This speedometer is designed by putting it on images and videos that involve driving. In this example, the speedometer is used for a car, separating the speed into increments of 25-40 mph with a max speed of 100-160 mph. I also set up the speedometer in km/h and included yellow and red sections to alert you to the dangers of going at a very high speed. It also applies to trains but has three different categories with different max speeds. There were three options of a train speedometer, with a max speed of 80, 100, and 220 mph. The speedometer diagram was used to simulate recorded videos and estimate photos.
The speedometer has three signal words: warning, danger, and peril. It applies to cars and trains.
All caps were used for road conditions, while the exclamation mark was added for emergencies and sudden traffic slowdowns.
| Signal word | All caps | Exclamation | Notes |
|---|---|---|---|
| Warning | Yes | No | If the speedometer is 16.7% above the speed limit or at least 80 mph, or if there are weather advisories in the area |
| Danger | Yes | Yes | If the speedometer is 33.3% above the speed limit or at least 99 mph or if there is a weather watch or traffic involving construction |
| Danger | No | Yes | Only used in any weather warning, including high - very high fire danger or red flag warning, or if obstructions or accidents cause traffic and bad road conditions |
| Peril | Yes | Yes | If the speedometer is 50% above the speed limit or at least 110 mph or if there is a road closure related to an accident or weather |
