GDL Adverse Weather and Road Conditions 1 — Questions and Answers
Question 1: Under GDL rules, what is the recommended action for a new driver when it begins to rain heavily?
- Maintain normal speed since rain rarely causes accidents
- Reduce speed and increase following distance (Correct answer)
- Turn on hazard lights and continue at the same speed
- Pull into the left lane to avoid puddles on the right
Correct answer: Reduce speed and increase following distance
Rain reduces tire traction and visibility, so new drivers should reduce speed and increase following distance to allow more stopping time.
Question 2: When driving on a wet road, a new GDL driver should increase their following distance to at least how many seconds?
- 2 seconds
- 3 seconds
- 4–5 seconds (Correct answer)
- 1 second
Correct answer: 4–5 seconds
On wet roads, braking distances increase significantly, so a following distance of at least 4–5 seconds is recommended for new drivers.
Question 3: What is hydroplaning?
- Skidding caused by worn brake pads
- A vehicle sliding on a thin layer of water on the road surface (Correct answer)
- Fishtailing due to rear-wheel drive
- Oversteering when making a sharp turn
Correct answer: A vehicle sliding on a thin layer of water on the road surface
Hydroplaning occurs when tires ride on a layer of water rather than the road surface, causing loss of steering control.
Question 4: If a GDL permit holder begins to hydroplane, what should they do?
- Brake hard and steer sharply to the shoulder
- Accelerate to push through the water
- Ease off the gas and steer straight until traction returns (Correct answer)
- Engage the emergency brake immediately
Correct answer: Ease off the gas and steer straight until traction returns
Easing off the accelerator and steering straight allows the tires to regain contact with the road without causing a spin.
Question 5: When driving in fog, a new driver should use:
- High-beam headlights to see farther ahead
- Low-beam headlights or fog lights (Correct answer)
- Hazard lights only, no headlights
- No lights, since they reflect off fog
Correct answer: Low-beam headlights or fog lights
Low-beam headlights or dedicated fog lights aim downward and reduce glare, improving visibility in foggy conditions.
Question 6: A GDL driver encounters black ice on a bridge. What is the safest action?
- Brake firmly to reduce speed quickly
- Steer sharply to the right to reach the shoulder
- Release the gas pedal gently and avoid sudden inputs (Correct answer)
- Accelerate to clear the ice quickly
Correct answer: Release the gas pedal gently and avoid sudden inputs
On black ice, sudden braking or steering can trigger a spin; the safest action is to reduce speed gradually with no abrupt inputs.
Question 7: In which situation should a GDL driver consider pulling over and waiting rather than continuing to drive?
- Light rain with good visibility
- Sunny weather with mild wind
- Whiteout snow conditions with near-zero visibility (Correct answer)
- Overcast skies with dry pavement
Correct answer: Whiteout snow conditions with near-zero visibility
Whiteout conditions make it impossible to see road markings or other vehicles, making driving extremely dangerous for any driver, especially inexperienced GDL holders.
