BMV BMV Traffic Laws 1 — Questions and Answers
Question 1: What is the legal blood alcohol concentration (BAC) limit for drivers 21 and over?
- 0.08% (Correct answer)
- 0.10%
- 0.05%
- 0.02%
Correct answer: 0.08%
The legal BAC limit for drivers 21 and over is 0.08% in all US states. Driving at or above this level constitutes DUI/DWI.
Question 2: When approaching a school bus with flashing red lights, what must you do?
- Stop and remain stopped until the lights stop flashing and the stop arm is retracted (Correct answer)
- Slow down and proceed with caution
- Honk to alert the children
- Pass on the left side only
Correct answer: Stop and remain stopped until the lights stop flashing and the stop arm is retracted
All vehicles must stop when a school bus displays flashing red lights and/or an extended stop arm, regardless of direction of travel (unless separated by a physical median), remaining stopped until signals are deactivated.
Question 3: What does a solid yellow line on your side of the road mean?
- No passing — you cannot cross this line to pass another vehicle (Correct answer)
- Passing is allowed with caution
- The lane is for emergency vehicles only
- The road is under construction
Correct answer: No passing — you cannot cross this line to pass another vehicle
A solid yellow line on your side means passing is prohibited in your direction. A broken yellow line means passing is allowed if safe. Double solid yellow lines mean no passing in either direction.
Question 4: What is the proper procedure at a four-way stop intersection?
- The first vehicle to arrive has the right of way; if arriving simultaneously, yield to the vehicle on the right (Correct answer)
- The largest vehicle always goes first
- The vehicle traveling fastest goes first
- There is no specific procedure
Correct answer: The first vehicle to arrive has the right of way; if arriving simultaneously, yield to the vehicle on the right
At a four-way stop, vehicles proceed in order of arrival. When two vehicles arrive simultaneously, the vehicle on the right has right of way. If facing each other, the vehicle going straight has priority over one turning.
Question 5: What is the safe following distance rule?
- At least 3-4 seconds behind the vehicle ahead under normal conditions (Correct answer)
- One car length for every 10 mph
- As close as possible to draft behind the vehicle ahead
- No specific rule exists for following distance
Correct answer: At least 3-4 seconds behind the vehicle ahead under normal conditions
The 3-4 second rule provides adequate stopping distance under normal conditions. Increase to 5-6 seconds in adverse conditions (rain, fog, night). Tailgating is a leading cause of rear-end collisions.
Question 6: When are you required to use headlights?
- From sunset to sunrise, during rain, fog, snow, and when visibility is less than 1,000 feet (Correct answer)
- Only at night when it is completely dark
- Only during heavy rain
- Only on highways
Correct answer: From sunset to sunrise, during rain, fog, snow, and when visibility is less than 1,000 feet
Headlights are required from sunset to sunrise, during any precipitation (rain, snow, sleet), fog, smoke, or any condition reducing visibility below 1,000 feet, and when windshield wipers are in use.
