How to Play Traffic Stop: Rules, Scoring and Tips
Traffic Stop looks like a simple tapping game, but players who rush it lose their three strikes in the first twenty seconds. The trick is that it is really a reading game: every decision is a quick comparison between two numbers. This guide explains exactly how the game judges each car, how the score works, and the habits that turn a nervous first shift into a calm three-star run.
The one rule that matters
Every car on the road carries a white radar tag with its speed in km/h. The round sign in the top-left corner shows the speed limit. If the number on the tag is higher than the number on the sign, the car is speeding and you should pull it over. If it is equal or lower, leave it alone.
- Over the limit: tap it. A limit of 60 means a car showing 61 or more gets a ticket.
- Exactly on the limit: legal. A 60 in a 60 zone drives on. Around a third of the legal traffic sits right on the limit, precisely to catch players who tap "big-looking" numbers.
- Under the limit: legal, however slow it looks.
How strikes work
You have three strikes per shift. There are exactly two ways to lose one:
- A wrong stop. You tapped a legal car. It flashes red, a "legal!" message appears, and the car keeps driving.
- A missed speeder. A car that is over the limit drives off the bottom of the screen without being stopped.
Both cost the same, which is important. Many new players tap everything that moves fast "just in case". That trades a possible miss for a very likely wrong stop, and it usually ends the shift sooner. When you are unsure, spend half a second reading the tag.
Scoring and stars
Each correct stop earns 100 points. On top of that you get:
- An early-catch bonus of up to 50 points, which is bigger the higher up the road the car is when you stop it. A speeder stopped right at the top earns close to the full bonus; one stopped just before it leaves earns almost none.
- A streak bonus of 10 points for every correct stop in a row after the first, capped at +100. A wrong stop or a missed speeder resets the streak to zero.
Stars depend only on strikes, not on points. Finish the 40-second shift with no strikes for three stars, one strike for two stars, and two strikes for one star. Any finished shift unlocks the next one. So if you are chasing stars, play carefully; if you are chasing a high score, also try to stop speeders early and keep your streak alive.
A shift-by-shift overview
There are ten shifts, and each one adds a single new idea:
- Shifts 1–2 have two lanes. Speeders on the first shift are 18 to 45 km/h over the limit, so they are easy to spot. Shift 2 uses a school-zone limit of 40, where perfectly ordinary numbers like 55 are already illegal.
- Shifts 3–4 add a third lane. On Market Street speeders are only 8 to 25 km/h over a limit of 50, so you can no longer rely on "big number = speeder".
- Shift 5, Roadworks Ahead, introduces a limit change: 70 for the first 20 seconds, then 50.
- Shifts 6–7 open up four lanes and faster traffic. On the Expressway the limit is 100 and some speeders are just 5 over.
- Shifts 8–10 combine dense four-lane traffic with one or two limit changes. The final Chief's Challenge goes 60, then 80, then 50, with speeders as little as 3 km/h over.
Handling a limit change
When the sign changes, it pulses and a NEW LIMIT message appears in the middle of the road. From that instant every car is judged against the new number, including cars that were already on the road. That has two consequences:
- When the limit drops (for example 70 to 50), cars doing 55 or 65 that were legal a moment ago are now speeders. Scan the whole road immediately — especially the lower half, because those cars are about to escape.
- When the limit rises (for example 50 to 70), the opposite happens. A car you were about to tap at 60 is suddenly legal. Take your finger off the screen and re-read.
Habits of three-star players
- Say the limit out loud (or in your head) at the start of each shift and after each change. It turns every decision into a quick "above or not" check.
- Work from the bottom up. Cars near the bottom are the ones about to cost you a strike. Clear those first, then look further up the road for early-catch bonuses.
- Use the speed of movement as a hint. A car's radar speed also sets how fast it moves on screen, so the cars racing down the road are the ones to read first. Just remember that on a low-limit shift, even a slow-moving car can be over.
- Watch trucks carefully. Trucks never travel far above the limit, but they can still be just over it.
- Pause if you need to. The Pause button (or P) freezes the road. The game also pauses automatically if you switch to another tab.
Playing with a keyboard
On a computer you can play without the mouse. Press 1, 2, 3 or 4 to pull over the car that is furthest down in that lane; the lane numbers are printed faintly at the bottom of the road. This is often faster than clicking on the four-lane shifts, but it only ever targets the leading car in a lane, so a speeder hiding behind a slow car still needs a click.
Where to go next
Once you have three stars on every shift, try replaying the early shifts for a higher score by catching speeders near the top of the road and never breaking your streak.
