A cattle grid (or stock grid)(British English) or cattle guard (American English) – also known as a vehicle pass, Texas gate, stock gap (in U.S. Southeast ) or, in New Zealand, a cattle stop – is a type of obstacle used to prevent livestock, such as sheep, cattle, pigs, horses, or mules from passing along a road or railway which penetrates the fencing surrounding an enclosed piece of land. It consists of a depression in the road covered by a transverse grid of bars or tubes, normally made of metal and firmly fixed to the ground on either side of the depression, such that the gaps between them are wide enough for animals' legs to fall through, but sufficiently narrow not to impede a wheeled vehicle or human foot. This provides an effective barrier to animals without impeding wheeled vehicles, as the animals are reluctant to walk on the grates.

Famous quotes containing the word cattle:
“To-night the winds begin to rise
And roar from yonder dropping day:
The last red leaf is whirld away,
The rooks are blown about the skies;
The forest crackd, the waters curld,
The cattle huddled on the lea;”
—Alfred Tennyson (18091892)
