Final answer:
To determine if you're following another rider too closely, use the two-second rule. Keep a distance of at least two seconds from the vehicle in front of you.
Step-by-step explanation:
To determine whether you are following another rider too closely, you can use the concept of the two-second rule. This rule states that you should keep a distance of at least two seconds from the vehicle in front of you.
To calculate this distance, pick a fixed object on the road and start counting when the vehicle in front of you passes that object. If you reach the same object before counting to two, you're following too closely.
