5 sample questions with answers
Signs & Signals
1. When you approach a traffic signal that is not working due to a power outage, what should you do?
- Treat it as a four-way stop
- Proceed with caution without stopping
- Treat it as a flashing red light
Correct answer: Treat it as a four-way stop
Why: By law, drivers must treat non-working traffic signals as four-way stops, meaning you must come to a complete stop and proceed when safe.
Right-of-Way Rules
2. When merging onto a multi-lane highway, who has the right-of-way?
- Traffic already on the highway
- The merging vehicle if it signals properly
- Whichever vehicle reaches the merge point first
Correct answer: Traffic already on the highway
Why: Traffic already on the highway always has the right-of-way over merging traffic. Merging drivers must yield and find a safe gap to enter traffic.
Alcohol & Drugs
3. What is the legal blood alcohol concentration (BAC) limit for drivers under age 21 in Ohio?
- .02% or higher
- .04% or higher
- .08% or higher
Correct answer: .02% or higher
Why: Ohio has a zero-tolerance policy for underage drinking and driving. Drivers under 21 face penalties at .02% BAC or higher, which is much lower than the standard .08% limit for adults.
Speed & Following Distance
4. When driving in fog, how should you follow the vehicle ahead?
- Keep a consistent distance and drive slower, ready to stop at any time
- Follow closer than normal so you don't lose sight of the vehicle
- Maintain normal following distance and speed to keep traffic moving
Correct answer: Keep a consistent distance and drive slower, ready to stop at any time
Why: The handbook instructs to keep a consistent distance behind the vehicle in front while driving slower with the expectation you may need to stop at any time. This maintains safe following distance in reduced visibility.
Parking Rules
5. How close to a fire hydrant can you legally park your vehicle?
- Within 10 feet of a fire hydrant
- Within 15 feet of a fire hydrant
- Within 5 feet of a fire hydrant
Correct answer: Within 10 feet of a fire hydrant
Why: Ohio law specifically prohibits parking within 10 feet of a fire hydrant to ensure emergency vehicles can access the hydrant quickly.
