Can I Run a Lighter Over My Seatbelt for Roadworthy?

It's a common question — and a tempting shortcut. If your seatbelt webbing is fraying, can you just run a lighter over the loose fibres to melt them back together and pass a roadworthy inspection?

The short answer: No. And here's why.

Why the Lighter Trick Doesn't Work

Seatbelt webbing is made from woven polyester fibres engineered to absorb and distribute the forces of a collision. When you apply heat from a lighter to frayed webbing, you're not repairing it — you're damaging it further.

• Heat weakens the fibres — Melting the edges of frayed webbing fuses the surface fibres but damages the structural integrity of the weave underneath. The belt may look tidier but it's actually weaker.
• It won't pass a roadworthy inspection — Roadworthy inspectors are trained to identify damaged webbing. Burn marks, discolouration and melted edges are a clear sign of damage and will result in a fail.
• It's a safety risk — A seatbelt that has been heat-damaged may fail in a collision, even if it looks intact.
• It may void insurance — Modifying or attempting to repair a seatbelt with non-approved methods could void your insurance coverage in the event of an accident.

What Roadworthy Inspectors Actually Look For

Victorian roadworthy inspectors check seatbelt webbing for fraying, cuts, tears, burns, chemical damage and significant wear. Any of these — including evidence of heat damage — will result in a fail. There is no DIY fix that will pass inspection.
