A pedestrian who is blind is crossing at an intersection using a white cane or a guide dog, even though the traffic signal does not currently favor them. What must a driver do?
- Always yield to the pedestrian, no matter the signal
- Wait for a police officer to direct the pedestrian across
- Sound the horn so the pedestrian knows to hurry
- Proceed if no other pedestrians are visible

A driver's eyes stay on the road and both hands stay on the wheel, but their mind wanders to a stressful phone call they just had. What type of distraction is this?
- Visual distraction
- Cognitive distraction - the mind is off the driving task
- Manual distraction
- This is not considered a distraction since the eyes are on the road
Correct answer: Cognitive distraction - the mind is off the driving task. Cognitive distraction is mental, not physical - a driver can be looking straight ahead and still be dangerously distracted if their mind isn't on driving.

A motorcyclist ahead is slowing down, but the driver behind does not see a brake light come on. Why might this happen?
- Motorcycles are not equipped with brake lights
- It means the motorcyclist is actually speeding up, not slowing
- The rider may be slowing by downshifting, and the brake light is also easy to miss
- State law does not require motorcycle brake lights to work
Correct answer: The rider may be slowing by downshifting, and the brake light is also easy to miss. A motorcyclist can slow down by downshifting or rolling off the throttle without the brake light ever coming on, and because motorcycle tail lights are smaller, even a lit brake light can be easy to miss. A driver should not assume a motorcycle isn't slowing just because no brake light is visible.

At a wide intersection, why should a driver avoid swinging wide while turning right?
- It automatically cancels your turn signal setting
- It has no real effect on your safety at all
- It shortens the distance needed to complete the turn
- It can carry the vehicle into the oncoming lane
Correct answer: It can carry the vehicle into the oncoming lane. A right turn taken too wide can drift the vehicle across the centerline into traffic coming from the opposite direction.

Besides work and school activities, what other situation excuses driving alone during these hours?

If a young passenger in the vehicle is not properly buckled in or secured in a car seat, who is typically held responsible under state law?
- Only the child's legal guardian, even if they are not in the car
- The driver, who can be cited for the unbuckled child passenger
- No one - child passengers are not covered by seat belt laws
- Only the vehicle's registered owner, if different from the driver
Correct answer: The driver, who can be cited for the unbuckled child passenger. States generally place responsibility on the driver to make sure young passengers are properly restrained, and the driver can be cited if they are not.
Source: California Driver Handbook, Occupant Protection-Seat Belts p.27 - 'If the passenger is under 16 years old, you may be cited if they are not wearing their seat belt.'
A driver turns on the windshield wipers because of rain. What should they also do?
- Turn on the headlights, even in daytime
- Turn off the headlights to save the battery
- Nothing else is needed during the day
- Turn on the hazard flashers instead
Correct answer: Turn on the headlights, even in daytime. Whenever the wipers are needed to clear rain from the windshield, a driver should also turn on the headlights, even during the day, so the vehicle is easier for other drivers to see.

A driver sees a yellow diamond warning sign showing a curve, but does not slow down because the road looks straight at that moment. What is wrong with this?
- Nothing; warning signs can be ignored if the road looks fine
- Warning signs are placed in advance, so the hazard may not be visible yet
- The sign only applies to trucks
- The sign only applies at night
Correct answer: Warning signs are placed in advance, so the hazard may not be visible yet. Warning signs are posted before the hazard to give drivers time to react, so the curve or hazard may still be out of sight when the sign appears.

- Keep a foot on the brake pedal at all times.

A large truck is passing a car on the highway. What should the driver of the car do?
- Speed up to make the truck's pass shorter
- Keep to their side of the lane and not speed up
- Move toward the center of the lane
- Flash the high beams until the truck finishes passing
Correct answer: Keep to their side of the lane and not speed up. When a truck is passing, the driver being passed should keep to their own side of the lane and avoid speeding up, which would only extend how long the truck has to stay in the passing lane.

- Two side roads ahead meet your road directly across from each other at the same point

A driver has just parked along a curb where bicyclists ride by. Before opening the car door, what should the driver do?
- Open the door quickly so bicyclists can see it in time
- Look behind for an approaching bicyclist before opening the door
- Nothing extra, since bicyclists must watch for parked cars
- Only check mirrors, since a bicyclist would be heard first
Correct answer: Look behind for an approaching bicyclist before opening the door. Opening a car door into the path of a passing bicyclist can cause a serious crash. Before opening the door, a driver (or any occupant) should look behind for approaching bicyclists.

- 15 feet

On snow or ice, how should a driver approach the idea of a 'safe' speed?
- Drive the posted speed limit exactly, since it already fully accounts for weather and road surface conditions today
- Drive 10 mph under the posted limit and no slower
- Speed does not need to change if you have good tires
- There is no fixed safe speed for snow or ice; reduce speed, judge traction, and increase following distance
Correct answer: There is no fixed safe speed for snow or ice; reduce speed, judge traction, and increase following distance. There is no single safe speed for snow or ice. Drivers must be extremely cautious, reduce speed substantially, and increase following distance until they can judge how much traction their tires have.

You arrive at a crosswalk and the pedestrian signal shows a steady, non-flashing DON'T WALK (or a steady raised hand). What should you do?
- Wait; do not begin crossing
- Cross quickly before traffic arrives
- Cross only if no cars are visible
- Cross if you are in a hurry
Correct answer: Wait; do not begin crossing. A steady DON'T WALK signal means it is not legal to begin a new crossing; a pedestrian should wait for the WALK signal.

A steady red "X" displayed above a lane on the highway means what?
- Do not drive in that lane

Source: Florida Driver Handbook, PDF p.60, Red X: never drive in a lane under the red X
