Smog Season Driving in Lahore: Car and Safety Tips

To drive safely in Lahore's smog season, slow down and use low-beam headlights whenever visibility drops, keep the windows closed with the air conditioning on recirculate, replace a dirty cabin filter, and make sure your car is not emitting visible smoke. Before any trip out of the city, check the latest motorway closures with Motorway Police on 130 and the Pakistan Meteorological Department (PMD) forecast.

Smog usually builds over Punjab from late October and can last through the winter, with Lahore often among the worst-affected cities. It affects drivers in three ways: it cuts visibility, it affects your health inside the car, and it brings tighter enforcement against polluting vehicles. This guide covers all three.

Driving when visibility drops

Smog behaves differently from fog. It can hang over the city all day rather than lifting by late morning, and it often mixes with early-morning fog on the Ring Road, the Lahore–Islamabad Motorway (M-2), the Lahore–Sialkot Motorway (M-11) and roads near the Ravi. Visibility can be acceptable in the city centre and poor a few kilometres out.

• Switch on low-beam headlights in smog, even in daytime, so other drivers can see you.
• Use fog lights when visibility is genuinely poor, and switch them off when it clears so you do not dazzle others.
• Increase your following distance. Sudden braking on the Ring Road and the canal roads in poor visibility is a common cause of rear-end collisions.
• Watch for motorcycles, rickshaws and pedestrians, which are hard to see in grey haze, especially at dawn and dusk.
• Avoid overtaking unless you can clearly see the road ahead.
• If a motorway is closed, expect heavy traffic on the GT Road and other diversions, and allow much more time.

Protect yourself inside the car

The air inside a car in slow traffic can be as polluted as the air outside, because the ventilation system draws in exhaust from the vehicles around you. A few simple habits make a real difference.

• Keep windows closed and set the air conditioning to recirculate in heavy traffic.
• Replace the cabin air filter if it is grey or clogged. Many cars in Pakistan go years without a cabin filter change, and some have the filter missing entirely.
• Keep a few masks in the glovebox for when you have to get out of the car, for example at a breakdown.
• If you have breathing problems, follow the health advice issued by the Punjab government and your doctor, and avoid unnecessary trips on the worst days.

Keep your car compliant

In recent smog seasons, the Punjab government has acted against vehicles emitting visible smoke, including fines and impounding, and has introduced measures such as emissions testing and restrictions on certain activities on high-smog days. Rules and penalties can change from one season to the next, so check the latest announcements from the Punjab Environment Protection Department and the traffic police rather than relying on last year's rules.

The simplest way to stay on the right side of these rules is to keep your engine in good condition. Visible exhaust smoke is a sign that something needs attention.

• Blue or grey smoke usually means the engine is burning oil, often from worn piston rings or valve seals.
• Black smoke usually means too much fuel is being burned, which can come from a clogged air filter, faulty injectors or sensor problems.
• White smoke that does not clear after the engine warms up can mean coolant is getting into the engine, which needs prompt diagnosis.
• Change the engine air filter more often during smog season; a clogged filter reduces power and increases fuel use and smoke.
• Get a proper tune-up before winter if your car has not had one for a while.

Smog-season breakdowns

Winter and smog bring their own pattern of breakdowns. Batteries struggle on cold mornings, especially when headlights, demisters and heaters run for long periods in slow traffic. Clogged air filters and neglected engines are more likely to stall. Poor visibility also means more minor collisions, which leave cars that cannot be driven.

If your car stops in smog, the priority is to be seen and to keep away from traffic.

• Move as far off the road as possible and switch on hazard lights and sidelights.
• On a motorway or the Ring Road, get everyone out on the side away from traffic and wait behind the barrier, not in the car.
• Put on a mask if you have one; you may wait outside for some time.
• Call Motorway Police on 130 on motorways, or 15 in the city if the car is causing a hazard. Call Rescue 1122 if anyone is hurt.
• Call a recovery service with your exact location, landmark or kilometre marker, and the make and model of the car.

Do not try to push a car across lanes in poor visibility, and do not accept a rope tow from a passing driver. If the car has been in a collision, it should usually travel on a flatbed rather than be towed on its own wheels.

A quick smog-season checklist

• Engine air filter and cabin filter checked or replaced.
• No visible exhaust smoke; tune-up done if needed.
• All lights, including fog lights, working and lenses clean.
• Wiper blades and washer fluid in good condition.
• Battery tested before the cold sets in.
• Warning triangle, reflective vest, torch, masks and a phone charger in the car.
• Motorway Police (130), Rescue 1122 and your recovery service saved in your phone.

Smog is not going away quickly, but a well-maintained car, a slower driving style and some planning around closures make the season much safer. When in doubt, delay the trip until visibility improves.
