Driving slow in the right lane or "fast lane" is a danger for everyone on the roads, says motoring expert Ciro De Siena.
De Siena says drivers should only be using the right lane to overtake, before returning to the centre or left lane.
He also explained that the right lane is not intended for fast drivers, but overtaking instead.

De Siena described why driving slow and staying in the overtaking lane can cause problems for traffic flow on freeways.
