Which should be cross-checked when navigating with city streets featuring closures?

• A. The GPS color
• B. Landmarks and cross-streets, with dispatch confirmation
• C. Personal schedule
• D. Traffic light timing only

Answer: (B)

When navigating through city streets with closures, you should cross-check landmarks and cross-streets and obtain dispatch confirmation. This approach combines real-world cues with official guidance, which is crucial when routes are changing due to closures. GPS can lag or misrepresent closures, so landmarks—like a distinctive building, bridge, or park—help you verify you’re on the correct block and approaching the right intersections. Checking cross-streets ensures you’re on the intended leg of the route, preventing detours that could waste time in a high-stakes EMS situation. Dispatch confirmation provides authoritative routing instructions and any last-minute updates about closures or road blocks, keeping your team aligned with current conditions and the incident plan.

Relying on GPS color alone isn’t meaningful for routing accuracy, and personal schedules don’t address the actual road conditions or detours. Focusing only on traffic light timing ignores closures and detours that can drastically alter your path and arrival time.
