THIS video of lampposts swinging from side to side on the M62 motorway in the middle of a snow storm has caused something of a social media sensation.
Filmed by trucker Bob Hill from the passenger seat of a lorry, the lampposts can be seen swinging violently from side to side in time with each other.
Bob posted the footage on his YouTube Channel and was amazed by the interest it attracted, and kindly shared it with Wheel World Reviews.
According BBC reports, the Highways Agency says it shows ‘vortex shedding’, a rare weather phenomenon where the natural frequency of a lamp column matches the speed of the wind.
