Did You Know: If The Green Light Is On, You Can Use The Emergency Lane. Here's Why
Yes, it's legal to use certain emergency lanes in Malaysia, but only under specific conditions.

If you've ever been stuck in a highway crawl while cars zoom past on the emergency lane, you've probably thought, "Wah, so berani (brave)"
But here's the thing — those drivers might not be breaking the law. They could be using what's known as the Smart Lane.
This special lane is only open to regular traffic when a flashing green light appears above the emergency lane.
Let's break down what the Smart Lane is, why it exists, and where you'll find it.
The Smart Lane lets you use the emergency lane — but only when the green lights and signs say so
The Smart Lane is a PLUS Malaysia initiative that temporarily opens the emergency lane during peak traffic periods — like long weekends, festive seasons, and balik kampung surges.
It helps ease congestion at known chokepoints by giving drivers an extra lane to move through.
However, it's only active at specific times. Here's how you know it's in effect:
- You'll see a yellow signboard that reads "PENGAKTIFAN SMART LANE"
- A flashing green arrow light will appear above the leftmost (emergency) lane
- You can also check real-time updates via the PLUS app or @plustrafik on X
If you don't see these indicators, do not use the emergency lane — it's still illegal unless the Smart Lane is officially active.
When using the Smart Lane, there are rules to follow
Just because it's open doesn't mean it's a free-for-all. Once activated, there are a few key guidelines:
- Keep left and only enter the Smart Lane when the signage indicated it's open
- Drive cautiously — the lane is narrower than usual, and breakdowns may still occur
- Keep your speed safe (PLUS typically recommends driving between 60km/h and 80km/h)
- Signal early and rejoin the main lane safely at the end of the Smart Lane stretch
And remember — once the green light switches off, it's no longer legal to use the lane. Don't get caught out.
But what if there's a real emergency while the Smart Lane is active?
It's a valid concern — the emergency lane exists for breakdowns and ambulances.
But PLUS has contingency plans in place:
Patrol teams are deployed in Smart Lane zones to monitor traffic and assist vehicles in distress
Emergency lay-bys and designated breakdown bays remain available for use
If a vehicle breaks down in the Smart Lane, PLUS Ronda or highway personnel will be alerted and provide on-site assistance as quickly as possible
For serious emergencies, traffic may be halted or redirected to allow ambulances or tow trucks through
Drivers are reminded to stay alert and keep a safe following distance in Smart Lane stretches, as sudden stops may still occur.
So yes, the lane is open to traffic — but its emergency function is still active, just managed with on-ground support.
As of 2025, there are 28 Smart Lane locations across the PLUS highway network, spanning the northern, central, and southern regions of Peninsular Malaysia
Here's a list of where they are located:
These Smart Lanes are activated during major holidays or when congestion hits critical levels. Always check official PLUS updates before your trip.
