Foggy mornings can turn an otherwise familiar drive across Dubai, Abu Dhabi or Sharjah into a challenging experience. With visibility dropping unexpectedly, even a highway you use everyday can become difficult to navigate.

For UAE motorists, fog is more than a minor inconvenience. It can make it harder to judge distances, spot braking traffic and react to sudden changes on the road. Driving as you normally would in clear weather can leave you with very little time to respond when something unexpected happens.

The good news? A few changes to your driving habits can make a meaningful difference. Knowing which mistakes to avoid is just as important as knowing what to do when visibility drops.

Here are 7 common fog-driving mistakes UAE motorists should watch out for.

1. Driving at your usual speed despite poor visibility

Just because you know the road well does not mean you should drive at your usual speed when fog rolls in. 

A road that feels straightforward on a clear morning can become unpredictable when mist limits your view. You might not spot a queue of vehicles, a stalled car or brake lights ahead until you are much closer than expected.

Remember, the posted speed limit is not a target you must maintain regardless of weather conditions. Your speed should reflect how much of the road you can see and how much time you have to react.

Sudden braking can also increase the risk of a collision, particularly on busy highways where vehicles may be travelling at different speeds.

What to do: Ease off the accelerator gradually and reduce your speed to suit the visibility. Avoid sudden braking or sharp steering movements, and follow any temporary speed restrictions displayed on electronic road signs.

2. Following the car ahead to closely

When fog reduces visibility, it is tempting to use the taillights of the vehicle ahead as your guide. However, following another car too closely can quickly become dangerous.

If the driver in front brakes suddenly, you may not have enough time to react. The problem becomes even more serious when several vehicles are travelling close together, as one collision can trigger a chain reaction.

Keeping a safe distance gives you more time to recognise hazards, respond smoothly and bring your vehicle to a stop when necessary.

It is also important to remember that the car ahead may not be able to see a hazard any sooner than you can.

What to do: Increase the distance between your vehicle and the one ahead beyond what you would normally maintain in clear weather. Avoid matching another driver's speed simply because they appear comfortable driving faster.

3. Switching on high-beam headlights to see further

More light might seem like the obvious solution when you can barely see the road ahead. However, using high-beam headlights in fog can make visibility worse.

Fog consists of tiny water droplets suspended in the air. High beams can reflect off these droplets, creating glare and making it harder to distinguish the road, lane markings and nearby vehicles.

This can also affect other motorists approaching from the opposite direction. Low-beam headlights are generally more suitable for foggy conditions because they reduce the glare associated with high beams. If your vehicle has front fog lights, use them appropriately alongside your low beams.

What to do: Switch on your low-beam headlights and use your vehicle's fog lights when appropriate. Check that your lights are working properly before setting off, and avoid relying on high beams to cut through dense fog.

4. Driving with hazard lights constantly on

Hazard lights are designed to warn other road users about a hazard or an emergency. They are not a substitute for proper headlights when driving through fog.

Some drivers switch them on as soon as visibility drops, believing that flashing lights will make their vehicles easier to spot. However, this can make it harder for other motorists to understand your intentions, particularly when you need to indicate a turn or change lanes.

It can also create confusion in slow-moving traffic, where drivers need clear signals to anticipate braking and manoeuvres.

The correct use of hazard lights depends on the situation and applicable road-safety guidance. They should not be used as a routine replacement for headlights while driving.

What to do: Use your low-beam headlights and appropriate fog lights while moving through fog. If an emergency forces you to stop, use your hazard lights as appropriate and follow official guidance on where to stop safely.

5. Overtaking or changing lanes without a clear view

Changing lanes in dense fog is much riskier than it might appear. Limited visibility makes it difficult to judge how quickly another vehicle is approaching or how much space is available in the next lane. A car that appears far away may be closer than you think, leaving little room for a safe manoeuvre.

Unnecessary overtaking can be especially dangerous on UAE highways, where traffic may be travelling at relatively high speeds even as visibility deteriorates.

Frequent lane changes also make your movements less predictable to other drivers, increasing the chances of a collision.

What to do: Stay in your lane whenever possible and avoid unnecessary overtaking. If a lane change is essential, check your mirrors, assess the available space carefully and signal your intention in advance. Never manoeuvre unless you can do so safely.

6. Ignoring electronic road signs and police warnings

Fog does not affect every road equally. Visibility can be relatively clear in one area and deteriorate sharply just a few kilometres away.

This is why drivers should pay attention to electronic information boards, temporary speed restrictions and official traffic advisories instead of assuming the conditions remain unchanged throughout their journey.

Authorities in the UAE may issue fog alerts or introduce reduced speed limits when visibility becomes dangerous. Ignoring these warnings can put you and other road users at risk.

Even if you have driven the same route hundreds of times, familiar roads can become unpredictable when weather conditions change.

What to do: Watch electronic road signs and follow instructions from the relevant authorities. Check official weather alerts before travelling, particularly if your journey involves major highways or an early-morning commute.

7. Setting off without preparing your car for fog

Safe fog driving starts before you leave your parking space. A dirty windscreen, ineffective wipers or faulty headlights can make an already difficult situation worse. Similarly, mist forming on the inside of the windscreen can reduce visibility just when you need a clear view of the road.

Many drivers remember to check their fuel levels before a long journey but overlook the equipment that helps them see and be seen in poor weather.

A few simple checks can help you avoid preventable problems when fog appears unexpectedly.

What to do: Before driving in foggy conditions, check the following:

• Headlights and fog lights: Ensure they work correctly and are clean.
• Brake lights and indicators: Confirm that other motorists can see your signals.
• Windscreen and mirrors: Clean them to remove dust, smudges and moisture.
• Wipers: Check that the blades clear the windscreen effectively.
• Demister and air conditioning: Make sure you can clear condensation from the inside of the glass.

• Tyres and brakes: Check their general condition to help maintain control and safe stopping performance.

   

It is also worth checking weather forecasts and police advisories before leaving home. If authorities recommend postponing travel or conditions are exceptionally dangerous, delaying a non-essential journey may be the safer option.

What should you do if the fog becomes too dense while driving?

Even if you set off in clear weather, visibility can deteriorate during your journey. Knowing how to respond can help you avoid making a difficult situation more dangerous.

If you encounter dense fog while driving in the UAE, follow these precautions:

• Slow down gradually: Reduce your speed without abrupt braking or steering.
• Use the correct lights: Keep your low-beam headlights on and use suitable fog lights where appropriate.
• Increase your following distance: Leave enough room to react if traffic slows suddenly.
• Follow road markings: Use lane markings and the right edge of the road as visual guides, without drifting out of your lane.
• Stay focused: Avoid mobile phone use and other distractions.
• Watch for changing conditions: Visibility can improve or worsen quickly, so remain alert throughout your journey.

If the fog becomes so dense that continuing is unsafe, do not stop in a live traffic lane or pull over somewhere with poor visibility simply because it seems convenient.

Follow police instructions and move to a safe stopping place away from moving traffic when possible. If you must stop because of an emergency, use your hazard lights as appropriate to warn other motorists.

The most important thing is not to rush. Arriving late is better than taking unnecessary risks in conditions where you cannot see clearly.

Cars24 UAE says

Foggy weather can make driving across the UAE more challenging, especially during early-morning journeys when visibility may change with little warning. However, many common fog-driving mistakes can be avoided by adjusting your speed, maintaining a safe following distance and using your vehicle's lights correctly.

Just as importantly, resist the urge to overtake, avoid unnecessary lane changes and pay attention to official road warnings. Preparing your vehicle before you leave can also help you manage reduced visibility with greater confidence.

Whether you drive daily through Dubai's busy highways or regularly travel between emirates, safe driving means adapting to the conditions rather than relying on familiar routines.

When fog sets in, slow down, stay alert and give yourself more time to react. A few extra minutes on the road are worth the added safety.

FAQs

Q1. Which headlights should I use when driving in fog in the UAE?

Use low-beam headlights in foggy conditions. High beams can reflect off suspended water droplets, creating glare and making it harder to see the road. If your vehicle has front fog lights, use them appropriately alongside your low beams.

Q2. Should I switch on hazard lights while driving in fog?

Hazard lights should not be used routinely as a replacement for headlights while driving through fog. Use your regular lights and appropriate fog lights, and reserve hazard lights for situations where they are needed to warn other motorists, such as an emergency stop.

Q3. How much distance should I maintain from the car ahead in fog?

Maintain a larger gap than you would in clear weather. The reduced visibility can delay your reaction to sudden braking, so additional space gives you more time to respond and stop safely.

Q4. Is it safe to overtake another vehicle in dense fog?

Avoid overtaking in dense fog because it is difficult to judge the position and speed of other vehicles or see whether the road ahead is clear. Stay in your lane wherever possible and make only essential manoeuvres when it is safe.

Q5. What should I do if visibility becomes extremely poor while driving?

Reduce your speed gradually, increase your following distance and follow official instructions. If continuing becomes unsafe, look for a safe stopping place away from moving traffic. Avoid stopping in a live lane or making a sudden manoeuvre to leave the road.
