Stop! Traffic!

You're a traffic cop, it's rush hour, and the traffic lights aren't working!

You're a traffic cop, it's rush hour - and the lights have failed on the city's busiest intersection! Cars, trucks and bikes move along at high speeds without any care, with only YOU on duty to prevent the carnage. Tap a vehicle to stop it in its tracks, or swipe the vehicle to speed it on its way (but don't speed up too many vehicles, or smog will build up and you'll be penalized). Game over if two vehicles crash. Try and last as long as you can, and be rewarded by a points system that moves almost as fast as those cars! Good luck, officer!
