Road works and temporary
Temporary entrance to a construction or road works site
What it means
Marks the entrance works vehicles use to turn into the site. It's for site traffic only, so carry on past. The hazard is the vehicle ahead of you slowing right down to turn in, so keep your distance and don't try to slip past on either side while it's making the turn.
