1. When is a driver or rider most likely to need hand and arm signals instead of the vehicle turn signal lamps?
Show answer
Answer D: When the lamps have failed or cannot be seen because of glare or a load
Hand and arm signals replace or reinforce the lamps whenever the lamps do not work or cannot be seen clearly by other road users.
-
2. An emergency vehicle is stopped on the shoulder ahead with its lights flashing. What does the move over principle require?
Show answer
Answer D: Change lanes away from it, or slow down if you cannot
Move over laws ask you to give responders an empty lane, and where traffic or a two-lane road makes that impossible, you slow down instead.

3. Where is reflective material most effective at attracting a driver's attention at night?
Show answer
Answer A: On the arms, legs and helmet, where the movement draws the eye
Reflective patches that move as the rider rides are noticed sooner than static ones, and a helmet sits high where drivers are already looking.

4. How long should a head check before a lane change last?
Show answer
Answer D: A quick glance, so you do not lose track of what is happening ahead
Traffic ahead can change in a second, so the blind spot check is a fast glance and the rider returns attention to the road immediately.
-
5. How should braking and swerving be combined?
Show answer
Answer C: Brake before or after the swerve, never during it
Traction can be spent on turning or on braking, and asking for both at once during a swerve is very likely to cause a skid.
-
6. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
7. For an alert driver, about how long is the reaction time once a hazard has been recognized?
Show answer
Answer A: About three quarters of a second
Reaction alone takes roughly three quarters of a second for an alert driver, and perception takes about as long again, so a second and a half of travel is added before the brakes bite.
-
8. How much of a traffic lane is a motorcycle entitled to use?
Show answer
Answer D: The full width of the lane
A motorcycle is entitled to the full lane, and riders move within it to stay visible and to avoid surface hazards, so drivers should never try to share a lane with one.
-
9. Your left-turn lane shows a flashing yellow arrow. What does that indication allow?
Show answer
Answer B: A left turn after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow marks a permissive left turn: the movement is allowed, but oncoming vehicles and pedestrians keep the right-of-way.
-
10. Which facility does this sign direct a traveler toward?
Show answer
Answer B: A hospital offering emergency care
This is the standard marker for medical care, used to lead a traveler to a hospital where emergency treatment is available.
