5 sample questions with answers
Signs & Signals
1. You see a solid white line with a bicycle insignia along the side of the road. What does this mean?
- The area is designated for bicycle traffic only
- Cars can use this lane when no bicycles are present
- This is a shared lane where cars and bicycles travel together
Correct answer: The area is designated for bicycle traffic only
Why: A solid white line with a bicycle insignia indicates an area designated for bicycle traffic only. This is a specific pavement marking that drivers must recognize to avoid entering bicycle-only areas.
Right-of-Way Rules
2. You're turning right at an intersection with dashed bike lane lines and a bicyclist is already in the bike lane. What must you do?
- Yield to the bicyclist already in the bike lane
- Merge into the bike lane since the dashed line allows it
- Sound your horn to warn the bicyclist to move
Correct answer: Yield to the bicyclist already in the bike lane
Why: Even though dashed bike lane lines allow drivers to merge right for turning, drivers must still yield to bicyclists who are already occupying that space. The dashed line permits merging but doesn't override basic right-of-way rules.
Alcohol & Drugs
3. You receive a Notice of Suspension for failing an alcohol test. How many days do you have to request an administrative hearing?
- 7 days
- 30 days
- 14 days
Correct answer: 7 days
Why: The handbook clearly states you have the right to request an administrative hearing within seven (7) days of the date on the notice of suspension.
Speed & Following Distance
4. You're driving in heavy rain and see red taillights ahead. What should you do?
- Slow down more because the vehicle may be stopped or creeping along
- Maintain your current speed since they're just brake lights
- Speed up to pass them quickly before conditions worsen
Correct answer: Slow down more because the vehicle may be stopped or creeping along
Why: Red taillights ahead in poor weather conditions indicate a vehicle that may be stopped or moving very slowly. You should slow down more than usual to avoid rear-ending them.
Parking Rules
5. Who is allowed to park in handicapped parking spaces marked with the handicapped symbol?
- Only vehicles displaying the handicapped symbol on their license plate or special card
- Anyone with a disabled passenger in the vehicle
- Anyone making a quick stop to help a handicapped person
Correct answer: Only vehicles displaying the handicapped symbol on their license plate or special card
Why: Only vehicles displaying the handicapped symbol on their license plate or a special card may park in handicapped spaces. This is a specific legal requirement with clear identification needed.
