Pennsylvania Driver's Manual (PUB 95), page 30: “Slow down and proceed with care”
3. How far from a crosswalk at an intersection are you prohibited from parking?
Answer: Within 20 feet. The handbook lists 'Within 20 feet of a crosswalk at an intersection' as a prohibited parking location.
Pennsylvania Driver's Manual (PUB 95), page 57: “Within 20 feet of a crosswalk at an intersection.”
4. According to the handbook, how far before turning must you signal if you are driving less than 35 mph?
Answer: At least 100 feet. The handbook states that for speeds under 35 mph, the required signaling distance is at least 100 feet.
Pennsylvania Driver's Manual (PUB 95), page 48: “Under Pennsylvania law, you must always use your turn signals at least 100 feet before turning, if you are driving less than 35 mph.”
5. What is the recommended procedure if you miss your exit on a highway?
Answer: Take the next exit. The handbook advises taking the next exit rather than performing hazardous maneuvers like backing up or crossing the median.
Pennsylvania Driver's Manual (PUB 95), page 56: “If you miss your exit, take the next one.”
6. How many seconds before your turn should you signal according to the section on completing a turn safely?
Answer: Three (3) to four (4) seconds. The handbook specifies that drivers should signal three to four seconds prior to making a turn.
Pennsylvania Driver's Manual (PUB 95), page 49: “Signal three (3) to four (4) seconds before your turn.”
7. When entering a circular intersection (roundabout), who has the right-of-way?
Answer: Drivers already in the circle. Traffic already circulating within the roundabout has priority over vehicles attempting to enter.
Pennsylvania Driver's Manual (PUB 95), page 52: “Drivers entering a circular intersection (or roundabout) must yield the right-of-way to drivers already in the circle.”
8. If a driver cannot move over for an emergency response area due to traffic conditions, what speed requirement must they follow?
Answer: Reduce speed to at least 20 miles per hour below the posted limit. When moving over is not possible, the law mandates slowing down by at least 20 mph below the posted limit.
Pennsylvania Driver's Manual (PUB 95), page 63: “If drivers cannot move over because of traffic or other conditions, they must reduce their speed to at least 20 miles per hour below the posted speed limit.”
9. According to Pennsylvania law, what is the minimum distance a driver must stop behind a school bus that has its red lights flashing and stop arm extended?
Answer: At least 10 feet away. The handbook states that drivers must stop at least 10 feet away from a stopped school bus with active signals.
Pennsylvania Driver's Manual (PUB 95), page 62: “When the bus stops with its red lights flashing and its stop arm extended, you must stop at least 10 feet away from the bus whether you are behind it or coming toward it on the same roadway or approaching an intersection at which the school bus is stopped.”
10. According to the handbook, what is the maximum legal speed indicated by a SPEED LIMIT sign?
Answer: The maximum legal speed under ideal conditions. The handbook defines the SPEED LIMIT sign as indicating the maximum legal speed specifically under ideal conditions.
Pennsylvania Driver's Manual (PUB 95), page 16: “A SPEED LIMIT sign indicates the maximum legal speed under ideal conditions for the stretch of highway where it is posted.”
11. When approaching an intersection, why should a driver look to the left first according to the 'left-right-left' rule?
Answer: Because vehicles coming from the left are closer to you. The handbook explains that the left is checked first specifically because vehicles approaching from that direction are physically closer to the driver.
Pennsylvania Driver's Manual (PUB 95), page 42: “Look to the left first, because vehicles coming from the left are closer to you.”
12. What does the 'KEEP RIGHT' sign direct drivers to do?
Answer: Keep to the right of the traffic island or divider. The handbook specifies that KEEP RIGHT signs instruct drivers to stay to the right of islands or dividers.
Pennsylvania Driver's Manual (PUB 95), page 16: “These signs direct drivers to keep to the right of the traffic island or divider.”
13. What is the primary function of the WRONG WAY sign?
Answer: To catch your attention if you accidentally turn onto a one-way street or ramp. The handbook explains that WRONG WAY signs are positioned to alert drivers who have inadvertently entered a one-way street or ramp in the incorrect direction.
Pennsylvania Driver's Manual (PUB 95), page 15: “WRONG WAY signs are placed farther down the one-way street or ramp. They are placed there to catch your attention, if you accidentally turn onto the street or ramp.”
14. When is it considered safe to stop halfway across a street while crossing traffic?
Answer: Only when there is a center median large enough to hold your entire vehicle. The handbook clarifies that stopping mid-crossing is permissible only if a sufficiently large center median exists to accommodate the vehicle.
Pennsylvania Driver's Manual (PUB 95), page 50: “Stopping halfway across a street is safe only when there is a turning lane provided in the center median large enough to hold your entire vehicle.”
15. What is the purpose of escape or runaway ramps on long downgrades?
Answer: To be used only by large vehicles that are out of control or cannot stop. The handbook specifies that these ramps are exclusively for large vehicles experiencing brake failure or loss of control.
Pennsylvania Driver's Manual (PUB 95), page 62: “These ramps are to be used only by large vehicles that are out of control or cannot stop because of brake failure.”
16. What is the correct action when a motorcycle's turn signal is flashing?
Answer: Wait until you see the motorcycle actually turning before pulling out. Because motorcycle turn signals may not auto-cancel, drivers should verify the actual movement before proceeding.
Pennsylvania Driver's Manual (PUB 95), page 60: “Do not pull out in front of a motorcycle/moped until you see it actually turning.”
17. What is the minimum clear roadway distance required to safely pass a slower vehicle on a two-lane road at 45 mph?
Answer: 1/4 mile. The handbook specifies that at 45 mph, a driver needs 1/4 mile of clear road to safely complete a passing maneuver.
Pennsylvania Driver's Manual (PUB 95), page 51: “At 45 mph, this translates into 1/4 mile of clear roadway you need to safely pass a slower vehicle.”
18. What is the minimum distance other drivers should be from you when choosing a place to make a U-turn?
Answer: At least 500 feet away. The handbook specifies that for a safe U-turn, approaching drivers must be at least 500 feet away and able to see the vehicle clearly.
Pennsylvania Driver's Manual (PUB 95), page 50: “In choosing a place to make a U-turn, make sure drivers coming from all directions are at least 500 feet away from you, and they can see you clearly.”
19. If two vehicles arrive at a four-way stop intersection at the same time, which driver must yield?
Answer: The driver on the left yields to the driver on the right. The handbook specifies that in a simultaneous arrival scenario at a four-way stop, the driver on the left is required to yield to the driver on the right.
Pennsylvania Driver's Manual (PUB 95), page 14: “If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.”
20. What is the required speed limit when yellow lights are flashing on a school zone speed sign?
Answer: 25 miles per hour. The handbook lists 25 miles per hour as the correct speed limit for this scenario.
Pennsylvania Driver's Manual (PUB 95), page 31: “THE SPEED LIMIT IS _______ MILES PER HOUR WHEN THE YELLOW LIGHTS ARE FLASHING ON THE SCHOOL ZONE SPEED SIGN. A. 25”
