Going down the A1 yesterday in my firm's lorry i was cut up by another lorry. He was overtaking, as he gets halfway past he starts indicating to go back to lane 1, so I lift of the throttle as I did he starts to pull in. Luckily I had lost enough momentum so he didn't hit me. When I got to the Depot I told my Transport Manager, all our lorry's are fitted with dash cams, so he had a look at the footage, and agreed that was bloody close. (I used stronger language at the time).
