What does the Ford sign mean?

Warns of a ford, a place where the road runs through water. Check the depth and test your brakes afterwards.

Also known as: Ford warning sign

What it means

There is a ford ahead where the road crosses water.

A ford is a shallow crossing where the road runs through a stream or river. The sign has the word Ford in place of a symbol.

Slow down and check the depth before you enter. Afterwards, test your brakes, because they can be less effective after driving through deep water.

Where you'll see it

On country roads that cross streams or small rivers without a bridge.

Rules to know

  • This is a worded warning. 'Ford' may be varied to 'Flood', 'Gate', 'Gates' or 'No smoking'.

  • The depth of water at a ford may be shown in both metric and imperial units, or in imperial units only.

  • After driving through deep water your brakes may be less effective. Test them at the first safe opportunity.
