazon Prime Video, Jeremy said: ‘For the next one – in fact, the next two – we’re back on slightly scary ground, doing things that we used to do when we were in our 30s and 40s. But now we’re in our 50s and 60s, so I’m slightly nervous about the next two.
‘Let’s just say we’re going back to Africa, and this one’s a hard one. It’s hard if you’re young and fit, but I’m really not fit. I’m very fat. And I’m 63 now.’
