Bike Rack Light Boards: Why Your Number Plate Must Stay Visible
When your bikes cover your vehicle's number plate and lights, a supplementary light board isn't optional, it's essential. Discover why light boards keep you compliant, keep other drivers safe, and how to choose the right panel for your rack setup and towbar configuration.
If you've ever loaded up a couple of bikes onto a towbar rack and glanced back to see your number plate and brake lights completely blocked, you already understand the problem. It's a common scenario for Kiwi families, weekend riders, and anyone heading to the trails with gear on board. The good news is there's a simple, NZ-made fix.
Why Number Plates and Lights Must Stay Visible
Under New Zealand law, it is illegal to drive with a number plate or vehicle lights obscured. Your lights need to be clearly visible in clear weather from at least 200 metres away, and it's entirely your responsibility to keep them clean, working, and unobstructed.
When you fit a towbar-mounted bike rack or carrier, it will almost certainly block your number plate. That means a supplementary number plate is required by law. Importantly:
- Only official NZTA supplementary plates are permitted, no homemade signs or cardboard numbers.
- Supplementary plates must be fixed to a hard, flat surface, not hung loosely off the back of your rack.
- They must be illuminated when driving at night.
Get it wrong and you're not just risking a fine. You could face 20 to 25 demerit points per offence. More importantly, you're putting yourself, your family, and other motorists at risk if drivers behind you can't see your brake lights or indicators.
