5 sample questions with answers
Signs & Signals
1. You are taking a practice test for your driver's permit. The answer key shows that question 10 is False, question 13 is False, and question 42 is False. What does this pattern tell you about studying?
- You should review the topics for those questions to understand what you got wrong
- False answers don't matter as long as you pass with 80% correct
- You should memorize that those specific question numbers are always False
Correct answer: You should review the topics for those questions to understand what you got wrong
Why: Answer keys help you identify which topics you need to study more. When multiple questions are marked False, it indicates areas where you may have misconceptions that need correction.
Right-of-Way Rules
2. You are turning right and a bicyclist is approaching on your right. What should you do?
- Let the bicyclist go through the intersection first
- Turn quickly before the bicyclist reaches you
- Signal the bicyclist to stop and wait
Correct answer: Let the bicyclist go through the intersection first
Why: The handbook states that if a motorist is turning right and a bicyclist is approaching on the right, the motorist should let the bicyclist go through the intersection first before making the right turn.
Alcohol & Drugs
3. What is the only effective way to remove alcohol from the body?
- Strong coffee
- Time
- Cold shower
Correct answer: Time
Why: Only time allows the liver to metabolize alcohol from the body. Coffee, cold showers, and other remedies do not actually reduce blood alcohol content, though they may make someone feel more alert.
Speed & Following Distance
4. During your driving exam, what will you be tested on regarding speed?
- Proper speed usage
- Following posted speed limits
- Maintaining consistent speed
Correct answer: Proper speed usage
Why: The handbook specifically lists 'Proper speed usage' as one of the abilities you will be graded on during the driving exam. This is a direct requirement from the official testing criteria.
Parking Rules
5. When parking downhill on a street with a curb, which direction should you turn your front wheels?
- Toward the curb
- Away from the curb
- Straight ahead
Correct answer: Toward the curb
Why: When parking downhill with a curb, you turn wheels toward the curb so if the car rolls, it will hit the curb instead of rolling into traffic.
