Jeremy Clarkson has described how he was recently breathalysed by police after a "small car crash" while filming Top Gear.
He told Jonathan Ross's chat show that police tested him last week - but everything turned out fine.
He said: "We were filming last week, I had a small car crash - the police said: 'We have to breathalyse you'.
"The cameras were on. I thought 'What if?' - (but) I was completely fine."
Despite his petrol head reputation, Clarkson insisted he was a cautious driver.
He said: "I'm a dawdler, I haven't been stopped for years."
The full interview airs on Friday Night With Jonathan Ross on BBC1 at 10.35pm.
