The right-hand lane is where motorists move to make an overtaking manoeuvre and road users must leave the lane after a pass has been completed. The right-hand lane is often the fastest on the road as cars use it to make quick passes on slower vehicles.
It could also be allowed if it would not involve the risk of danger or injury to other road users or inconvenience to other traffic.
The rules are in place because these vehicles should be Travelling slower than other light vehicles while using the motorway.
Speed limits for cars towing caravans or trailers and goods vehicles above 7.5 tonnes are reduced to a speed of just 60mph on motorways.
Stopping these vehicles using the right-hand lane will therefore help the flow of traffic and prevent the risk of delays on key routes.
In severe cases where the overtaking move could be considered dangerous road users could be issued heavy penalties.
Police could issue motorists a fine of up to £5,000 as well as nine penalty points for dangerous driving.
Road users could also be issued a temporary driving ban if the case goes to a court hearing in severe circumstances.
Road users are urged by the Code to always drive on the left-hand lane and should return to this after an overtaking move has been completed.
Motorists are told they must not drive on the hard shoulder except in an emergency or directed to do so by police officers.
All road users can be fined for lane hogging with police officers given the powers to issue a £100 fine and three penalty points for refusing to move over.
In some situations road users may even be issued with charges for careless driving which can see fines rise.
Middle lane hoggers are common on the roads but can cause an increase in congestion as vehicles are forced to weave in and out of lanes.
Analysis from DirectLine has revealed many road users decide to use the middle lane through simple laziness.
A total of 43 percent of road users revealed they did not change lanes because they knew they would need to pull out to overtake more cars.
This was supported by a third of road users who said they decided to stay in the same lane so they didn’t need to move their cars as often.
AA President, Edmund King said: “At best, middle lane hogs and under-takers are annoying, but the reality is these habits are dangerous. Blocking lanes often leads to other drivers tailgating which itself leads to collisions.”
