244. Warning triangle

A warning triangle is a portable reflective safety device used to warn approaching traffic about a stopped, broken-down or crashed vehicle or another obstruction on the road. It should be placed far enough from the hazard to give other drivers time to react and should remain clearly visible. The required distance and situations in which a warning triangle must be used vary between countries, so drivers should know the local rules and keep the triangle easily accessible in the vehicle.

What is a warning triangle?

A warning triangle is a portable reflective device placed on the road to warn approaching traffic about a stopped vehicle, accident or other hazard.

When should a warning triangle be used?

It is generally used when a vehicle is broken down, involved in an accident or creating an obstruction. The exact legal requirements vary between countries.

How far from the vehicle should a warning triangle be placed?

The required distance depends on the country and type of road. Higher-speed roads usually require the triangle to be placed farther away so approaching drivers have more time to react.

Where should the warning triangle be placed?

Place it where it is clearly visible to approaching traffic and where doing so does not put you in unnecessary danger.

Should you use hazard warning lights as well as a warning triangle?

Often, yes. Hazard warning lights and a warning triangle can work together to make a stopped vehicle more visible. The legal requirements vary by country.

Should the warning triangle be easy to reach?

Yes. It is useful to keep it accessible without having to unload large amounts of luggage, especially because it may be needed quickly in a dangerous roadside situation.
