Pakistan has enforced lower speed limits on motorways and highways from March 26, 2026, aiming to cut fuel use, improve safety, and ease pressure from high global oil prices.
What changed on motorways and highways from March 26, 2026
Pakistan’s National Highways and Motorway Police has started enforcing reduced speed limits on motorways and national highways across the country. The revised limits took effect on March 26, 2026, as part of the government’s broader push to conserve fuel and improve energy efficiency.
Officials say the decision was implemented following directives from Prime Minister Shehbaz Sharif amid rising global oil prices and wider energy concerns. In practical terms, the policy aims to reduce fuel consumption at a national scale by lowering cruising speeds, especially on long-distance travel routes where vehicles spend most of their time at steady speeds.
Because these are “enforced” limits, the key change for motorists is not just advisory messaging. Drivers should expect active checking and penalties where applicable, alongside awareness messaging, especially during the first phase of implementation.
New motorway limits: cars at 100 km/h, heavy vehicles at 90 km/h
The speed limit on motorways has been reduced for different types of vehicles:
- Cars and light transport vehicles: 100 km/h (previously 120 km/h)
• Buses and heavy vehicles: 90 km/h (previously 110 km/h)
The structure reflects a simple idea: heavier vehicles already need longer braking distances and have higher rollover risk at speed, so reducing their limit can improve safety while also lowering fuel burn.
For daily travellers, the biggest change will be felt by car drivers who are used to cruising near 120 km/h on long stretches. A 20 km/h reduction can slightly increase travel time, but the government is positioning it as a trade-off for lower fuel consumption and fewer high-speed crash risks.
For transport operators, the adjustment may require tighter scheduling, especially for intercity routes where arrival times are planned based on higher average speeds. Over time, operators may recalibrate routes and timetables to match the new legal limits.
National highways: 80 km/h for light vehicles, 65 km/h for heavy
On national highways, the limits have also been reduced:
- Cars and light vehicles: 80 km/h (previously 100 km/h)
• Heavy and passenger vehicles: 65 km/h (previously 80 km/h)
Highways often pass through mixed traffic zones and near populated areas, where speed-related incidents can be more severe for pedestrians and local commuters. Lowering limits on these roads can reduce crash severity and improve reaction time in situations involving sudden turns, animals, or slow-moving vehicles.
From a fuel perspective, highways are also important because they carry a large share of commercial movement. Even small efficiency gains per trip can add up across thousands of buses and freight vehicles operating daily.
The practical message for drivers is straightforward: do not assume motorway rules apply everywhere. Highways and motorways now have different caps, and enforcement is expected across both networks.
Why lower speed can reduce fuel use
Energy experts say reducing speed can meaningfully improve fuel efficiency. That may sound counterintuitive to drivers who think “faster means less time, so less fuel,” but fuel burn does not work like that at highway speeds.
As speed rises, aerodynamic drag increases sharply, and engines must work harder to maintain higher cruising speeds. That extra load translates into higher fuel consumption per kilometre. Lowering the cruising speed often reduces this drag and keeps the engine closer to a more efficient operating range.
The International Energy Agency (IEA) has noted that lowering highway speeds by 10 km/h can reduce oil consumption from cars by up to 6 percent. While real-world results depend on road conditions, vehicle type, tyre pressure, and driving style, the direction is consistent: moderate speed reductions can deliver measurable fuel savings across a national fleet.
For Pakistan, where fuel imports impact the current account and price shocks affect inflation, even a few percent reduction in national fuel consumption can be economically meaningful if compliance is wide and sustained.
How enforcement and awareness will shape results
Authorities say a nationwide awareness campaign has been launched to inform motorists and ensure compliance. That campaign matters because policy success depends on behaviour. If drivers ignore the new limits, fuel savings and safety gains will be limited.
In the early weeks, public understanding will be critical. Drivers need clarity on where the motorway starts and ends, how highway limits differ, and how enforcement will be carried out. Transport companies may also need to brief drivers and update internal rules so that schedules do not push drivers toward speeding.
The policy is also tied to global energy pressures. Officials have linked it to geopolitical tensions and oil supply disruptions, noting that countries worldwide introduce austerity measures when fuel markets tighten. Pakistan’s approach is to use speed control as a demand-side tool—one that can be implemented quickly without new infrastructure.
For motorists, the takeaway is practical: follow the updated limits, expect active enforcement, and plan journeys with a small time buffer. For policymakers, the real test will be consistent enforcement and clear public communication so the measure delivers the intended fuel savings, safer roads, and reduced pressure from global oil volatility.
