Deer grates are heavy concrete or steel structures used in conjunction with or in place of a driveway gate to keep deer out.
Properly engineered deer grates don't allow deer to pass over because:
1) the top has rounded designed slats or ribs they can't walk on
2) the spacing between the grates won't allow deer to bypass the ribs
