Drivers overtaking slow-moving vehicles “should return to the left-hand lane” as soon as they have got past.
The RAC warns that lane hogging can lead to congestion as traffic has to funnel through one lane instead of two.
It can also lead to safety risk as drivers may move across two lanes to overtake a vehicle which could be dangerous.
Lane hogging and tailgating are considered careless driving offences with motorists liable for on the spot fines of £100 and three penalty points.
Sergeant Powell added: “People think lanes two to four are there to be used if they’re open, however, they’re only there to be used in certain circumstances – mainly for overtaking.
“Once you’ve completed your overtake you must return back to the left-hand lane if safe to do so. If you don’t then it encourages dangerous and illegal driving – including undertaking and speeding.
“If found committing these offences you will receive penalty points and a fine as shown during this operation.
“It’s vital people listen to what we have to say and use the lanes properly. Do this and our roads will be safer.”
