What you need to understand
Rain can reduce tire grip, while fog limits how far ahead you can see. Braking and steering inputs should be smoother.
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
Slow to a speed that matches what you can see and the available traction; leave extra space.
Think about how other road users could act unexpectedly. Good decisions leave enough time and space to respond safely.
Two-minute study challenge
List what you would change about speed, space, and visibility in heavy rain.
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.
