Bus Traffic Fever! Level 38 Guide: How to Clear Gridlock

To beat Level 38 in Bus Traffic Fever!, you must match your vehicle dispatch order to the passenger line's immediate colors while keeping at least one staging dock completely empty. Moving unblocked buses without matching passengers fills your docks prematurely, creating an unrecoverable stall.

Core Rules for Managing Staging Bays

Level 38 restricts your room for error by limiting staging slots. Sending a bus forward when its passengers are buried behind other colors leaves that bus sitting idle in a loading bay until the front of the queue clears.

Reserve a flex bay: Always keep at least one dock slot empty. Only route a bus into your final available bay if it matches the front-of-line passengers, fills completely, and exits right away.
Match the front turnstile first: Never send an unblocked bus to the docks simply because it has an open driving path. If the front passengers are blue and yellow, an unblocked red bus will block the dock until all preceding blue and yellow passengers board.
Avoid rapid tapping: Tapping multiple buses in rapid succession creates traffic bottlenecks in the center aisle. If a vehicle pauses mid-turn because another bus is moving ahead of it, its tail can trap adjacent units.

Passenger Queue Status	Parking Lot Condition	Required Action
Matches front of queue	Driving path completely clear	Dispatch directly to the active dock for immediate boarding.
Matches 2–3 spots back	Bus blocks a critical exit route	Hold until the preceding queue colors clear, then dispatch.
No active match in queue	Bus obstructs key internal aisles	Park in a staging bay only if two or more bays remain empty.

Level 38 Unblocking Sequence

Clearing the congestion requires a three-phase approach that systematically frees interior lanes without flooding the loading docks.

Phase 1: Clear Unobstructed Perimeter Buses

Examine the outer boundary for perimeter vehicles that have zero obstacles in their forward paths. Verify whether any of these outer buses match the first two passenger groups in line. Dispatching a matching perimeter bus frees its starting space immediately, turning that vacated stall into an essential turn lane for inner vehicles.

Phase 2: Dislodge Central Bottlenecks

With outer clearance created, identify inward-facing vehicles that block the central corridor. Trace each vehicle's forward path to the exit before tapping it. Ensure its departure trajectory completely clears adjacent bumpers so trailing vehicles do not get clipped mid-turn.

Phase 3: Empty the Back Rows

Once the central aisle is open, the back parallel rows have straight, unobstructed exit lanes. Match each remaining vehicle directly against the queue order. Pull them out one by one until the lot is empty.

Gridlock Recovery

If multiple bays become tied up with partially filled buses, halt all dispatches:

Look only at the passenger standing at the very front of the line.
Scan the grid solely for a bus matching that specific color, ignoring every other open lane.
Move only the minimal number of blocking buses required to path that target vehicle into the remaining dock slot.
