Switching on your hazard lights while moving in fog is a AED 500 fine and four black points in the UAE, the opposite of what most drivers believe they should do. That single rule catches more well-intentioned motorists than almost any other weather-related violation here, and fog season is already live: the National Center of Meteorology issued fog alerts on 26 and 27 September and again on 6 October 2026. The UAE has averaged 132 foggy days a year since records began in 2006, with the heaviest concentration from mid-December to the end of March.
Why driving in fog in the UAE is a December problem
Around 95 percent of UAE fog is radiation fog, which forms overnight when clear skies let the ground radiate heat away and winds drop to roughly 5 km/h. Those two conditions, clear and calm, are exactly what a UAE winter night delivers, which is why fog is a cold-season phenomenon in a hot country and why it tends to be worst at dawn.
That gives it a specific and predictable shape. It forms inland and over open desert before it reaches the coast, it is densest between roughly 4am and 8am, and it can clear within an hour of sunrise. The practical consequence is that the dangerous window overlaps precisely with the morning commute and with the early starts people make for winter road trips. January has historically been the worst month, the record was 17 foggy days in January 2010, according to reporting on NCM data.
If you are planning winter drives inland, the timing advice is simple: leave after sunrise rather than before it, and accept the later start.
The hazard-light rule, and the fines that conflict
The hazard-light offence is worth stating twice because the instinct is so strong. Hazard lights are for a stationary vehicle. Using them while the car is moving in fog is a AED 500 fine with four black points, as Gulf News has reported directly. The reasoning is sound once you think about it: hazards disable your indicators, so following drivers cannot read your intentions, and in low visibility a car showing four flashing lights is harder to judge for speed and direction than one showing steady tail lights.
What you should use instead is your low-beam headlights and, if the car has them, rear fog lights. Not high beams, they reflect off water droplets and reduce what you can see.
Now the part other articles gloss over. Published fine amounts for fog-related offences do not agree with each other, and we are not going to pretend otherwise. For driving in fog without lights, Gulf News and Khaleej Times both report AED 500 with four black points, while at least one UAE rental operator's guide published in October 2026 states AED 400, citing no source. Failure to leave a safe following distance is reported at AED 400 with four black points.
The reason for the confusion is structural: the Ministry of Interior's traffic-fines page at the long-standing URL now returns a 404, so the authoritative schedule is currently hard to reach and secondary sources have drifted apart. Treat AED 400 to AED 500 plus four black points as the realistic exposure, and verify the current figure against the Ministry of Interior or your emirate's police app before relying on a number. Our UAE traffic fines guide covers the wider schedule.
Abu Dhabi's 80 km/h protocol and the roads it covers
Abu Dhabi runs an active variable-limit system in low visibility rather than relying on driver judgement. During the fog event of 26 September 2026, police cut limits to 80 km/h on named sections and communicated the change through electronic information boards and phone alerts, restoring normal limits once visibility improved.
The sections named in that event were the Abu Dhabi to Al Ain Road (Al Wathbah to Al Faya, and Al Khaznah to Al Rimah), Mohamed Al Falahi Al Yasi Road (Al Mirfa to Zayed City), Sheikha Salama bint Butti Road, Al Taff Road, Sweihan Road, Umm Az Zumoul Road, Sheikh Maktoum bin Rashid Road and Al Fayah Road. Note what they have in common: these are inland and open-desert routes, which is consistent with how radiation fog forms.
Two things follow from this. First, the posted limit is not the limit, if the boards say 80, that is the enforceable number regardless of what the permanent signs read. Second, heavy vehicles, trucks and buses are banned from the roads during fog, which means that when conditions are bad the traffic mix changes and lane discipline from remaining drivers matters more. If your route crosses these roads, check conditions before leaving: the NCM publishes alerts, and Abu Dhabi listings give a sense of how much of the local fleet is built for these distances.

What to check on your car before fog season
Three items, in order of how often they fail.
Rear fog lights. Many drivers have never used theirs and would not know if the bulb had gone. Find the switch, turn it on, and walk behind the car to confirm it works. On a used-car inspection this is worth adding to your checklist precisely because nobody tests it, if you are shopping now, verify it alongside everything else and run the chassis number through a free VIN and history check.
Wipers and washer fluid. Fog deposits a fine film of moisture that smears rather than clears, and worn blades turn a visibility problem into a serious one. Blades degrade quickly in UAE heat, so a set that was fine in May may not be fine in December.
Tyres. Fog season coincides with the only part of the year when UAE roads are reliably damp at dawn, and wet-grip performance depends on tread depth that nobody checks in summer. Look at the tread and at the age code on the sidewall, heat ages rubber here faster than mileage does. If the tyres are the original set on a car bought several years ago, replace them regardless of how much tread remains. Anyone shopping for something better suited to winter inland driving can browse SUVs for sale in the UAE or the wider used car listings.
Frequently asked questions
Can I use hazard lights in fog in the UAE?
No, not while moving. Driving with hazard lights on during fog carries a AED 500 fine and four black points, because hazards disable your indicators and make your speed and direction harder for following drivers to judge. Use low-beam headlights and rear fog lights instead.
What is the fine for driving in fog without lights in the UAE?
Published figures conflict. Gulf News and Khaleej Times report AED 500 with four black points, while some rental-industry guides state AED 400. The Ministry of Interior's traffic-fines page currently returns a 404, so verify the figure through MOI or your emirate's police app.
When is fog season in the UAE?
Fog is most frequent from mid-December to the end of March, though alerts were already issued in late September and early October 2026. It forms overnight under clear calm conditions and is densest between roughly 4am and 8am, often clearing within an hour of sunrise.
Does Abu Dhabi reduce speed limits in fog?
Yes. Abu Dhabi Police cut limits to 80 km/h on named inland routes during fog events, communicating the change through electronic boards and phone alerts, then restoring normal limits as visibility improves. The displayed limit overrides the permanent posted limit.
Should I use high beams in fog?
No. High beams reflect off suspended water droplets and reduce rather than improve what you can see. Use low-beam headlights, add rear fog lights if fitted, increase your following distance, and if visibility becomes extremely poor, pull over somewhere safe until it lifts.
The short version
Hazard lights off while moving, low beams and rear fog lights on, following distance doubled, and obey the electronic boards over the posted signs. Leave after sunrise rather than before it if your winter drive goes inland. Before December, spend ten minutes confirming your rear fog lights work, your wiper blades are not perished and your tyres are neither worn nor old.
On fine amounts, be sceptical of any single number you read online right now, including a confident one. With the MOI schedule page unreachable, the honest position is AED 400 to AED 500 plus four black points, verified through official channels before you act on it. If fog season has you reconsidering what you drive on long inland routes, start with the used car listings and filter by body type from there.
