Returns current vehicle wait times at WA→Canada land border crossings: I-5 (Peace Arch, Blaine), SR 543 (Pacific Highway, Blaine), SR 539 (Lynden), and SR 9 (Sumas). Each crossing reports a general-purpose lane and a Nexus lane; SR 539 adds a truck lane and SR 543 adds truck and FAST truck lanes — eleven entries in crossings[], one per lane. crossingName is a route code (e.g. "I5", "I5Nexus", "SR543Trucks"); the readable name is in location.description. Wait times are in minutes. A crossing reporting no current data is still returned — only waitTimeInMinutes is omitted. Use for "how long is the border wait?" questions.

Returns active WSF ferry service disruptions, delays, and bulletins. Each alert carries a one-line summary plus the bulletin title, kind, and full body — the body is where detail such as a replacement sailing appears. Each alert includes impacted route IDs — cross-reference with wsdot_get_ferry_routes to resolve route IDs to human-readable route names. Some IDs (seasonal, San Juan interisland, or international Sidney B.C. routes) may not appear in wsdot_get_ferry_routes for a given date.

Returns the main WSF ferry routes operating on a given date, each with the directed terminal pairs it serves that day (terminalPairs) — departing and arriving terminal IDs and names, which are exactly the pairs wsdot_get_ferry_schedule accepts for that date. Route IDs correspond to impactedRouteIds in ferry alerts from wsdot_get_ferry_alerts, though some alert route IDs (seasonal, San Juan interisland, or Sidney B.C.) may not appear in this list. For the full terminal list with coordinates, use wsdot_get_ferry_terminals.

Returns departure times for a specific WSF ferry route on a given date. Requires numeric terminal IDs — use wsdot_get_ferry_terminals to resolve terminal names to IDs; terminalPairs on wsdot_get_ferry_routes lists the pairs with service on a date. Set remainingOnly to true to show only future departures for today (useful for "next ferry" queries). For future dates, all sailings for that day are returned. Each sailing carries its vessel ID, WSF's loading-rule code, and the pair's annotations that apply to it — notes such as "No interisland vehicles" that decide whether a sailing takes a car. Sailing times are ISO 8601 UTC while tripDate is the Pacific service day, so evening sailings carry the next UTC date — convert to America/Los_Angeles before quoting a clock time. Cancellations are not carried here — WSF drops a cancelled sailing from the schedule instead of flagging it, so a listed sailing is not confirmation that it will run. Check wsdot_get_ferry_alerts for disruptions; those are scoped to a route, not an individual sailing.

Returns all WSF ferry terminals with their numeric IDs, names, abbreviations, and coordinates. Call this first to resolve human-readable terminal names (e.g. "Bainbridge Island", "Seattle", "Kingston") to the numeric terminal IDs required by the schedule and space tools. The terminal list is small (20 terminals) and rarely changes.

Returns current road conditions for all Washington State mountain passes: status, weather, road condition, traction laws, temperature, and elevation. Includes all 16 passes (Snoqualmie, Stevens, White, Blewett, Cayuse, etc.). Use for "is the pass open?", traction law status, or winter driving planning.

Returns real-time drive-up and reservable vehicle space available at WSF terminals for upcoming sailings. Use for "will I make the ferry?" or "how full is the next sailing?" questions. Optionally filter to a specific terminal by ID (use wsdot_get_ferry_terminals for the ID). driveUpSpaceCount is the key field — zero means the drive-up lane is full. Destinations are arrivingTerminalIds, not the itineraryLabel string: a sailing can serve several terminals, and those IDs are what wsdot_get_ferry_schedule accepts. Results are paged by terminal (default 5, max 20): offset/limit select whole terminals and totalCount counts matching terminals, not sailings — every sailing of a returned terminal is included, so page size varies with how many departures each terminal carries.

Returns current dynamic toll rates for WA express lanes and tolled facilities: SR 99 (WSDOT Tunnel), SR 167 HOT Lanes, I-405 Express Lanes, SR 509 tolled segment, and the SR 520 Bridge. Rates are time-banded and change dynamically based on traffic conditions. Filter to one facility with stateRoute ("SR 520", "520", "I-405", or "405" all work). Each row reports stateRoute as the bare, zero-padded number the feed carries ("099", "405") — the posted designation is in the rendered text. Results are paged — pass offset/limit to page through the matching set. A page ends at limit or at a 24,000-byte response budget, whichever comes first; the notice reports the next offset.

Returns current vs. average travel times for named WA highway corridors (I-5, I-90, SR 520, SR 99, I-405, SR 167, etc.). Use for "how congested is I-5?" or commute time estimates. The route filter matches two ways: a route designation ("I-5", "5", "SR 520") returns every corridor measured on that route, and any text also matches corridor names ("Everett"). When current time exceeds average, the corridor is congested. Results are paged — pass offset/limit to page through the full set. A page ends at limit or at a 24,000-byte response budget, whichever comes first; the notice reports the next offset.

Returns real-time AIS positions, speed, heading, ETA, and dock status for all active WSF vessels. Use for "where is the ferry now?", vessel tracking, or checking if a vessel is in service. Position data may lag by 30–60 seconds. Many fields are null for vessels not currently operating.

Returns active WA highway alerts: incidents, construction, closures, and restrictions. Filter by state route ("I-90", "90", "SR 520", or "520" all work), WSDOT region (Northwest, Olympic, Southwest, South Central, North Central, Eastern), or milepost range, matched against the alert's full extent. Omit all filters to return all current statewide alerts. Results are ordered by alertId and paged — pass offset/limit to page through the full set. A page ends at limit or at a 24,000-byte response budget, whichever comes first; the notice reports the next offset.

Returns WSDOT highway camera locations, descriptions, and image URLs. Camera images are copyright WSDOT — only metadata and image URLs are returned, not image bytes. Filter by state route ("I-90", "90", "SR 520", or "520" all work), WSDOT region, milepost range, or words in the camera title ("Snoqualmie"). Results are ordered by cameraId and paged — pass offset/limit to page through the full set. A page ends at limit or at a 24,000-byte response budget, whichever comes first; the notice reports the next offset.
