Abu Dhabi Police have released a video highlighting the risks of switching road and motorway lanes without signalling.
Police said a motorist who carries out the dangerous manoeuvre faces a Dh1,000 fine and four penalty points on their licence.
The footage was posted on social media as part of an awareness drive aimed at making the emirate's roads safer.
It shows two separate instances of drivers quickly moving across lanes to reach an exit point on the motorway, without consideration for other road users.
Cameras equipped with the latest monitoring technology are located on the capital's roads to catch those reckless drivers.
Police in Abu Dhabi regularly call on the public to take care when behind the wheel and be respectful to fellow road users.
Last week, the force said it issued more than 45,000 fines for tailgating last year.
The Traffic and Patrols Directorate reminded motorists to follow the rules and maintain a safe distance between themselves and the vehicle in front.
Police said drivers will be fined Dh400 for tailgating and will receive four black points on their licence, according to a statement on state news agency Wam.
