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 is important for avoiding accidents and keeping yourself and others safe. By following these tips, you can ensure that you have plenty of time to react to unexpected situations on the road.
