PA DMV Vehicle Operation and Control 3 — Questions and Answers
Question 1: When towing a trailer in Pennsylvania, you must use safety chains that are:
- Long enough to allow the trailer to turn freely without tangling
- Crossed under the trailer tongue in an X pattern (Correct answer)
- Attached only to the trailer hitch ball
- Slack enough to lie flat on the ground
Correct answer: Crossed under the trailer tongue in an X pattern
Safety chains must be crossed under the trailer tongue in an X pattern to cradle the tongue if it detaches.
Question 2: How does carrying a heavy load in your vehicle affect braking distance?
- It decreases braking distance due to added traction
- It increases braking distance because of greater momentum (Correct answer)
- It has no effect on braking distance
- It only affects braking on wet roads
Correct answer: It increases braking distance because of greater momentum
A heavier vehicle has more momentum and therefore requires greater braking distance to stop safely.
Question 3: What should you do when driving in dense fog?
- Use high beams to see farther ahead
- Use low beams and reduce speed significantly (Correct answer)
- Use hazard lights as your primary lighting
- Follow the taillights of the vehicle ahead closely
Correct answer: Use low beams and reduce speed significantly
Low beams reduce glare in fog and, combined with reduced speed, give you more reaction time.
Question 4: Which of the following is the best technique for driving on icy roads?
- Keep your speed constant and avoid any braking
- Accelerate, brake, and steer gradually and smoothly (Correct answer)
- Use cruise control to maintain a steady speed
- Stay in the center lane to avoid ice near the edges
Correct answer: Accelerate, brake, and steer gradually and smoothly
Smooth, gradual inputs for acceleration, braking, and steering prevent wheel spin and skidding on ice.
Question 5: What is the correct hand position recommended for modern vehicles equipped with airbags?
- 10 and 2 o'clock
- 9 and 3 o'clock (Correct answer)
- 8 and 4 o'clock
- 12 o'clock with one hand
Correct answer: 9 and 3 o'clock
The 9 and 3 position keeps hands away from the airbag deployment zone and provides good vehicle control.
Question 6: When your vehicle begins to hydroplane, you should:
- Brake hard to regain road contact
- Ease off the accelerator and hold the steering wheel straight (Correct answer)
- Turn the wheel sharply to break the water layer
- Accelerate briefly to push through the water
Correct answer: Ease off the accelerator and hold the steering wheel straight
Easing off the gas and steering straight allows tires to gradually regain contact with the road surface.
Question 7: In Pennsylvania, how far from a railroad crossing must you stop if a signal is flashing?
- 5 feet
- 15 feet (Correct answer)
- 50 feet
- 100 feet
Correct answer: 15 feet
Pennsylvania law requires stopping no closer than 15 feet from the nearest rail when a railroad signal is active.
