Yes — TSA PreCheck runs at Washington (IAD). PreCheck lanes are open during regular screening hours, though an individual lane can close at off-peak times. PreCheck costs $76.75–$85 for 5 years and lets you keep your shoes, belt, and laptop on.
IAD runs PreCheck lanes through the day, but a single lane can close off-peak. The live IAD TSA wait times board shows a dash when a PreCheck lane is closed, so you can pick a checkpoint that has one open.

Live where IAD reports a feed, and our typical-pattern estimate when a lane is quiet. A dash means that lane is closed right now.
IAD has 4 terminals (A, B, C, D), and PreCheck lanes operate at checkpoints across them. Hours vary by checkpoint, so a lane may close at off-peak times — the live board flags which are open, and which checkpoint sits closest to your gates.

A faster lane means a shorter security buffer — but only when the lane is actually short. Instead of guessing, set your Leave-By Time: it folds the live IAD PreCheck wait, your drive with traffic, and the walk to your gate into one exact time to leave home. When PreCheck is moving, you see the difference — with room to breathe.

IAD runs TSA PreCheck lanes during regular screening hours, though an individual lane can close at off-peak times — check the live board before you go.
PreCheck lanes operate at IAD checkpoints across 4 terminals (A, B, C, D), and the live board shows each PreCheck wait next to the standard one.
PreCheck usually clears you faster, but plan your arrival from the live IAD wait and your Leave-By Time rather than a fixed rule, since lanes still slow at peak hours.
Global Entry costs $120 for five years and includes TSA PreCheck, so it is the better value if you ever fly internationally; PreCheck alone fits domestic-only travel.
