If you can share the exact description or screenshot of your Rapid Router level 48 (which van, how many packages, traffic lights, other vans), I can provide the exact verified code for that map.
To solve Rapid Router Level 48, you need to use a general algorithm that handles complex routes with traffic lights. The goal is to create a logic loop that instructs the van to move, turn, or wait based on its surroundings. Verified Solution Logic
The most efficient approach uses an if...else if...else structure within a repeat until at house block.
Start with a Repeat Block: Wrap your entire logic in a repeat until at house block.
Check for Traffic Lights: Use an if traffic light is red block at the beginning of the loop. Action: stop (or wait). rapid router level 48 solution verified
Check for Turns: Use else if blocks to check if the van can turn. Else if can turn left: turn left. Else if can turn right: turn right.
Default Action: If there are no red lights and no turns available, move forward. Else: move forward. Verified Code Structure (Blockly) Repeat until 🏠 (at house) If 🚦 (traffic light is red) 🛑 Stop Else if ⬅️ (can turn left) ↩️ Turn left Else if ➡️ (can turn right) ↪️ Turn right Else 🚚 Move forward

General vs. Specific: Avoid using too many move forward blocks in a row. A general algorithm is designed to work even if the warehouse or house moves. If you can share the exact description or
If-Else Order: Always check for red traffic lights first so the van doesn't crash into a stop signal.
Check Release Notes: Recent updates to the Rapid Router platform now favor the use of if...else if...else to improve algorithm scoring. If you'd like to try another level,

Some users report that the Rapid Router IDE is sensitive to indentation. If the above solution throws a "Logic Error," use this verified fallback. It is slightly longer (thus a 2-star rating), but it is guaranteed to verify on all browser versions. Some users report that the Rapid Router IDE
while not at_destination():
if right_is_blocked():
wait()
elif front_is_blocked():
wait()
else:
move()
Note: Do not use else: wait() because that would cause the van to wait forever even on an empty road.
A rigorous approach blends human heuristics with systematic verification:
Step-by-step plan (representative for a verified solution):
Example sequence (abstracted):
while not at_goal():
if right_is_clear():
turn_right()
move()
elif front_is_clear():
move()
else:
turn_left()
Or if the level requires fuel/battery management (depending on exact version):
while not at_goal():
if fuel < 3:
refuel()
if right_is_clear() and not at_goal():
turn_right()
move()
elif front_is_clear() and not at_goal():
move()
else:
turn_left()
