DIRT - Driver’s Informative Reaction Timer

It is vital to be able to react quickly when something unexpected happens on the road, as a low reaction time can help you prevent accidents, or at least minimize their effects.
DIRT - Driver’s Informative Reaction Timer is an interesting application that enables you to test your abilities using just your computer. It measures your perception and reaction time, and it is suitable even for novice users.

Test your perception and reaction time in a safe environment

The application presents you with a fairly simple scenario that frequently occurs when on the road, and it measures how quickly you can perceive and react to an event.
Once you have started the test, you need to press the Shift key – which acts as your accelerator pedal – and keep an eye on the green light, which will change to red after a random delay. When you see the red light, you have to release the Shift Key and, using the same finger, tap the Spacebar – your brake pedal in this scenario.
You can also set the speed the vehicle is traveling at in order to determine how much distance will be covered until you can react to an event and bring the car to a stop.

Complete with your friends and check your reaction time in various situations

DIRT - Driver’s Informative Reaction Timer takes the last three valid results and calculates an average perception, reaction and total time. These values can be saved to the log and printed.
If you wish to complete with others, you can set a different tag for each user in order to ensure the results will not be mixed up.
The optional sound effects can be disabled if you find them to be unnecessary, and those who are more familiar with the Metric system can switch to it at any time.

Well-designed app that comes with extensive documentation

The application features a fairly straightforward UI design, and the instructions that are offered at first launch are very helpful for first-time users.
A more detailed manual can also be accessed at any time if you run into any issues, as it provides helpful explanations for every available function.
Overall, DIRT - Driver’s Informative Reaction Timer is a great testing tool for drivers, but you can also use it if you just want to have a bit of fun competing with your friends. It measures your perception and reaction time when presented with an unexpected event, and it is very novice-friendly.
