The Basics

Place colored cars at the end of any row or column, they will drive towards the center and any resulting 3 cars of the same color in column or row will be removed. After that any cars that are no longer blocked will drive until they are removed from the field or blocked. Some typical goals are to free ambulances (get them off the field) or uncover helicopter landing pads (make sure no car is on top of it).

Difficulty

The levels that I have played are all quite easy and if they keep using the same setup for the higher levels, I doubt it will become a real challenge.

Variation

There is some variation in the goals, which requires a slightly different way of approaching the puzzle.

Visually

Solid graphical user interface.

Free vs Paid

Fully functional for non spenders. You can purchase packs with in game credits and boosters that help you reach your goals.

Is It Any Good?

I give Traffic Puzzle 7 out of 10 stars. Nice variation on Match 3, but too simple.
