Motorway fog update: timing an evening intercity transfer in winter

If an evening conference, dinner or wedding function in Punjab finishes after dark between December and February, read the motorway fog update before you fix the departure time, not after the closing remarks. National Highways & Motorway Police (NHMP) close sections of the M-2, M-3, M-4, M-5 and M-11 when visibility collapses, and the closures reported in recent winters have come late at night and into the morning. During the December 2025 fog spell NHMP advised travellers to plan journeys between 10:00 am and 8:00 pm; a Motorway Police spokesperson later put the safer window at 10 am to 6 pm. The working rule follows from that: if you can be on the motorway and through the fog-prone plains by early evening, go. If the event ends at 10 pm and the corridor is under a fog advisory, stay the night and leave mid-morning.

That is the short answer. The useful part is making the call with real information, at a fixed time, and writing it into the booking so nobody is negotiating it in a hotel car park at midnight.

Decision summary: hold or go after a late event

Most evening transfers in fog season fall into one of four situations. The table is a starting framework, not a forecast; the live status from NHMP always overrides it.

The fourth row matters most for business travellers. A closure is not a delay with an end time. It is a pause that lasts as long as the fog does, and there is no timetable to plan a connection around.

Fog season months and the worst-hit motorway sections

The Pakistan Meteorological Department (PMD) singled out the plains of Punjab and upper Sindh for fog and smog in its December 2023 outlook, as Business Recorder reported from the Met Office forecast, and the same plains have carried the closures every winter since. December and January carry the bulk of the reported closures, but the season does not start on a fixed date: in mid-November 2023 the M-5 was closed at the Rahim Yar Khan toll plaza, with traffic diverted between Rukan Pur and Azampur.

Look at the closure lists from the last two winters and a pattern appears. The same stretches recur, and nearly all of them sit on the flat farmland of central and southern Punjab.

Three points come out of that table.

• Lahore to Kot Momin is the recurring M-2 closure. The M-2 runs roughly 375 km between Islamabad and Lahore, and the section from the Lahore end up to the Kot Momin interchange (the exit for Bhalwal) is the one named again and again.
• The M-3 and M-4 go down together. Anyone heading from Lahore to Faisalabad or Multan should assume that if one is closed, the alternative motorway may be too.
• Visibility can fall very low. Dawn reported visibility of 50–60 metres on the closed sections in January 2025. At that distance a car doing the normal motorway limit covers the visible road in under two seconds.

None of these reports names the Salt Range and Potohar stretch of the M-2 between Kallar Kahar and Islamabad. That is a statement about the closure lists, not a promise that the northern half stays clear. And a transfer that starts in Islamabad still has to cross the plains to reach Lahore, which is where the closures sit.

Where to read the motorway fog update, and what each source is for

People searching for a “today motorway fog update” usually want one answer: is my road open right now? Two official bodies are involved, and they answer different questions. PMD forecasts the fog. NHMP decides whether a section is open. Keep that split clear and most of the confusion disappears.

NHMP: the authority on open or closed

In its December 2025 dense-fog travel advisory, NHMP pointed motorists to three channels:

• the 130 helpline, which lets you ask about a specific section;
• FM 95, NHMP’s radio station, which a driver can keep on in the car;
• NHMP’s official social media accounts under @nhmp, for the latest traffic and weather updates.

The 130 line is the one to use at your decision time. Ask about the exact sections on your route, not “the motorway” in general. “Is the M-2 open from Lahore to Kot Momin?” gets a more useful answer than “Is the motorway open?”

PMD: the forecast behind the closures

PMD publishes a fog product for motorways at nwfc.pmd.gov.pk. This is the page behind searches for “pmd fog motorways”, and it is the right place to look a day ahead. It tells you whether fog is expected, not whether a gate is shut. Government weather pages can be slow or unavailable at busy moments, so treat it as one input and have the NHMP channels ready as a fallback.

News reports: pattern, not live status

Dawn, Business Recorder, The Nation and The Express Tribune all publish closure lists during fog spells. They are good for learning which sections tend to close, and that is how the table above was built. They are poor for live status, because a report written at 7 am can be out of date by 9 am when sections reopen.

Airlines, if the transfer meets a flight

Fog hits Punjab’s airports as well as its roads. In December 2025 PIA reported disruption at Lahore, Multan, Sialkot and Faisalabad and asked passengers to check flight status before leaving for the airport. In January 2026 The Nation reported a Lahore–Madinah flight delayed by about three hours and an Abu Dhabi departure cancelled on the same day that five motorways were shut. If the evening transfer ends at an airport, check the flight as well as the road. A road that opens late helps nobody whose flight has already gone.

A checking sequence that works

1. The day before: read the PMD fog outlook and note whether your corridor is in the forecast area.
2. Morning of the event: check NHMP’s social accounts for overnight closures. If sections were shut that morning, assume the same risk that night.
3. At the agreed decision time: call 130 and ask about each section on the route by name.
4. Just before departure: a final check with the driver, who should have FM 95 on for the journey.

Leaving before the fog sets in versus staying overnight

Every late departure after an event comes down to three options. Each has a real cost, and the right choice depends on the event, the route and what the passenger has to do the next day.

Option 1: leave early

Leaving before dark keeps you inside the window NHMP recommends. For a conference, that usually means skipping the closing dinner or the last panel. For a wedding, it may mean leaving after the main function rather than at the end. On a long corridor such as Lahore to Islamabad you want to be clear of the Lahore–Kot Momin stretch before the evening turns, not just leaving the venue before dark. Our motorway tolls and drive times guide for the M-1, M-2 and M-4 gives the typical driving times to work backwards from.

The trade-off is the event itself. A delegate who flew in for a keynote dinner will not thank you for leaving before it starts. Leaving early works best when the evening part is social rather than the reason for the trip.

Option 2: stay overnight and leave mid-morning

This is the default for a late departure in fog season, and it is the one most often dismissed as too expensive. Compare the cost honestly: one extra hotel night against a car and driver held at an interchange for hours, a missed flight, or a passenger arriving at 4 am and useless the next day. NHMP’s advice points to a 10 am start as the earliest sensible departure in dense fog, so a mid-morning pickup with breakfast first is not lost time. It is the plan.

Two practical details make the overnight option work:

• Hold the room early. Hotels close to a large conference or wedding venue can fill up quickly. A provisional booking that can be cancelled costs less than a scramble at 10 pm.
• Move the car booking, don’t cancel it. Converting an evening transfer into a next-morning one keeps the same vehicle type and the same driver briefing.

Option 3: switch to the national highway

When motorway sections close, NHMP has pointed traffic to the Grand Trunk Road as an alternative, as Business Recorder reported in December 2025. It is an option, not an escape from the fog. The Nation’s January 2026 report described fog affecting national highways near Lahore, Manga Mandi, Pattoki, Okara and Sahiwal on the same day the motorways closed. The GT Road also has towns, crossings, slow trucks and unlit stretches. The UK government’s FCDO travel advice for Pakistan warns that driving standards are erratic, especially at night. A foggy night on a national highway combines the worst of both.

Use the national highway for a short hop when the motorway is closed and the passenger has a hard deadline. Do not choose it for a 300 km night run to save a hotel bill.

Convoy and speed restrictions in fog

Fog changes how the motorway works. It is not only a slower version of a normal drive. Understanding what can happen on the road helps you set realistic timings.

Speed

The standard limit for cars and light transport vehicles on motorways is 120 km/h. The Express Tribune reported that limit being restored in June 2026 after a period of reduced limits. In fog, the posted number stops being the guide. NHMP’s advisories tell drivers to slow down, and at 50–60 metres of visibility no sensible driver gets close to the limit. Plan the journey time on the assumption that fog stretches will be driven far below normal speed, and that the time will not be made up later.

Lights, spacing and lanes

The NHMP guidance published during the last two winters is consistent:

• use fog lights, and headlights even in daytime fog;
• do not use high beam, which NHMP says reduces visibility further in fog;
• keep a much larger gap than usual to the vehicle ahead;
• check that wipers work before setting off;
• stay in lane. NHMP has warned that lane violations in fog can be fatal.

For a hired car with a driver, these are also things to check before the trip. Ask whether the vehicle has working fog lamps and whether the driver has recent winter experience on the Punjab motorways.

Convoys and closures

Travellers often ask whether police lead escorted convoys through fog. The NHMP advisories and closure reports cited here do not describe a scheduled convoy system you can plan around, so do not build one into your timings. What they do describe is closure and diversion. When a section closes, traffic leaves at an interchange; on the M-5 in 2023, for example, it was diverted between Rukan Pur and Azampur. For a transfer already on the road, a closure ahead means leaving the motorway and either waiting nearby or taking a national highway. The plan should say in advance which of those you will do.

Building a hold-or-go rule into the booking

The failure mode is predictable. The event overruns, the client wants to leave, the fog is already on the news, and three people start making the decision at once. A hold-or-go rule agreed when the transfer is requested removes that argument. It takes five minutes to write and works for a single executive or a coach of delegates.

What the rule should contain

1. The event end time and the latest departure you will accept. Write both down. “Dinner ends 10:30 pm; latest departure 7 pm in a fog advisory, otherwise 11 pm.”
2. A decision time and a decision owner. Pick a clock time, usually mid-afternoon on the day, and one named person: the travel manager, the event organiser or the passenger. Not the driver, who should never be under pressure to set off.
3. The source that settles it. Agree that the NHMP status on 130 at the decision time, checked against the PMD fog outlook, decides it. Not a forwarded screenshot, and not a news report from that morning.
4. The fallback already booked. A cancellable hotel room near the venue and a provisional next-morning pickup time, typically after 10 am.
5. The mid-route plan. If a section closes while the car is on the motorway, the driver leaves at the next open interchange and calls the decision owner. Agree whether the default is to wait or to continue on the national highway.
6. Onward commitments. List any flight, meeting or hotel check-in at the destination so the decision owner can weigh them. A morning flight from Islamabad changes the calculation more than a late hotel arrival.

A worked example

Example only; times and details are illustrative. A two-day conference in Lahore ends with a dinner that finishes at 10 pm on a January evening. Six delegates need to be in Islamabad for 11 am meetings the next day. When the transfer is requested, the organiser sets the rule: the decision is made at 2 pm by reading the PMD fog outlook and calling 130. If fog is forecast for the Lahore plains that night, or sections closed that morning, the group skips the dinner and leaves at 4 pm. If not, they stay for dinner and leave at 10:30 pm, with cancellable rooms held as a backup. At 2 pm the outlook shows fog and NHMP confirms closures earlier that day, so the group leaves at 4 pm and the rooms are released. The organiser also agreed one more line in advance: if the delegates had stayed and fog was still being reported the next morning, the 11 am meetings would move, not the car.

The example shows what the rule actually does. It does not remove the fog risk. It makes the trade-offs visible early, while there is still time to act on them.

What to put in the transfer request

When you request a car through iDrive, include the event end time, the decision time, the fallback pickup and any onward flight in the notes. For corporate travel with several passengers or recurring events, our business travel car service page explains how multi-leg and multi-passenger requests are handled. For single journeys between cities, start from city-to-city transfers across Pakistan or go straight to the Islamabad to Lahore route page. Requests are reviewed and quoted by our operations team. A vehicle is confirmed only once the quote is accepted and availability is checked, and fog season does not change that. It is one more reason to request early rather than at 9 pm.

If you are organising the ground side of a whole event rather than one transfer, our sister service Pakistan Taxi has a planning guide for conference delegate transport from arrival to departure that covers the other legs of the programme.

Questions people ask

How do I check if the motorway is open today because of fog?

Call the NHMP helpline 130 and ask about the specific sections on your route, or check NHMP’s official @nhmp social media accounts and FM 95. News sites publish closure lists, but they can be out of date within hours as sections reopen.

What time of day is safest to travel on the motorway in fog season?

NHMP’s December 2025 advisory recommended travelling between 10 am and 8 pm, and a Motorway Police spokesperson later described 10 am to 6 pm as generally the safest window during dense fog. Reported closures have usually come late at night and in the early morning.

Which motorway sections close most often in Punjab fog?

Recent closure reports repeatedly name the M-2 from Lahore to Kot Momin, the M-3 towards Darkhana, the M-4 from Pindi Bhattian towards Faisalabad and Multan, the M-5 south of Multan and the M-11 between Lahore and Sialkot.

Should I drive on the GT Road if the motorway is closed?

Only for a short journey with a hard deadline. NHMP has pointed traffic to the GT Road during closures, but national highways around Lahore and southwards have also been affected by fog, and the FCDO warns that driving standards are erratic at night.
