Road rules: how to safely pass a vehicle that's towing

Getting stuck behind a slow vehicle with a trailer can be frustrating. We share top tips for passing safely. 

Patience is essential when you find yourself behind a vehicle that’s towing. Wait for a long, clear stretch or – even better – a passing lane.

Consider visibility, road conditions, the trailer’s size and stability; approach with a courteous mindset, giving both yourself and the towing driver time to manoeuvre safely.

How slow is the towing vehicle travelling? Note the layout of the road. Is it straight or winding? Are there double yellow lines ahead?

Can you safely complete the pass and still have at least 100 metres of clear road ahead once you’re back in your lane?

Signal early and clearly, check your mirrors frequently, and be efficient with your manoeuvres.

If you’re the one towing, start with a quick check of your trailer. Make sure your WoF and registration are up to date, do a visual inspection of the trailer and confirm that the load is compliant with your vehicle’s towing capacity. Check the tyres, lights (including headlights, brake lights and indicators), safety chains and any tie-downs.

Ensure the trailer is hitched properly. The tow ball must be correctly seated in the coupling, the latch fully secured, and safety chains attached. If you’re unsure, seek guidance from someone experienced.

Once you’re on the road, remember that towing changes how your vehicle behaves. You’ll need more space to brake, turn and accelerate, so take it easy and avoid sudden movements. 

Top tips for towing

  • Avoid overtaking if it's not necessary; towing reduces acceleration and stability, so it’s safer to stay back unless you have a long, clear stretch of road ahead.
  • Increase your following distance to at least four seconds when towing. This gives you extra time to brake safely.
  • Follow the speed limit and drive to the conditions. Always drive at a safe speed for the road and traffic conditions and remember that safe speed can never exceed the legal speed limit. Trailers must not exceed 90 km/h, even if the road limit is higher.
  • Use your mirrors often so you’re aware of following traffic and trailer stability. This helps to be aware of your safety cushion.
  • Keep left and let others pass if traffic starts to build up behind you; it’s courteous and helps keep everyone safe.
  • Plan ahead for wider turns, longer stopping distances, and take extra care when entering or leaving ramps and car parks.
  • Use a spotter at the ramp. Having someone guide you while reversing or launching will make the process safer and less stressful.

Towing safely isn’t just about getting from A to B – it’s about sharing the road, showing courtesy and keeping things calm both on the highway and at the boat ramp. A quick check, a steady drive and a bit of patience will ensure your towing trip starts and ends safely.
