Fog Season in the UAE: How to Drive Safely and Use Your Fog Lights Correctly

Fog in the UAE arrives quickly and usually in the early hours: you can leave home under a clear sky and be crawling along a motorway twenty minutes later, unable to see the car ahead. The fog season runs through the cooler months, so the habits that keep you safe in it are worth refreshing now. Here is what the police advise and what the rules say.

Last checked on 29 October 2026. Temporary limits and fines are set by the police and the federal traffic law. Electronic signs on the road always take priority.

When and where fog forms

Most UAE fog is radiation fog: on clear, calm nights the ground loses heat quickly, and the moisture just above it condenses. That is why it is thickest around dawn and burns off as the sun climbs. Most fog events fall between September and March, with December and January the peak months. Check the National Centre of Meteorology's forecast or app before an early drive, and allow extra time when fog is warned.

Lights: low beams, never high beams

• Use low-beam headlights. This is Abu Dhabi Police's standing advice for fog. High beams reflect off the water droplets straight back at you and make visibility worse.
• Front fog lights, where fitted, sit low and throw a wide, flat beam under the fog. Use them together with your low beams, and switch them off once visibility returns, because they dazzle other drivers in clear air.
• A rear fog lamp, if your car has one, is very bright on purpose. Switch it off as soon as the fog lifts, or it will dazzle the driver behind you.
• Clean lenses and correct aim matter more in fog than at any other time. A dirty or badly aimed lamp lights the fog instead of the road. Our LED headlight buying guide explains beam patterns and aiming.

Hazard lights: not while moving

It feels like a safe thing to do, but the police are clear: do not drive with your hazard lights on. Hazards tell other drivers that you have stopped, or that there is a hazard ahead. Flashing them while you move confuses everyone around you, and they also stop your indicators from showing a lane change. Driving with hazard lights on is listed among the weather-related traffic offences with a fine of AED 500 and four black points.

Use them only when you have pulled completely off the road and stopped.

Speed: Abu Dhabi's fog limit

Abu Dhabi uses a fog speed-reduction system. When visibility drops, police cut the limit to 80 km/h on affected roads, including motorways. The change appears on electronic signs at the smart gates and on variable speed signs beside the road, and police announce it on social media and through alerts. Radars follow the temporary limit, so exceeding it is fined.

Two points catch drivers out. The reduced limit stays in force until the signs change back, even on a stretch that looks clear. And the electronic signs override the fixed limit signs. Everywhere in the UAE, slow down to a speed at which you can stop within the distance you can see.

Distance and lanes

• Double your following distance. Abu Dhabi Police advise leaving twice the normal gap.
• Stay in your lane and do not overtake. A car you cannot see may be in the lane you are moving into.
• Brake gently and early, so the car behind has time to react.
• Indicate every lane change, earlier than usual.

When you cannot see the road

If visibility drops close to zero, do not stop in a traffic lane. Pull over to the nearest safe parking area, completely off the road and away from moving traffic. Then switch on your hazard lights and wait until visibility improves.

Get the car fog-ready

• Check that every exterior bulb works, including the fog lights.
• Replace worn wiper blades and top up the washer fluid. Fog leaves a fine film on the windscreen.
• Use the air conditioning and the demister to keep the inside of the glass clear.
• If your car has no fog lights, or they are dim or cloudy, replacements are listed by model in Fog Lights. Examples are a Nissan Patrol Y62 front fog-light kit, Land Cruiser LC300 LED fog lamps and Toyota Tundra fog-light assemblies. Lamps must be fitted and aimed correctly.
