The 10 Most Commonly Missed DMV Questions
Based on data from thousands of practice test attempts, these are the topics that trip people up the most:
1. Following Distance
Rule: Keep at least 3–4 seconds of following distance behind the car in front of you. Increase to 5–6 seconds in bad weather.
Many test-takers pick "2 seconds" or "one car length" — both are wrong.
2. BAC Legal Limit
Rule: The legal blood alcohol content (BAC) limit is 0.08% for drivers 21 and older. For drivers under 21, it is 0.00% to 0.02% in most states (zero tolerance).
People often mix up the adult and underage limits.
3. What to Do at a Flashing Yellow Light
Rule: Slow down and proceed with caution. You do NOT need to stop (that's a flashing red light).
4. When to Use Headlights
Rule: Turn on your headlights 30 minutes after sunset and keep them on until 30 minutes before sunrise. Also use them whenever visibility is less than 1,000 feet.
5. Right of Way at a Four-Way Stop
Rule: The first vehicle to arrive at the intersection goes first. If two vehicles arrive at the same time, the vehicle on the right goes first.
6. What a Solid Yellow Line Means
Rule: A solid yellow center line means no passing from your side. A broken yellow line means passing is allowed when safe.
7. School Zone Speed Limits
Rule: The speed limit in a school zone is typically 15–25 mph when children are present. The exact limit varies by state.
8. Parking on a Hill
Rule: When parking uphill with a curb, turn your wheels away from the curb. When parking downhill, turn your wheels toward the curb. When there is no curb, always turn toward the edge of the road.
Memory trick: "Up and away, down and toward."
9. When to Pull Over for Emergency Vehicles
Rule: When you hear a siren or see flashing lights, pull over to the RIGHT side of the road and stop. Wait until the emergency vehicle passes before moving.
10. Blind Spot Checks
Rule: Always turn your head to check your blind spot before changing lanes or merging. Mirrors alone are not enough.
