What is a hazard warning line road marking?

Hazard warning lines are broken white lines in the middle of the road, separating the left and right lanes.

The difference is that the line is longer than the typical white lines indicating lanes and the gaps between them are shorter.

You should always look out for hazard warning lines when approaching a junction or central refuge.

What does it mean when a hazard warning line road marking appears?

Hazard warning lines mean there is a hazard ahead and you should not cross or straddle it.

These road markings only appear when a hazard is not immediately obvious.

Hazard warning lines can come in many different forms and can be used in various ways.

For example, a hazard warning line can indicate an approach of a sharp bend.

Can I cross a hazard warning line road marking?

You should never cross a hazard warning line unless you are certain it is safe to cross.

If you see a hazard warning line, you should take all precautions possible to avoid the hazard.

This may include slowing your speed and potentially manoeuvring around the hazard.

But there are also double white lines where the nearest line to you is broken, meaning you can cross the lines to overtake provided it is safe and you can complete the manoeuvre before reaching a solid white line on your side.

White arrows can also be used to indicate that you need to get back onto your side of the road.

If there is a double white line and the one nearest to you is solid, then you mustn't cross or straddle it unless it is safe to do so and you need to join an adjoining premises on the other side of the road.

You can cross the line if necessary, providing the road is clear, to pass a stationary vehicle, overtake a cyclist, horse or road maintenance vehicle.
