What you need to understand
Following distance needs to grow when visibility, road grip, traffic, or your vehicle’s stopping ability becomes worse.
Start with the official driver handbook for the state where you will apply. It is the best source for current rules, exceptions, and exam requirements.
How to apply this on the road
Pick a fixed roadside marker and count the time between the vehicle ahead passing it and your vehicle reaching it.
Think about how other road users could act unexpectedly. Good decisions leave enough time and space to respond safely.
Two-minute study challenge
Describe three situations in which you would increase your following distance.
Check your answer against your state's current handbook. If you are unsure, revisit that topic before your next practice session.
What to do next
- Read the relevant handbook section.
- Explain the main rule in your own words.
- Take a free practice session and review any missed answers.
- Return to this guide after studying another topic.
