加州出發前查路況：在 QuickMap 分開看封路、事故與雪鏈資訊
Caltrans QuickMap 把交通速度、車道與道路封閉、CHP 事故、道路訊息牌、攝影機畫面及雪鏈管制等資料放在地圖上。出發前可先選定路段，再開啟與行程有關的圖層；例如前往山區時，不宜只看交通顏色而忽略封路與雪鏈資訊。這是即時查詢工具，本文不是任何路線的暢通保證。
官方常見問題指出，各資料層的更新間隔不同，不能把一張截圖當作之後整段行程的狀況。可在安全停車或由乘客操作時重新查看，並留意個別事件的時間和範圍。本文直接連結官方工具，不嵌入可能已過時的地圖；現場標誌及執法人員指示仍須遵守。

Before a California drive: separate closures, incidents and chain controls in QuickMap
Caltrans QuickMap brings together traffic speeds, lane and road closures, CHP incidents, message signs, camera snapshots and chain controls. Before leaving, locate the part of California you will use and enable the layers that matter to the trip. For a mountain journey, traffic colors alone are not enough: look separately for closures and chain-control information. This guide does not declare any route open or safe.
Caltrans explains that the underlying layers update at different intervals. A screenshot therefore cannot represent conditions for an entire later journey. Recheck while safely parked or have a passenger handle the device, paying attention to the affected location and event information. Use the linked official service rather than treating an embedded or saved map as current, and follow roadside instructions.
