To maintain a 3-second following distance, you can use the following tips:
* Pick a fixed object on the side of the road, such as a tree or a sign.
* When the vehicle in front of you passes the object, start counting to three.
* If you reach three before your vehicle passes the object, you are maintaining a safe following distance.
* If you do not reach three before your vehicle passes the object, you need to increase your following distance.
Maintaining a safe following distance can help you to avoid collisions and keep yourself, the driver in front of you, and other road users safe.
