Merging onto a motorway should be a smooth and safe process, but many drivers are turning it into a dangerous and frustrating experience. Experts warn that common mistakes on motorway on-ramps are not only causing congestion but also increasing the risk of accidents. So, what’s going wrong, and how can you avoid being part of the problem? Here’s the part most people miss: it’s not about slowing down or stopping—it’s about using the on-ramp to your advantage.
The AA highlights a widespread issue: drivers often slow down or even come to a complete stop while merging, which disrupts the flow of traffic and creates hazards. As holiday traffic ramps up, AA road safety spokesperson Dylan Thomsen emphasizes the importance of using the full length of the on-ramp to match the speed of motorway traffic and find a safe gap to merge. But here’s where it gets controversial: while some drivers believe slowing down is cautious, Thomsen argues it’s actually reckless. “Don’t slow down or stop on an on-ramp as you indicate right,” he advises. “You become a hazard to cars behind you and can cause traffic build-up.”
Thomsen reminds drivers that vehicles already on the motorway have the right of way. “You must find a safe gap—do not force your way in,” he says. He recommends signaling right for at least three seconds, checking blind spots, and keeping an eye on vehicles in far lanes that might change into your path. If a gap doesn’t appear immediately, adjust your speed slightly—without stopping—to merge smoothly when an opening becomes available.
And this is the part most people miss: some on-ramps have variations, like ramp signals or double lanes, which require extra attention. For example, Auckland’s motorways feature ramp signals that must be treated as red lights, not suggestions. Double-laned on-ramps that merge into one lane before entering the motorway require a zipper merge—always indicate, check mirrors, and watch for blind spots.
NZTA echoes this advice, urging drivers to treat on-ramps like merge lanes. “Using the entire merge lane gives you time to match the speed of traffic and find a safe gap to merge like a zip,” they explain on Facebook. Merge lanes are designed to taper naturally, guiding you into the flow of traffic. The key is to merge at the end of the lane, ensuring you’re at motorway speed and providing a predictable entry point for other drivers.
But here’s where it gets controversial: failing to follow these rules can result in penalties. Ignoring ramp signals is treated like running a red light, with a $150 fine. Entering the motorway unsafely or endangering others also carries a $150 fine. In extreme cases, reckless driving charges could land you in court. So, is slowing down on an on-ramp a cautious move or a dangerous mistake? Let’s discuss in the comments—what’s your take on the safest way to merge?
