Warning triangles

Carrying a hazard alert sign or lamp is vital in case your car breaks down. We test seven options

Travel abroad and the chances are local laws will require you to carry a warning triangle in your car's boot. In fact in some countries such as Spain, you need two - and a fluorescent jacket!

For driving in the UK, carrying a hazard warning sign is not compulsory but is a sensible idea, given the dangers of being stranded on the roadside or motorway hard shoulder, where staying safe depends on yourvehicle being clearly visible to other motorists. Fitting a triangle in a car's boot is usually easy - many models have room for them in the spare wheel well or behind side panels.

There are many versions on offer, available from supermarkets, DIY stores and traditional accessory shops, as well as hazard lamps which can be used instead of a triangle. But which should you go for? We tested seven best-sellers to find out.

Verdict

The brightest performer was the pricey Highway Safety Light, but it failed to win this test because of its poor build quality. The triangles were well matched, with the Speeding GH-074 just pipping the Metro to take our Best Buy award, thanks to good reflective perform- ance and superior design.
