PA DMV Traffic Laws and Regulations 1 — Questions and Answers
Question 1: What should you do when approaching a stop sign?
- Slow down and proceed if the way is clear
- Stop only if there are other vehicles present
- Come to a complete stop and proceed when safe (Correct answer)
- Ignore the stop sign if you are in a hurry
Correct answer: Come to a complete stop and proceed when safe
A stop sign legally mandates that drivers bring their vehicle to a complete halt before the stop line or crosswalk. This ensures that drivers have a clear view of the intersection and can safely check for cross-traffic, pedestrians, or other hazards. Proceeding is only permissible once the way is clear and safe.
Question 2: What does a solid yellow line on your side of the road indicate?
- You may pass other vehicles
- No passing allowed (Correct answer)
- The lane is reserved for turning only
- You can park there temporarily
Correct answer: No passing allowed
A solid yellow line on your side of the road indicates that passing is strictly prohibited in that area. This marking is used in locations where visibility is limited, such as on hills or curves, or where it would be unsafe to cross into the opposing lane of traffic. Drivers must not cross a solid yellow line to overtake another vehicle.
Question 3: If you are involved in a minor accident with no injuries, what is the first thing you should do?
- Exchange insurance information with the other driver
- Immediately call the police
- Move your vehicle off the road if it is causing a hazard (Correct answer)
- Leave the scene and go home
Correct answer: Move your vehicle off the road if it is causing a hazard
In a minor accident without injuries, the immediate priority after ensuring everyone's safety is to prevent further incidents. Moving your vehicle off the road, if it is safe to do so and the vehicle is operable, clears the roadway. This action reduces the risk of additional collisions and helps maintain traffic flow.
Question 4: What is the legal blood alcohol concentration (BAC) limit for drivers over 21 years old in Pennsylvania?
- 0.05%
- 0.08% (Correct answer)
- 0.10%
- 0.12%
Correct answer: 0.08%
In Pennsylvania, the legal blood alcohol concentration (BAC) limit for drivers 21 years of age or older is 0.08%. Driving with a BAC at or above this threshold is considered driving under the influence (DUI) and is subject to significant legal penalties. This limit is set to ensure public safety by deterring impaired driving.
Question 5: What should you do when you see a school bus with its red lights flashing and stop sign extended?
- Continue driving but proceed cautiously
- Stop only if you are traveling in the same direction as the bus
- Stop your vehicle regardless of the direction you are coming from (Correct answer)
- Only stop if you are traveling in the opposite direction of the bus
Correct answer: Stop your vehicle regardless of the direction you are coming from
When a school bus displays flashing red lights and extends its stop sign, all traffic, regardless of the direction of travel, must stop. This law is in place to protect children who may be entering or exiting the bus and crossing the road. Drivers must remain stopped until the lights are off and the stop sign is retracted.
