Each stage introduces new lanes, turning rules, and crosswalk quirks. Tap the lights in sequence to give every direction a clear window.

• Watch for queued emergency vehicles—they demand instant priority or the level fails.
• Let one route clear fully before flipping signals; near-misses count against your grade.
• Track countdown timers so reckless drivers do not jump the lights while you are switching.

The puzzles scale from sleepy suburbs to downtown tangles, rewarding multitasking instead of brute force.

FlashGamesBox keeps this traffic-control classic alive whenever you crave a quick dose of signal juggling.
